Modern cars have complex charging systems controlled by the main computer of the vehicle.

00:00

Decades ago, the alternator would charge the battery, but now it is controlled by the main computer.

Modern cars have an electronic battery sensor that sends feedback information to the computer so it can control the charge correctly.

Jump-starting a car incorrectly can cause problems with the electronic battery sensor system.

✦

There are different types of batteries in modern cars, and using the wrong type can cause issues.

01:46

Some modern cars use absorbed glass mat (AGM) batteries, which require special recharging settings.

Replacing the battery in a BMW requires a fancy scan tool to reset the computer's power recognition.

If the battery management system is not reset when a new battery is installed, it can lead to overcharging and damage to the new battery.

✦

When replacing the battery in a car with a battery management system, it's important to reset the system using a scan tool.

05:27

Failure to reset the system can result in overcharging the new battery and causing it to be destroyed within a year.

There is a tool available for resetting the battery management system, but it's recommended to have a mechanic do it.

Another option is to use a memory keep alive device when changing or disconnecting the battery to prevent issues with the car's systems.

✦

The glass in modern car windshields is made of laminated glass, which includes a layer of glass, a vinyl layer, and another layer of glass to prevent shattering.

06:31

The laminated glass in windshields has been a standard feature in cars for a while.

✦

Cars have two types of side glass: laminated glass and tempered glass.

07:00

Originally, cars came with laminated glass for side windows.

After a change in US laws, cars now use tempered glass for side windows.

Tempered glass shatters into small pieces upon impact, while laminated glass stays in place.

In a rollover, the little hammer devices used to break glass may not work for laminated glass.

✦

It's important to know what type of glass your car has to be prepared for emergencies.

09:00

Tempered glass will shatter, allowing you to escape in an emergency.

Laminated glass may not shatter, trapping you inside in an emergency.

Check if your car has laminated or tempered glass on the side windows.

Knowing the type of glass ahead of time can prevent expensive repairs and ensure safety.

✦

Inquire about the type of glass in your car (laminated or tempered) to be prepared for emergencies.

09:00

Provide your car's VIN number to find out the type of glass used.

Knowing the type of glass can prevent being trapped in a rollover situation.

✦

Cars with laminated glass on the side windows may not be easily escapable in emergencies.

09:00

Check if your car has laminated or tempered glass on the side windows.

Laminated glass may not shatter when using emergency escape tools like hammers.

✦

The 2013 Toyota Camry 4 cylinder may lose power above 4,500 revolutions per minute due to sensor issues.

10:00

Three codes (P0717, P1603, P1605) related to rough idling and engine stall indicate sensor issues.

Sensor one (oxygen sensor/air fuel ratio sensor) before the catalytic converter was found to be the problem.

Replacing the sensor with an original equipment one from Toyota fixed the issue.

Using a cheap aftermarket sensor like Bosch may not work well.

00:05 today I'm gonna talk about some changes

00:08 in modern cars that you may not know

00:11 about no the first thing I got to talk

00:12 about is your car's battery and the

00:15 charging system the alternator you've

00:17 gotten very complicated lately but if

00:19 you understand their complexity you

00:21 won't fall into a trap that I've seen

00:23 many other people fall into for a lack

00:25 of knowledge it used to be the charging

00:27 system was simple the battery would

00:29 stock the car sending power to the

00:31 starter running the ignition and fuel

00:32 system and the alternator would charge

00:36 the battery decades ago companies like

00:39 Honda decided to get better gas mileage

00:41 they would have the alternator charging

00:44 controlled by the main computer of the

00:46 vehicle when they started out with those

00:48 systems I saw a lot of guys mechanics

00:50 included that would replace an

00:52 alternator in a car that wasn't charging

00:54 only to find that it didn't charge

00:55 either because it was a problem in the

00:57 computer system which is something you

00:59 don't want to occur so you want to

01:01 prevent it now in many modern cars

01:03 there's a sensor called the electronic

01:06 battery sensor it's on the negative

01:08 terminal going to the frame engine - it

01:10 grounds the whole vehicle the engines

01:12 transmission and the body of the car Wow

01:15 this electronic sensor sends feedback

01:18 information to the computer about the

01:20 battery voltage temperature sun's the

01:23 information so the computer can control

01:25 the charge incorrectly now the way these

01:28 things are set up today in a modern

01:30 computerized car you have to jumpstart

01:33 them correctly or you're gonna have a

01:34 problem with that system a lot of times

01:37 if you do jump start a car incorrectly

01:39 it won't run right after you do that so

01:42 all you gotta do is follow this follow

01:44 the directions that jump-starting a car

01:46 this way get you jump starter with the

01:48 positive on the positive terminal and

01:50 then get the negative for your jump

01:52 stick it on a gunmetal fire right here

01:55 there's a bracket right on the engine

01:56 block now originally people said you're

01:59 supposed to jumpstart a car that way

02:01 anyway because when you connect the last

02:04 cable a second one sometimes there's a

02:06 spark and if the spark is right up by

02:09 the battery sometimes you could have an

02:11 explosion from the hydrogen gas that

02:12 comes

02:13 now it's a very rare thing it generally

02:16 only happens if a battery is somewhat

02:18 frozen or if you're in an enclosed area

02:20 I'm outside here so I really don't care

02:22 I never had any problems with it but now

02:24 you really need to do this because of

02:27 that electronic battery sensor because

02:29 if you jump-started it and put the

02:31 negative from your jumper on the battery

02:35 the car would start but the sensor on

02:38 that negative terminal is further down

02:40 and it messes with how it reads and once

02:43 you start the car often bad things will

02:46 happen why not I don't write the

02:48 charging system might not charge

02:49 correctly now if you did jumpstart it

02:52 wrong it doesn't do any permanent damage

02:53 but you have to visit a mechanic like me

02:55 that has a fancy scan tool then we go

02:58 through our scan tool stuff and we'd get

03:00 to the suction where we had reset the

03:02 electronic battery sensor system so

03:05 would work correctly but if you

03:07 jump-started by putting the negative

03:09 terminal on the engine somewhere you

03:11 don't have to worry about that so

03:12 jumpstart him that way

03:13 ain't no to worry about messing up that

03:15 stupid sensor system that many of the

03:17 computerized cars have these days now

03:19 the next thing we're gonna talk about

03:20 modern cars is the batteries yesterday

03:24 when you replace the battery you replace

03:26 it with the same style battery had the

03:28 same cranking amps cold cranking amps

03:30 but today there's various types of

03:32 batteries out there and you want to make

03:34 sure you're putting the right one in

03:35 your car as a replacement you got an old

03:37 car like this is just a let acid battery

03:39 no big deal let's say your car came with

03:41 an absorbed glass mat battery the marks

03:44 bounce up there more power they tend to

03:46 last longer crank a lot better but if

03:48 your car has one of those in it you have

03:51 to replace that battery with another

03:53 absorbed glass mat battery because I

03:55 know the vehicles a little charging

03:57 system with the computer is designed for

03:59 that system the absorbed glass mat

04:02 battery stamped to be recharged

04:04 differently when I recharge them with my

04:06 fancy recharge or I have to put it on

04:08 the special setting for them you can't

04:10 just use the normal full blast

04:12 let s a battery charger or it won't be

04:15 charged correctly so make sure you

04:16 replace your battery with the correct

04:18 battery and in the case of quite a few

04:21 modern-day cars you will also have to

04:23 have the car reprogrammed for the new

04:25 battery and that's because of

04:27 further refinements in computer charging

04:30 technology the first company that really

04:32 want mass and that was BMW and when you

04:34 change the banner into BMW you have to

04:37 get a fancy scan tool hooked up to

04:39 restart it to tell the computer that its

04:41 power now has a brand new battery in it

04:43 now that's important because of the way

04:45 the software is designed you buy a brand

04:47 new BMW got a brand new battery let's

04:49 say it's four years old the computer in

04:51 your car knows it's four years old and

04:53 it tends to charge it more because an

04:55 old battery needs more charging to keep

04:57 it going but when it finally goes bad if

04:59 you replace the battery and just put it

05:02 in and don't reprogram the car it'll

05:04 start but your computer still thinks

05:06 that you've got a four year old battery

05:09 in the car it will charge it too much

05:10 overcharge the battery and often within

05:12 a year a new banner will be destroyed

05:15 now as you can see my fancy scam tool

05:17 he's got to cite you for that

05:18 BMS you just push that then you pick the

05:21 car that you're working on it has that

05:23 system and it allows you to reset it

05:25 we'll get a BMW here so what this

05:27 computer does when it's connected to a

05:30 BMW it isn't now but when it is it just

05:34 allows you to resets how you change the

05:36 Barry push buttons and then it resets

05:38 the whole system now you can't do this

05:40 yourself so if you find out that your

05:43 car was one of the cars on its list and

05:45 it has a battery management system that

05:48 has to be reset when you place the

05:50 battery you got to pay a mechanic to do

05:51 this because if you don't you're gonna

05:53 have problems down the line and you

05:54 might well ask Scotty what are they

05:56 making cars this insanely crazy well

05:58 because of course they can and they love

06:01 making stuff computer-controlled so

06:03 that's just the way it is realize you

06:07 got one of those cars when you have the

06:08 battery replace you're gonna have to pay

06:10 mechanic to reset the system you're not

06:12 gonna go buy one of these $3500 scan

06:14 tools you just pay somebody to reset it

06:16 I'd realize there is a tool you can use

06:18 when you change your battery or if you

06:20 disconnect your videos you're working on

06:21 the car that's one of these memory keep

06:24 alive systems this one was like I don't

06:26 know 12 13 bucks from Amazon it's very

06:29 simple this connects to any 12-volt

06:31 power supply and this it just plugs into

06:34 the OBD memory port there deep and so

06:38 you don't lose them

06:40 a car some of these cars minis BMWs even

06:44 Lincoln's you got automatic windows that

06:46 come up and then down a little when you

06:48 close them and then up automatically and

06:51 a lot of the systems they won't work the

06:53 car won't I don't write when you

06:55 disconnect the battery and either

06:56 replace it or work on a car and then

06:58 connect the back on if you have one of

07:00 these keep memory alive devices hooked

07:02 up you don't have to deal with any of

07:04 their crap so they're very handy things

07:05 and they're so cheap if you're gonna

07:07 work on your car if you're ever gonna

07:08 change a battery on your car you

07:09 definitely need to get one of these

07:11 other nuts changing technology you may

07:13 not know about has to do with the glass

07:15 in your car know your windshield has

07:17 always really made out of laminated

07:19 glass there's a layer of glass then

07:21 there's a vinyl layer in between and

07:23 then there's another layer of glass

07:25 under that's so it won't break and

07:28 shatter if you get the wreck and hit it

07:29 it'll crack but it won't cause jagged

07:32 pieces to come and comfy but the side

07:34 glass now originally they actually came

07:37 with laminated glass but ten years later

07:38 they changed the laws of the United

07:40 States and instead they have what they

07:42 call safety glass and this is tempered

07:44 glass it's made so that if it hits it

07:48 shatters into a zillion different pieces

07:50 it's not like the laminated stuff it's

07:53 cheaper to make but there's a little

07:54 tiny pieces that won't cut and if you're

07:57 in a wreck and you're stuck in the power

07:59 windows don't work anymore a lot of

08:00 people have those little hammers those

08:02 little glass headers that they pop on it

08:04 then it shatters then climb out the

08:06 window

08:06 well some of the newer cars they don't

08:10 use safety glass on the side they've

08:12 gone back to using laminated glass and

08:15 if you have a car like that and you get

08:16 in a rollover the little hammer devices

08:19 and the little ones that have a pin that

08:21 snaps and shatters the glass they won't

08:24 share it of the glass because it's

08:25 laminated glass you'll just stay there

08:27 so if you've got a relatively new car it

08:31 behooves you to find out does your car

08:33 have side glass that's the old-fashioned

08:36 tempered glass that will shatter or is

08:39 that the more modern laminated glass on

08:42 the side now you windshields always

08:43 gonna be laminated that's no problem but

08:45 the side ones they could go either way

08:47 now find out before you need to know the

08:51 last thing you want to know is if your

08:52 car rolls over he's talking

08:53 ditch and you can't get off gee I wonder

08:55 what kind of glass I have if I can break

08:57 it or not find out ahead of time

08:59 give them your in number and I can say

09:01 that has laminated glass or that has

09:03 tempered glass on the side easy to do

09:05 but you want to know now not if you're

09:07 in a pinch so now you know cars are

09:10 evolving they're becoming more

09:11 complicated that you should know a

09:13 little bit more about so you're not only

09:15 gonna stay safe you're gonna keep from

09:18 having to pay for a really expensive

09:19 repairs that you could have avoided in

09:22 the first place with a little knowledge

09:25 and here's some bonus questions and

09:28 answers Willy Wonka's a full-size 2013

09:32 Toyota Camry 4 cylinder I lose power

09:35 once it gets about 4,500 revolutions

09:38 I had a mechanic look at it he can't

09:41 figure it out it's got three codes po7

09:44 17p 1603 and P 1605 a rough idling

09:48 engine stalled input speed sensor

09:50 there's a lot of reasons cars can't rev

09:51 up too high you can't lie cavernous

09:53 clogged it'll do that

09:54 Toyota's are known for that if the fuel

09:55 pumps weak well the older Toyota's like

09:57 that aren't known for fuel pump problems

09:59 that's a new thing that they've made

10:00 something wrong and they got to recall a

10:02 bunch of them but that's newer than

10:03 yours

10:04 I fixed one a couple months ago with the

10:06 same exact problem I drove it around

10:08 with my scan tool hooked up erased the

10:10 codes the code started coming back I

10:12 pushed my record button and then I

10:14 looked at the data it turns out sensor

10:16 one oxygen sensor air fuel ratio sensors

10:19 but they look just like an oxygen sensor

10:21 that's the sensor that's before the

10:23 catalytic converter when I looked at

10:24 that data it was going on it would just

10:26 drop to zero so I checked the wiring it

10:28 was all ok so all I did was buy a new

10:30 sensor from Toyota the original

10:33 equipment one don't get a cheap

10:34 after-market one like a Bosch or

10:35 something they won't work get the

10:37 original equipment oxygen sensor bolted

10:39 on and it could easily fix a problem

10:40 because it did on mine thank goodness it

10:42 wasn't the computer because the computer

10:43 circuit could go out and do that - it

10:45 was the actual sensor itself I replaced

10:47 the bank one oxygen sensors one before

10:50 the catalytic converter fix the whole

10:51 thing

10:53 so if you never want to miss another one

10:55 of my new car repair videos remember to

10:57 ring that Bell
