Volvo Owners Club Forum - View Single Post - 2007 XC90 Replaced ABS Sensor-DSTC Blinking with Power Loss

Evening,

I had DSTC and ABS lights on with Brake Assist Service Required message in my XC90. Scanned it and it was the faulty LF (left front) ABS sensor - no signal. Got the sensor replaced and cleared the codes.

No more lights or messages but when trying to move the car (going over 5mph) DSTC blinks with power loss and when stopping the car there is a kick-back in the pedal. So:

1. Tried driving turning DSTC OFF then the LF brake gets applied automatically-stopping the car moving.
2. Tried driving disconnecting the LF sensor - DSTC and ABS lights come on but car drives all fine
3.Checked the new sensor and the wires for any damages- nothing wrong externally.

Should brakes/ABS need aligning or calibrating..anything like that?

I'd highly appreciate if anyone could help me with this.

Zak
