Service Park Assist Message

[Habnixzuverliern]

Hi,
need help finding the problem with my Park Assist Module. I got the message in the dic, and read out the dtc and found out that i have random error messages, so i checked the cable and the cable are fine, so i bought 4 new sensors, no change, so i replaced the alarm module.
So now i am stucked, still have the problem, that i got random error messages, starts with shorting to ground or 12V or i got Bxxxx 08. Does somebody had the same problem? I can not find the problem, because it change depending on the installed combination.

Cheers.

youve spent enough money to buy a new house ,,,,and pay for real diagnoses ,,,,stop the bleeding and take to a garage that has service info for your 20XX veh ,,

 

good luck

I do not think you can simply change the sensors without having them re-calibrated unfortunately. Without calibration I am not sure what sort of error codes you might see. However, the dealer needs to hook up their diagnostic computer to do this and since the Tahoe (I am guessing that you're referring to the Tahoe from your other thread) isn't sold in Germany, this might be difficult.

hi,

 

you are right i spend enough money, but finding here a good Person who can help is a bit difficult. yes it is the Tahoe.

I tried but they cant help, the mechanic try to get into the car with there mdi tool, but no Chance. they used the wrong Software and at least the wrong car.

and some Chevrolet dealer dont know the car, they know the asia cars, so what should i say, i have to figure it out on my own.

I have Access to a tech2 and i cant find any calibration posiblity.

I am guessing this may not be the cause since you have errors present but do you have any sort of tow bar or anything else attached to the back bumper? The system is extremely sensitive to obstructions- in my Silverado it has given error messages in snow or even heavy rain.

Maybe there is a similar problem on your Tahoe.

Mike,

 

I have exactly the same problem when towing...even when Park Assist turned off it gives me a warning message...kinda stupid solution on the GMT900

Yes it is strange that a system on a vehicle designed to tow is not able to better deal with having a trailer on the back. When I moved to Michigan I saw that message every time I started up with the trailer on the truck.

 

 

Also rather jealous that you can get the G-class as a basic vehicle. I'm not sure when they started importing them to America but it's within the past 10-15 years and of course the ones sold here are only well-equipped with leather and such so they're horribly expensive.

Mine is from 1986 but the engine is a 5,5l V8 from the 1990´ ...that means no fu..... electronics...no ABS, no ESP etc. just an offroad fun toy...next few days gonna get rid of the sway bar in the front and the back for better articulation...

Hi,

 

Just a small update. I got 4 new sensors and harness. No dtc except from no communication to the radio.

I got now park assist off, with status inhibit, I don't know what this means, I hope somebody can help me.

 

Cheers.

So my last Problem is just, how to use a new Radio with new amp and pdc, i have a gmlan-01 module and it made sounds, but no pdc.

 

Does anyone have a solution for my last Problem.
