Service 4WD and no DTC codes?
My '06 is reporting 'Service 4WD system' in the EVIC display. I checked via OBD (torque & bluetooth) and using the ignition-switch-three-times. No DTCs.
The ABS light is lit, as is the traction control light. I've begun to suspect my clockspring as it'd been having some intermittent horn issues.
My question is it unusual for it to report Service 4WD without there being ANY other codes?
