ABS fault causing passlock

Recommended Posts

Posted (edited)

So I have been having issues with my 2012 GMC Canyon 4x4. I had been getting the ABS fault and traction fault code pop up on my dash intermittently and then go away without any cause, but with it the last couple days it has gotten way worse to the point that as soon as I turn the truck on the codes come up and then the truck goes into passlock mode. Which isnt very fun driving without any gauges. It does not derate the vehicle just no gauges and no radio and also if I shut it off it will not turn on again. Once I disconnect the battery and reconnect it I am able to start the vehicle again. It has become very unreliable and I would love some insight as to what would be causing this issue. Any help is greatly appreciated. Thank you.

Got any codes anywhere?


It sounds like you might be losing power or ground somewhere.
