9N3 ABS Module Unable to Communicate

Post by lozza123 »

Hi,

Recently bought a 9N3 as a bit of a project, the main problem being there was an ABS light on, with a power steering light and an airbag light too. The garage ran some diagnostics on it and told me there was an ABS module issue, as it wasn't able to communicate with their software. I sent the module off to ECU Testing for a rebuild, and they said there wasn't anything wrong it it.

I've checked all fuses and made sure they're all in the right position.

Am I right in thinking there's a problem in the main loom?

Any help would be greatly appreciated.

TIA

For a good module to communicate, you'll need power, canbus and grounds.
