Hi!
When i start the car, everything is fine. No warning lights. As soon as i reach about 10 kph, the warning horn and light for the abs comes on along with the red warning light for the traction control. Should i clean the accelerometers or start diagnosing the abs sensors?
I have no acces to hammer tool.
Thanks!

I'm pretty sure Adrian's book describes the meaning of the different combinations; do you have a copy? (

This happened to me when one of the speed sensors on the wheels broke. It was an easy replacement, but the key is diagnosing which one of the 4 is bad.

When this happened to me I clean the accelerometers and that solve the problem.

In Adrian Streather's book has good instruction how to pinpoint problem.

Situation:
Start the engine: All the lights are ok. If i turn the **** for activating/deactivating PDAS the led turns on/off adn i can hear the diff locking up
If i disconect one of the accelerometers(yes i've cleaned these also) the abs or traction light are turning on. So these are working. If i start the engine with one of them disconnected i receive the red light award instantly
Moving the car: If i stay under 7km/h the car steers like s..t with the pdas activated or normal with it deactivated
As soon as i go over 7km/h the abs and traction light are on.
I changed the abs sensors, but no success.
Maybe the mechanic messed the wiring from the brake pads with abs sensors? Are the sockets interchangeable?
I have no chance to diagnose the car.
What should i do next?

I followed a fairly straight forward pin test on the abs module connector for resistance to each wheel sensor for a basic test of the abs sensors and wiring to the sensors, again suggest Adrian's book for this. Also there was some earth points to in front luggage compartment that are worth cleaning for ABS module.

i seem to remember another check was carried out by module once the car was moving too IIRC. Sure this was proving wave signal from ABS sensors in your hub.

Have you checked the brake fluid level?

Adrians book has a typo, when checking wheel sensors for resistance the front left is measured across pins 4 and 6 (not 4 and 5 as book states)
