This is from a member's car I scanned this evening. His ABS / ASR lights are on. Anyone encountered this before? I've only seen 'ABS Wheel Speed Sensor 003 - Mechanical Failure' before, not 'ABS Wheel Speed Sensor 012 - Electrical Fault in Circuit'. Is it likely to be the ABS sensor itself / wiring / something else?

The wiki says what you'd expect...

Possible Causes

Open Circuit in Wiring from/to ABS Wheel Speed Sensor

ABS Wheel Speed Sensor faulty

Possible Solutions

Check Wiring from/to ABS Wheel Speed Sensor

Check ABS Wheel Speed Sensor

What I'm not clear on though is the relationship between the ABS 'Electrical Fault in Circuit' code and the Supply Voltage Terminal 30 codes. :wonder:

The electrics are designed to have a 12V supply, this at some point has dropped to 11.17V, which has caused the control units to log it. The word intermittent, tells me that this happened maybe just once. As a rule I tend to discount intermittent codes on the first scan, unless they crop up again after erasing and re-scanning. The data also tells you that the engine was not running at the time.

Your best course of action would be to check the wiring from the ABS sensor for any obvious signs of damage, if that checks out OK, connect a multi meter across the sensor terminals and take a resistance measurement or see if it produces a voltage when the wheel/hub is spun. I think that you have a faulty ABS sensor.

as per the previous post.

it looks like you only have an abs sensor issue, the other two could have been caused by the owner sitting in the car listening to the radio and so on without the engine running causing the battery voltage to drop significantly.

I am having the same problem in my yeti where both ABS and TCS lights are on. I also noticed that i get 3 long beeps while ignition after this issue happened, but that was intermittent.

I am from india and my car is just 7 months old and is under warranty. Right now the car is with service center from last one week. All i know it's G45 RHS sensor issue.

- The wheel speed sensor is already replaced.

- They checked the wiring and all fuse.

- They even replaced the wheel hub just to see if it's an issue with sensor ring.

However the issue still persist. What could be the real issue. can it be ABS unit at fault?

I am experiencing this atm and although my fault is reading on vcds as osf abs sensor I have replaced the abs sensors and hubs both sides (just for piece of mind) . Reset the faults yet it still persists and still no speedo reading and still abs/asr warning lights.

I'm now in the process of wiring tracing.

I have seen somewhere on here whilst Google searching that someone found dirt in a joint in the loom and that had worn through causing wires to make contact. I willtrace it and let you know my findings.

Oh I should point out I have checked the resistance on both sensors just to make sure they are both fine and they are.
