2012 Equipe - ABS warning but no codes

[mikeryantipp]

Hi all. I hope someone can help.

I had been getting an ABS warning before Xmas so my mechanic replaced the rear ABS loom and one speed sensor. I think he cleaned the other sensor (not 100% on this). All was OK up until this week and now the ABS warning is appearing again. When I connected my code scanner there are no codes on the ECU. I am using a Bluetooth OBD reader and the Torque app on my phone. I had expected to see a code telling me that the other sensor was now faulty.

Does anyone know if the ABS warning should generate a code and if so how can this be read?

ABS or Stability usually doesnt throw up a code. when mine came up it was my ABS Loom. others its the wheel sensors... others should be able to help.. i know some have had the ABS come up with a other connected fault.. i use dashcommand.. better than torque.

Thanks mate. I should also mention that I get a vibration/grinding through the brake pedal just before the warning comes on. Its as if for some reason the ABS engages itself and then realises something is wrong so it turns off the ABS and the warning appears. As I have had the loom and one sensor replaced I think it is the other sensor but it would be great if a code had been generated to confirm this.

cheap scan tools cannot read other module codes on many cars
only ecu codes

If I had of known last week,
I would of taken my Scanner with me and would of scanned it for you,
As I was in Ballarat for a day last week working.

Maybe try Supercheap and see if they can scan it.

The grinding / pulsing through the brake pedal is a give away for an ABS sensor (Brake sensor) the car thinks you have one wheel locked up, the code only seem to show up if it is active at the time, I had mine play up intermittently for months but I couldn't get a code out of it until it became permanent.

Thanks mate. What code reader do you use or recommend?

A former Holden dealer, or someone with a Tech 2.

Thanks everyone for the feedback. My mechanic replaced the other ABS sensor and the issue seems to have been resolved (for now).

Sorry for the late reply, [just catching up on messages][plenty of time to do it for the next 5 days of lockdown]
