Symptom List:

LEFT FRONT WHEEL SPEED SIGNAL FAILURE
LEFT REAR WHEEL SPEED SIGNAL FAILURE
RIGHT FRONT WHEEL SPEED SIGNAL FAILURE
RIGHT REAR WHEEL SPEED SIGNAL FAILURE

Test Note:

All symptoms listed above are diagnosed using the same tests.

The title for the tests will be LEFT FRONT WHEEL SPEED
SIGNAL FAILURE.

When Monitored and Set Condition:

LEFT FRONT WHEEL SPEED SIGNAL FAILURE

When Monitored:

Wheel speed are checked and verified at drive off and continuously

thereafter.

Set Condition:

If, during an ABS stop, the CAB commands any valve solenoid on for an

extended length of time, and does not see a corresponding wheel speed change, the
Diagnostic Trouble Code (DTC) is set. The DTC can also set if the signal is missing or
erratic.

LEFT REAR WHEEL SPEED SIGNAL FAILURE

When Monitored:

Wheel speed are checked and verified at drive off and continuously

thereafter.

Set Condition:

If, during an ABS stop, the CAB commands any valve solenoid on for an

extended length of time, and does not see a corresponding wheel speed change, the
Diagnostic Trouble Code (DTC) is set. The DTC can also set if the signal is missing or
erratic.
