FRV: VSA and ABS intermittently on

Hi there,

Any advice on the above? 

2006 Honda FRV 2.2 crdi with 110000 miles. 

We have come back from a long journey and VSA and ABS lights suddenly came on. Not doing anything particular at the time. Drove the car a few miles, stopped and restarted it and the light went away. 

Drove normally, no problems but then this happened again several times.

I knew we had a problem anyway with the brakes as pads were low by the time we got back and have had it at the garage for a caliper replacement  on the rear offside wheel as well as new pads, which needed changing. The caliper had been sticking a bit and hoped that might fix the VSA issue. However it hasn't. 

I did a 200 mile trip yesterday, on the way we had the VSA/abs lights on with a similar pattern - drive 5 or 10 miles, no lights then all of a sudden they come on. No obvious triggers. No impact on driving the car. Then when you stop the car and restart the lights come up until you hit 10mph and they clear. Oddly though on the way home I did about 80 miles with no lights coming on at all.

 

I used an Autel code reader to read the code. This is "16-1 Permanent DTC - Right rear wheel speed sensor failure". I've cleared the code but it comes back if the VSA comes on.

 

I'm no mechanic but is this likely to actually be a speed sensor issue? It feels odd that it would be so intermittent, could something else be causing it to trigger and if so are there any easy/likely culprits? Thanks

A battery on its way out can trigger unexpected codes as charging a bad battery (which happens all the time the engine is running) can cause abnormal voltage fluctuations in the electrical system.

 

When this happened to mine though, there were two codes, one to do with the steering yaw rate sensor and another that explicitly said "battery voltage low". I've also had P0420 ostensibly about the catalytic converter but potentially it's also related to the battery issues.

Ah, that's interesting... it is a dodgy eurocarparts Lion battery. No codes about low voltage though.
