Record by record
2 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.
Component named as the cause
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

What the documents say to do
Unwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)Confirm
- The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.
Repair
- Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
- The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.
Caution
- Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.
Read the sentences of the record
- Fault
- AS VEHICLE IS SLOWING TO A STOP, THE ABS ENGAGES LIFTS THE BRAKE PEDAL, ESSENTIALLY ALLOWING THE VEHICLE TO ROLL FORWARD, AND REQUIRING A QUICK REACTION TO STRONGLY DEPRESS THE BRAKE PEDAL TO STOP THE VEHICLE.
- Cause
- THIS IS CAUSED BY A FAULTY AND CORRODED ABS SPEED SENSOR, WHICH HAS BEEN RECALLED ON THESE VEHICLES FROM 2002, BUT THE RECALL DOES NOT INCLUDE THE 2001 YEAR.
