I've just had a customer in with this vehicle who insisted on waiting whilst I carry out a diag test on the ABS, so I haven't been able to spend much time on it. I've told her to go away and have rebooked it when she can leave it with me.This gives me chance to do some home work.

I have ABS, traction control and hill decent lights on. They've been on for a few weeks. Diag test using Autodiagnos reports fault code 0114 - Pump monitor fault - present. I can't clear the code - obviously but an actuator test confirms that the ABS pump is working correctly.

Any tips on where I go from here?
