It’s more that I don’t want the light on… Vehicle is already roadworthy.

Also what I thought was the ABS test port (without glasses on) was just a blue relay… so there really isn’t an ABS module.
I was wondering if the instrument panel might have its own CPU inside which is expecting an ABS module and lighting up because there isn’t one there, but surely it’s just a dumb panel...

Hmm ok seems there _is_ a CPU on the dash instruments…

I think I have found a solution - it involves putting a smalll piece of tape over the ABS light.
The worst type of hack, but perfect for this car...

Hi Guys,
I wasn’t happy with the tape, so I have decided to dig deeper.
In the electrical drawings, it shows that the ABS controller sends an ABS controller status signal to the instrument cluster in a RED/BLUE wire from plug E142 pin 14 to plug G92 Pin 10. My next plan of attack is to mimic the signal a working ABS controller sends to the instrument cluster at pin 10 on G92...
I was wondering if anyone knows (or can test on a vehicle with ABS) what the signal for ’STATUS OK’ is (i.e. ABS controller working, no faults) on PIN 10 of G92. It would be easy to assume it’s either 0v or 12V but given it’s a CPU output direct to another CPU, it could be 5v or a square wave or who knows…
Thanks guys!

actually first plan will be to pull apart the broken cluster and see if there is a jumper/solder connection that might be used when there is no ABS controller in which case I can just make the same modification to the new cluster.
I will let y’all know what I find.
