xantia 1.9td abs light
I've heard you can test the wheel sensors at the plug to abs ecu, anyone got any info?
quick check!
ign. off disconnect ECU multiplug
resistance all 1000ohms
Front LH Pins 1 & 2
Front RH pins 19 & 20
Rear LH pins 5 & 6
Rear RH pins 22 & 23 Some models 21 & 23
Voltage AC 0.1V AC minimum while turning wheel
Front LH Pins 1 & 2
Front RH pins 19 & 20
Rear LH pins 5 & 6
Rear RH pins 22 & 23 Some models 21 & 23
if you have an oscillascope you can check for an AC waveform across the terminals
while turning wheel
This is a very simple check and unfortunately does not cover all faults!!
