Fault - ABS and
Traction Control warning light comes on in wet weather.
For the past two years when driving in very wet weather the ABS and Traction
Control warning lights have illuminated/flickered for some minutes before
This only occurred when driven through surface water, and the lights were
always off the next day. I assumed that it was a rear ABS sensor (since the rear
sensors are used both by the ABS and the Traction Control systems,) but because
the fault always cleared I did not pursue it.
Recently the ABS wiring was disturbed during work on the PAS pipe
replacement, after which the ABS light came on. This was investigated, and my
technician found that the multiplug leading to the ABS module (in the engine bay
low down on the offside Macpherson strut turret) had made a poor connection. He
stated that the multiplug was low enough to be affected by spray, and was
further dried by heat from the exhaust manifold and because of this the fault
might occur on other Scorpios.
He used water-repellant electrical grease on the multiplug and this has
cleared the symptom
