Abs Fault On Carina E From 1996

[DarkAge]

I've got a abs fault that wont go away.

Its on permanently as soon as i turn the key. All sensors are within 1-1.5kohm and all produce AC.

I've tried doing the ECU check (http://www.toyotaownersclub.com/forums/index.php?showtopic=47053) which doesn't thrown out any codes, the abs light is constantly lit:

"Always on" (no flash codes, just a steady light) — Malfunction of ABS module.

So where is the ABS module located and does anyone have the wiring diagram for the ABS module so I can troubleshoot ?

Thanks in advance

ABS computer is behind the glovebox, beside the engine computer. To access remove the glovebox by removing the hinge pins.

I also have an ABS fault & could do with the wiring diagram.

I've got fault 31, which is the right front wheel sensor.

I've changed the sensor & the computer but still get the fault.

I have fault code 31.

The right front sensor gives good AC & the wires back to the computer are good.

I've replaced the computer.

I still get the same fault.

Any ideas?

If you've managed to fix the fault you will need to clear the fault codes from the ECU. Connect E1 and Tc with short pin out, turn on ignition and pump the brake pedal 8 times within 3 seconds. After a further 3 seconds the ABS light should start to flash continuously. Turn off ignition. Remove jumper from E1 and Tc and replace short pin.

If all is OK your ABS light should now extinguish as expected. It may identify another problem or unresolved problem as soon as you turn the key, at which point, start all over again.

To clear the ABS fault light I found it easier just to briefly unplug the computer.

My problem was a damaged sensor ring. It looked like one of the teeth had been hit with a hammer.

I picked this up by doing the secondry test. To get the codes, after stopping the car as per instructions, I left the engine running & progressed with the rest of the steps. After doing this test it flashed two codes, the original 31 and 75.

So I removed the nut holding the CV & wheel, and pushed the CV out of the hub by about 20mm, allowing the sensor ring to be inspected properly. Damage was easily visible.

Previously I'd only inspected the ring through the small hole that the sensor fits through, and I'd missed the one damaged tooth.
