Did you have BOTH of them jumpered at the same time? You have to complete the circuit thru the ABS sensor (VSS in the diagram) for the PSOM to get a signal.

If you DID, and the speedo didn't work, then it's not the 4WABS module - it's the sensor, the PSOM, or the wiring between them.

But I'll send it if you want - it's your property.

no i did not jumper them all at the same time. i will try that tomorrow then.

Don't jumper them ALL together. Jumper both pairs at the same time, but keep the 2 jumper wires separate from each other.

You can jumper 14 to EITHER 21 or 22, and jumper 39 to the other (doesn't matter which way). You're trying to get the ABS (VSS) signal from the sensor directly to the PSOM. Look at that diagram again.

Just for clarity: jumper 14 to 21, & 39 to 22 (low numbers, high numbers).

awesome, steve we are in business. jumping those like you said worked and the speedo was working properly. so the anti lock brake module is bad, so if you would please send that i would sure appreciate it.

thanks alot for your help.

It'll go in the mail Tuesday.

can i drive with the module out and just those pins jumped or would it be dangerous? my abs light was on before the module was pulled so i wonder if my abs worked properly to begin with?

thanks
Travis

Yes, you can drive. The ABS doesn't normally do anything anyway.

kemicalburns · 09-03-2007, 10:38 AM

Well thanks to steve83 for all his troubleshooting guidance and the anti lock brake module i was able to purchase from him. this has fixed both my speedo issue and now the abs light is off as well.

Thanks steve
