NM35 ABS light

[MrStabby]

My ABS warning light comes on a few seconds after engine start. I've checked brake fluid level and fuses. What's next to troubleshoot this? I can read CEL codes but nothing ABS related comes up, however, i guess that may be just a limitation of the software.

You need to get a proper scan tool hooked up to the diag port and see what the ABS CU has to say for itself.

Damn. Anyone in Sydney have the right Consult?

[GTSBoy]

Doesn't have to be specifically "Consult".  Any workshop with a Snap-On or equivalent diagnostic handset should be able to do it.  I threw my bro-in-law's diag unit* on my car and saw the ECU, TCU and HICAS computer all available.  That was 20 years ago before the auto tranny fell out of it.

 

* Can't remember the brand.

Haven't managed to source decent diag handset yet...

New issue is that the ABS often runs constantly after the ignition is off/key removed. A bit of googling suggests this could be due to relay failure. Anyone know where the ABS relays are? Doesn't appear to be an ABS relay on the presentation near the battery. On the R32 GTR they're on the ABS unit itself, but unless they're really small i cant see them being on the M35 unit.
