CHECK (B1) RIGHT REAR WSS SIGNAL CIRCUIT FOR A SHORT TO (B2) RIGHT REAR WSS 12 VOLT
SUPPLY CIRCUIT
Turn the ignition off.
Measure the resistance between the (B1) Right Rear WSS Signal circuit
and the (B2) Right Rear WSS Supply circuit.
Is the resistance above 5.0 ohms?
Yes
>>
Go To 10
No
>> Repair the (B1) Right Rear WSS Signal circuit and the (B2)
Right Rear WSS Supply circuit for a short together.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES -
STANDARD PROCEDURE).

RIGHT REAR WHEEL SPEED SENSOR
Replace the Right Rear Wheel Speed Sensor in accordance with the Service Information.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
WARNING: To avoid personal injury or death, check brake capability is available before road testing.
Road test the vehicle over 40 km/h (25 m.p.h.).
NOTE: Vehicle must be driven above 40 km/h (25 m.p.h.) for set conditions to be meet.
With the scan tool, read ABS 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.
Did DTC C102B–RIGHT REAR WHEEL SPEED SENSOR CIRCUIT reset?
Yes
>> Replace the Anti-Lock Brakes Module in accordance with the Service Information.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No

C1032-RIGHT REAR WHEEL SPEED SENSOR SIGNAL ERRATIC PERFORMANCE
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
With the ignition on.
•
Set Condition:
When the Right Rear WSS Signal is intermittently missing a vehicle speed above 25mph (40 kph) or erratic
wheel speed signal during acceleration or sensed wheel speed is different from other wheels.
Possible Causes
RIGHT REAR WSS AIR GAP FAULT
RIGHT REAR WSS LOOSE — B1, B2 CIRCUITS/CONNECTOR/TERMINAL DAMAGE
RIGHT REAR TONE WHEEL DAMAGE
RIGHT REAR WHEEL BEARING DAMAGE
IMPROPER RIGHT REAR TIRE PRESSURE/MISMATCHED TIRES
RIGHT REAR WSS

Diagnostic Test
1.
CHECK FOR DTC C1032-RIGHT REAR WHEEL SPEED SENSOR SIGNAL ERRATIC PERFORMANCE
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.
Road test the vehicle over 40 km/h (25 m.p.h.).
NOTE: Vehicle must be driven above 40 km/h (25 m.p.h.) for set conditions to be meet.
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: C1032-RIGHT REAR WHEEL SPEED SENSOR SIGNAL ERRATIC PERFOR-
MANCE?
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 RIGHT REAR WSS AIR GAP
Turn the ignition off.
Using a feeler gauge, measure the Right Rear WSS air gap.
NOTE: Refer to the appropriate service information, if necessary, for procedures or specifications.
Is the Right Rear WSS air gap within specifications?
Yes
>> Go To 3
No
>> Repair as necessary.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).

CHECK WHEEL SPEED SENSOR SIGNALS
Turn the ignition on.
With the scan tool, monitor and graph ALL the WSS speeds and compare graph while an assistant drives the vehi-
cle.
NOTE: If graph shows periodic dropouts pay close attention to the tone wheel.
Slowly accelerate as straight as possible from a stop to 40 km/h (25 m.p.h.).
Is the Right Rear WSS speed showing 0 km/h (0 m.p.h.) or not matching other wheel speeds?
Yes
>> Go To 4
No
>> Refer to the INTERMITTENT CONDITION diagnostic procedure.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
4.
CHECK FOR IMPROPER RIGHT REAR TIRE PRESSURE/MISMATCHED TIRES
Turn the ignition off.
Check and adjust the Right Rear Tire pressure.
Check and adjust all other tire pressures.
Inspect for mismatched tires on vehicle.
Is the Right Rear Tire improperly inflated or mismatched tires on vehicle?
Yes
>> Repair as necessary
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Go To 5
5.
CHECK RIGHT REAR WSS LOOSENESS, INSPECT B1, B2 CIRCUITS/TERMINALS FOR DAMAGE
NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals
Inspect the Anti-Lock Brake Module harness connector, Right Rear WSS, and Right Rear WSS harness connector
Inspect the Right Rear WSS for looseness, excessive corrosion and not properly fastened.
Inspect the (B1) Right Rear WSS Signal and (B2) Right Rear WSS Supply circuits between the Right Rear WSS
and Anti-Lock Brake Module for damage.
Is the Right Rear WSS loose or any of the wiring/connectors/terminals damaged?
Yes
>> Repair as necessary
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Go To 6
6.
CHECK RIGHT REAR TONE WHEEL FOR DAMAGE
Inspect the Right Rear Tone Wheel for damage, missing teeth, cracks, or looseness.
NOTE: The Tone Wheel teeth should be perfectly square, not bent, or nicked.
Is the Right Rear Tone Wheel damaged?
Yes
>> Repair as necessary
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
