hello, after looking for any threads on the AWC and finding mostly issues with flashing lights, I have the issue of all lights constantly on. Tarmac is on, Gravel is on, and Snow is on. All lights are lit and button unresponsive. I have no idea where to start troubleshooting other than checking fluid and tracing electrical. I don't have time or money to rip take the dash apart or take it to dealership. Any guidance is appreciated.

 

look for ACD Pump fail

The only reasons for the AWC lights all on is the Pump ( Maybe the wiring or fuse ) not building pressure or an Broken ABS Ring or sensor or trouble with one of the sensors attached like Steering wheel and acceleration sensors ..

Best is to get the Code stored in the AWC Ecu to determine the Fault.

Look for a shop with an so called OBD Breakout Box.... Then connect Pin 1 and PIN 4 together and Switch ign on. The 3 Lights will start to blink in sequences of Long and Short flashes.... like Morse Code ( example LONG LONG LONG Short Short = Code number 32....and so on )
All stored codes will come after each other, after the last one they will loop again....
