The reason the Autel scanner didn't work is because you need to turn the ignition on, press "ok" on the scanner to run the program (even scanner says "start", they actually meant "ok"), and THEN start the engine within 10 seconds of pressing "ok". Great video by the way. I'm messing with one of these as we speak.
@lakesautomotivediagnostics6509 I get the same P34C4 with rough idle and check engine light after changing the timing chain on my 2017 pathfinder. Will the Autel Scanner be able to relearn the intake valve motors and clear this.code
How much does it run in a shop to replace the timing chain? Ive been trying to diagnose what the noise is on the side of the timing chain. Im not sure if its the tension pulley or what. Do you have a video on what the noise sounds like when the timing is going bad?
@lakesautomotivediagnostics6509 thank you for your response. I'm trying to help a friend that really can't afford to fix if it's the timing chain and also can't afford to lose transportation. When the time goes out what was your experience of finding out what the problem was?
Usually, you can hear the timing chain hitting the inside of the timing cover and you come also watch scan on a scanner and see the cams are not where they are supposed to be
@lakesautomotivediagnostics6509 can you hear it better with a stethoscope? The noise I hear I can't tell if it's a pulley or the timing chain. I know they have an appointment to have a shop put it on the computer and was hoping to get a better scan than what I can do. I already replace the camshaft sensors front and back on bank one. It threw a code of p0300, p0017, p34c5. I replaced the cam shift sensors and it threw a code a week later for the p0300 misfire.
All you had to do with the scan tool was click ok not starting the engine then when it went to the other screen start your engine and click start on the computer
