Diagnostic Test
1.
CHECK FOR DTC C102B–RIGHT REAR WHEEL SPEED SENSOR CIRCUIT
NOTE: This DTC must be active for the results of this test to be valid.
Turn the ignition on.
With the scan tool, record and erase DTCs.
Cycle the ignition switch from off to on.
With the scan tool, read DTCs.
NOTE: The Anti-Lock Brake Module must sense ALL 4 wheels at 12 km/h (7.5 mph) before it will extinguish
the ABS indicators.
Does the scan tool display: C102B–RIGHT REAR WHEEL SPEED SENSOR CIRCUIT?
Yes
>> Go To 2
No
>> The condition that caused the symptom is currently not present. Inspect the related wiring for a possible
intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
Refer to the ABS-INTERMITTENT CONDITION TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TEST-
ING)
2.
CHECK CONNECTOR/TERMINAL FOR DAMAGE
NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.
Turn the ignition off.
Inspect the Anti-Lock Brake Module harness connector, Right Rear WSS, and Right Rear WSS harness connector.
Is the Right Rear WSS or any of the connectors/terminals damaged?
Yes
>> Repair as necessary.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
