VT ABS light

[IBLOWN]

Wife just called to say her '98 VT SS 5.0 ABS light came on.

No other lights were on unlike an ABS module problem. It doesnt have trac control though, so im unsure of the lights that come on with a non trac VT. I think from memory the ABS, Trac and oil lights come on with an ABS module fault?


So what about a non trac VT?

ABS Module issue can display many lights or a couple.

Could be a wheel sensor as well.

Hmmm, how do you know which wheel sensor lol?

tech 2 I would imagine, or check each one.

See if this item corresponds to your problem - should be easy enough for you to check out the lead:

LHF ABS Sensor - During excessive suspension movement while turning, the left front ABS sensor lead may contact the sway bar link rod. This can cause the lead to become damaged, stretched or disconnected. The ABS warning lamp on the instrument panel will illuminate if damage or disconnection occurs. A retaining clip was introduced late 1999 to limit the leads movement.

Yes, i found this yesterday. I'll have a look at it.

Have a look at this thread http://forums.justcommodores.com.au/vr-vs-holden-commodore-1993-1997/194507-abs-code-28-problem.html

Bridge pins 5 and 12 in the diagnostic connector to flash up ABS error codes on the ABS dashlight.
Heres a list of ABS/ETC error codes for VT to VY, but these codes can only be flashed up by bridging the terminals 5 and 12 on VT and VX models, for other models, you will need a suitable scantool to read these codes.

Code 12= Start up code/ system ok.
Code 21= Front right wheel speed sensor faulty signal.
Code 23= Front right wheel speed sensor short or open circuit.
Code 25= Front left wheel speed sensor faulty signal.
Code 27= Front left wheel speed sensor short or open circuit.
Code 28= Front wheel speed sensor frequency incorrect.
Code 31= Rear right wheel speed sensor faulty signal.
Code 33= Rear right wheel speed sensor short or open circuit.
Code 35= Rear left wheel speed sensor faulty signal.
Code 37= Rear left wheel speed sensor short or open circuit.
Code 41= Front right inlet valve solenoid.
Code 42= Front right outlet valve solenoid.
Code 45= Front left inlet valve solenoid.
Code 46= Front left outlet valve solenoid.
Code 47= Priming valve solenoid.
Code 48= Switching valve solenoid.
Code 51= Rear right inlet valve solenoid.
Code 52= Rear right outlet valve solenoid.
Code 55= Rear axle inlet valve solenoid/Rear left inlet valve solenoid.
Code 56= Rear Rear axle outlet valve solenoid/Rear left outlet valve solenoid.
Code 61= Pump motor or relay faulty.
Code 62= RPM signal incorrect.
Code 63= Valve solenoid relay circuit faulty.
Code 67= Stop light switch circuit faulty.
Code 71= Control module internal fault.
Code 72= Data fault.
Code 73= Requested torque circuit fault.
Code 74= Actual torque circuit fault.
Code 78= Incorrect optional coding.
Code 85= Voltage too low.

Code 58 for gen 111= Throttle relaxer PWM interface fault.
Code 62 for gen 111= RPM signal fault.
Code 64 for gen 111= Throttle relaxer control module position fault.
Code 65 for gen 111= Throttle relaxer motor fault.
Code 66 for gen 111= Throttle relaxer control fault.

You da man Brett, I don't care what they say about you!

Ah, let em say what they like, I guarantee most of em wouldnt say it to my face hehe.
