Record by record
7 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.
Symptom
Component named as the cause
How it is said to have ended
- says it came back1
- says it did not fix it1
- result not stated2
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.

SUPPLEMENT TO 04094 FRONT WHEEL SPEED SENSOR CORROSION. *TT
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.

What the documents say to do
Brake pipe (brake line) corrosion and ruptureConfirm
- In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).
Repair
- GM recommends replacing the entire set of pipes whenever any pipe leaks or is corroded enough to need replacement.
- On June 28, 2013 GM released 66 new part numbers for servicing brake pipes in 1999-2007 GMT800 pickups and utility vehicles.
Caution
- Analysis of repair records indicates that consumers often elect to repair only the failed circuit.
