As some of you may already know, I've been getting the ABS and TC light intermittently at startup, if I stop/start the engine, it usually stays away for the rest of the day.
Wabco ECU shows no faults, Motronic shows P1592 and no other faults.
Further digging on nanocom and I see the following with ignition on, engine on or off;
Rough road volts: cycling between 0v and 12v
Rough road status: ACTIVE
Rough running: ON
This means the Wabco ECU is indicating the vehicle is driving on a rough road.
If I open up ABS inputs, I see sensor volts and wheel speed indication all looking normal. In a straight line at low speed (before the diag mode cuts off) all sensors show the same speed.
I've checked connections on the Wabco ECU for corrosion, seems fine, despite showing no faults, i'm wondering if it is failing, at this point I can't see why rough road volts would be getting 12v. I'm tempted to take it out and see if I can look at the circuit board and components for damage/corrosion
