C1035 - RIGHT REAR WHEEL SPEED COMPARATIVE PERFORMANCE






For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on.

- Set Condition:
When the Right Rear WSS reading is different from the readings received from the other WSS's. The Anti-Lock Brake Module compares WSS readings from side-to-side on an axle and front-to-rear.






DIAGNOSTIC TEST

1. CHECK FOR DTC C1035 - RIGHT REAR WHEEL SPEED COMPARATIVE PERFORMANCE

Note: This DTC must be active for the results of this test to be valid.






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.

1. Turn the ignition on.
2. With the scan tool, record and erase DTC's.
3. Cycle the ignition switch from off to on.
4. With the scan tool, read DTC's.

Does the scan tool display: C1035 - RIGHT REAR WHEEL SPEED COMPARATIVE PERFORMANCE and C102B - RIGHT REAR WHEEL SPEED SENSOR CIRCUIT?

Yes
- Refer to C102B-Right Rear Wheel Speed Sensor Circuit for the related symptom(s). Refer to C102B
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test


No
- Go To 2.

2. CHECK WHEEL SPEED SENSOR SIGNALS






1. Turn the ignition off.
2. With the scan tool, monitor ALL the WSS speeds while an assistant drives the vehicle.
3. Slowly accelerate as straight as possible from a stop to 40 km/h (25 mph).

Is the Right Rear WSS Speed showing 0 km/h (0 mph) or not matching other wheel speeds?

Yes
- Go To 3.

2. Check and adjust the Right Rear Tire pressure.
3. Check and adjust all other tire pressures.
4. 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-VER 1. Refer to ABS Verification Test

No
- Go To 5.

5. CHECK RIGHT REAR TONE WHEEL FOR DAMAGE

1. Turn the ignition off.
2. 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-VER 1. Refer to ABS Verification Test

No
- Go To 6.

6. CHECK RIGHT REAR BRAKE HARDWARE DAMAGE

Is any brake lining, component, or hardware damaged?

Yes
- Repair as necessary.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Go To 7.

7. ANTI-LOCK BRAKE MODULE - INTERNAL FAULT






1. Turn the ignition off.
2. Replace the Right Rear WSS.
3. With the scan tool, erase DTC's.
4. Road test the vehicle over 40 km/h (25 mph).
5. Turn the ignition on.
6. With the scan tool, read DTC's.
