How to Scan Your Car for Diagnostic Trouble Codes

[RunscapeHK]

pleas can you tell me the name of the Scanner the shows whats wrong with the cars!

Pleas Pm Me Back!

Thank you.

[chaconmcfly]

Damn, scanning your car in the USA is usually free at AutoZone, In here in Mexico, they charge me 60 dollar for scanning. And sometimes they don't even know what it means because they don't know how to read english and I have to be googling the problem myself. Aint't that a bitch?

[wickedclown2377]

in the newer model to reset the trouble codes it wont work to disconnect the battery the codes are store in the pcm memory bank

[ralphgo69]

no ,if your disconnect the battery sometimes mybe erase the codes but so the think is your need to use the scann for apropiate erase the codes .................

I like the new Actron Elite CP9185 , does a whole lot more, I plugged it in to my volvo 2001 which for at every 20k miles gives me a Service light fault, get the work done by my local cheaper automechanic and clear the code myself. Also , I check the code if I get a "check engine" fault light" ,its usually a gas cap off, or misfired plug. Easily fixed . Anyhow, you can look up your codes

on the internet. Cheap & Easy to fix - Got tired of paying 80 bucks at the dealer

to tell me the same thin

[monsterholics]

thats a fucking shitty scanner

[raguspag55]

@monsterholics it matters not what type of scanner one has, its how to read the code and diagnose / fix the problem. Usually by googling the code there

are hundreds of sites that show you what the code means and how to fix it,

at the very least you know what it is before the crooken mechanic takes it from ya!

[2ub40]

what about for older cars?

[Nicksolo85]

How much would a scan tool like that cost?

[Cabinetmaker09]

@Nicksolo85 They start out around 100 dollars and the more you spend the more it will do.

[cencal559jm]

@Nicksolo85 about $150 to $300

[ilayasaravanan]

he is not saying that knowing to use a scanner, replaces your diploma/degree. it is just a video on using the code reader. if you are skilled enough to diagnose the problem from the error code and then fix it, good for you. otherwise you still gotta go to the mechanic or dealer.

will cost you $88 for the diagnosis though.

[WaltGe]

It takes a lot more than a code scanner to fix the emissions system. You still need to be able to test the affected parts with some pretty sophisticated tools and have some knowledge to go with it. Cars today are more complex than spaceships were 40 years ago. A competent mechanic is still a good idea.

[doctorstork]

not too helpful...it is an infomercial for website...production nice though

[DeeeJayThrash]

fix the problem then disconnect the battery for about 30 min worked for me.

[cencal559jm]

@DeeeJayThrash ya but how you gona no what to look for without knowing the DTC code????????

[DeeeJayThrash]

IF your a true Automotive tech you would know how to use O-Scopes and know How An O scope Pattern should look like then you shouldn't have a problem. DTC only give you a Foundation to start diagnosing doesn't tell you the true problem IE. A car came to me with

[DeeeJayThrash]

check engine light on had several codes,Temp sensor voltage high, Rad Fan Relay circuit High, TStat Not Functioning, (Fuel trim)system Too rich, what are you gonna do with all of these codes ??. . . these codes aren't gonna tell you whats wrong you still have to do the full diagnostic, the actual problem with this car was a bad temp sensor when the ECM/ECU detected this it went into Limp-Home Mode made the engine run at a

[DeeeJayThrash]

richer mixture cuz a rich burn means cooler operating temp fans were always on to prevent overheating and since it was running at a lower operating temp the thermostat wasn't working correctly my point is your not gonna always need a scan tool sometimes it will cause more confusion than actually offering help.

[PACER2320]

@DeeeJayThrash my bmw had a trouble code. tried the battery trick didnt work then had to replace battery light still on. bought obd ii and cleared code. was told after a while code will come back on. dont know if thats true hasnt come on again but if it does will just clear code again. now that i know thats all it takes when i go and buy a used car ill take my obd ii with me to see if theyve done the same thing.

[DeeeJayThrash]

@PACER2320 why clear it and leave it, fix the problem now before it becomes something very costly

[PACER2320]

@DeeeJayThrash poor people have poor ways

[raguspag55]

@PACER2320 Yea hot shot, Im sure you drive your 1966 ford fairlane to your local dealer for a tune up. STFU , you must be a poor ass mechanic that hates it when people figure things out for themselves

[raguspag55]

@DeeeJayThrash no one clears it without fixing it, duh

[dawn200128]

@DeeeJayThrash sure ok, but how do you know what the problem is?????

[greenfeld5]

@DeeeJayThrash thank .this good tip

[K8driver]

Wow that's all huh just scan and fix. That's gotta be why I payed 20 grand to go to school for automotive for a year and a half. I guess I wasted my money now that everyone knows our secret.

[Blizzardnz]

use a paper clip its cheaper than buying a scanner

[Knifed]

you cannot use that method on OBD2 cars (96+). Some Chrysler cars STILL have the key on/ key x off x times method, as late as 06, but otherwise you need a scanner.

[dawn200128]

@Knifed all 96 and newer cars sold in the usa have to have obd2 where a generic scan tool has to work on it.

[Cabinetmaker09]

@Blizzardnz and your paper click will tell you whats wrong?

[garys737]

mole hills made mountains;;;;;;;;;;;;;;;;;

[Duppen]

Can you use one of those on any car?

[k2500diesel]

any car 1996 or newer

[heneylale]

uhh... take it to a mechanic i didnt go to school for 2 years to become a technician to learn everything from your 2 minute video . dumbasssssss .............

[salemcripple]

This is why OBD1 is better. you don't even need a scanner (if you know what you're doing that is). Plus modifying the engine for more hp is much, MUCH easyer.

[k2500diesel]

ya... no dude sorry

[blackop555]

great video. lots to be learned from it

[legitimate007]

Awesome vid, 2carpros is the best autorepair site hands down

[cashflowrising]

Awesome Video,

I think these videos will be a good addition to the quality of help you already have on the website. Thank You for all the help

[hatchetman1605]

Great video, keep on producing them!

[DoctorHagerty]

Ken, you look great there, how about giving the OBDII port location for most cars ("should be able to be viewed from a kneeling position at the drivers door" is how the criteria was written)
