Hi. My 1998 Xantia has developed the dreaded "ABS Light on" fault. It won't talk to any diagnostic tools either. I have searched this forum for wiring information but have only found details of the 37 pin wiring connector on another ECU model. My ECU has a 25 pin connector on it. I'm sure there's a sensor fault cos I'm getting 1000 ohms between 3 pairs of pins (1 and 2; 5 and 6; 19 and 20). I don't know which pins the other sensor is connected to, nor which pins relate to which sensors. Does anyone out there have pin-out info for this kind of ECU? It's an Ate one, all black.
Many thanks
Ian
Xantia ABS Light (yet again!)

I've found the pinouts for the ECU: FNS = 1 and 2; RNS = 5 and 6; FOS = 19 and 20; ROS = 22 and 23. I'm reading 10Meg ohms on 22 and 23 so that's hopefully the problem. However.......
I have disconnected the sensor at the wheel plug and inserted a 1.1 kOhm resistor to trick the ECU into thinking there's a good sensor there. Still got the ECU light [:(] So do I have a dead sensor AND ECU? (Feel Sick!)
