I got a fancy scan tool (Autel MaxiAP AP200 Bluetooth OBD2 Code Reader) that shows these codes on my Malibu 2.0 Premier:
Electronic brake control module fault
Active safety control module fault
Instrument cluster fault
Parking assist control module fault
Body control module fault
What do the above fault codes mean? What should I do?
It looks like U0151 and U0269 are not current, just in history. U0420 can happen during a remote start and there is a bulletin for it. Are you experiencing any problems with these systems? If not, I’d clear them and see if they return. If you have a warning light on or are getting problems don’t clear and take it in or get advice from others.
There are no warning lights. I cleared them all let’s see what happens. I got Autel AP200, It’s amazing for $60. It has one free generic code reader, but You need to pay $15 extra for each software. I got the GM software downloaded. It shows you all the information. I also got Mercedes Benz software for my wife. I was able to reset her airbag light with it.
U codes are data stream issues. I’ve found they can be random. If consistent usually a module P , B , etc. code failure will also be set. I think they come from spikes in the system as I’ve seen them random in my fleet. I get interior light codes from putting in LED’s in the dome lights.
