Hi all ,
Just had a similar experience travelling in central Aust. Intermittent ABS, ESC and BAS lights were coming on, the off for a while as well as the old service 4WD system. After a while the lights were on permanently but the car was still OK to drive towing a 3t van. The other symptom was that each time the car was started the diffs would bind but free themselves after a short distance and then the service 4WD system alert would come on. After reading a few of Clarky's posts I suspected a wheel sensor problem. Had the codes read and the P73 update done in Alice Springs and the deeper codes read were, C1027 (LHR wheel speed sensor), C1043 (LHR tone wheel performance), C102A (LHR wheel speed comparative performance), C1407 (Transfer case brake control), C1418 (Front diff control circuit high), C1421 (Rear diff clutch performance), C2104 (Drive train supply voltage). Cruise control also didn't work which is not surprising.
Drove the car incident free down to Pt Lincoln where I had the LHR wheel speed sensor replaced at City motors. Surprisingly the genuine part was only $47 and 1.5hrs labour to fit. All now back to normal.
