My 2000 90 series ABS, TRC, VSC and hand brake warning lights came on when I started the car when parked, not moving and the speedo now doesn't work. I have followed many methods suggested to read the ABS fault codes and re-set the lights but none of them work. I can re-set the ECU code (42 - vehicle speed signal) which I believe is a culmination of the ABS fault. Jumping Tc and E1 (CG) on the under-bonnet diagnostic port gives me the ECU code (similar with the OBD port under the dash) but I can't get the ABS light to blink out any fault codes.
I grounded the AB pin but then the Air Bag light comes on so I guess AB means Air Bag.
There is a plethora of info on the web re similar problems but for other Toyota models - mainly in the US and none of the suggested diagnostic methods seem to work for me.
I have removed each wheel speed sensor and cleaned them and cleaned up the mating surfaces to ensure proper clearance. Also checked that each sensor ring is clean, intact and still fastened to its rotor - all looks good to me here. I have traced all wheel sensor wiring and can't see any damage.
Does anyone have any suggestions how to get the ABS light to blink out the fault code ? I am going to test the ac voltage from each sensor this morning but it would be a little easier if I knew which one(s) was being reported as faulty.
