S Type park brake - fault codes
I bought a 20072.7D S Type about 3 months ago (78k miles). The service history mentions aparkbrake fault being investigated in 2013 and 2015, on both occasions HA Foxreset the system and stated a new parkbrake module would be needed if ithappened again. No replacement parts were ever fitted.
I have had intermittent problems with the same fault since purchase, and newrear brake pads and a new battery have not cured it. Recalibration done ofcourse. The fault seems to be after driving the car from cold on short journeysof up to 5 miles, such as a school run. When returning to the car after, say,15 minutes, the fault appears and is able to be cleared by disconnecting thebattery for 10 seconds.
My indy mechanic has put it on diagnostics and found the following fault codes:
DTC ECU Description
1800-00 PBM Motor engage current reached before full apply travel distance
1802-00 PBM Motorengage current not reached or travelled too far on apply
Now I'm no expert, but the above faults seem to be the opposite of each other,so whats going on? I am told there is no problem with the wiring orcables and that it may be the parkbrake module or theparkbrake motor but neither could be identified as definitely theculprit.
So which part do I replacefirst?
