C0042-11-BRAKE PEDAL POSITION SENSOR - CIRCUIT SHORT TO GROUND





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

- When Monitored:
Ignition on.

- Set Condition:
When the Anti-lock Brake System (ABS) Module detects a short from the Brake Pedal Position (BPP) Sensor.





1. VERIFY THE DTC IS ACTIVE

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

1. Turn the ignition on.
2. With the scan tool, read and record the DTCs.
3. With the scan tool, read and record the Environmental Data to help identify the conditions in which the DTC was set.
4. With the scan tool, erase the DTCs.
5. Start the engine.
6. With the scan tool, read and record the DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- Perform the ABS-INTERMITTENT CONDITION TEST. Testing and Inspection.

2. (B237) BPP SENSOR SUPPLY CIRCUIT SHORTED TO GROUND




1. Turn the ignition off.
2. Disconnect the BPP Sensor harness connector.
3. Disconnect the ABS Module harness connector.
4. Measure the resistance between ground and the (B237) BPP Sensor Supply circuit in the BPP Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Go To 3

No

- Repair the (B237) BPP Sensor Supply circuit for a short to ground.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

3. (B137) BPP SENSOR SIGNAL CIRCUIT SHORTED TO GROUND




1. Measure the resistance between ground and the (B137) BPP Sensor Signal circuit in the BPP Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Go To 4

No

- Repair the (137) BPP Signal Signal circuit for a short to ground.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

4. (B937) BPP SENSOR RETURN CIRCUIT SHORTED TO GROUND




1. Measure the resistance between ground and the (B937) BPP Sensor Return circuit in the BPP Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Go To 5

No

- Repair the (B937) BPP Sensor Return circuit for a short to ground.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

5. (B137) BPP SENSOR SIGNAL CIRCUIT SHORTED TO (B937) BPP SENSOR RETURN CIRCUIT




1. Measure the resistance between ground and the (B937) BPP Sensor Return circuit and the (B137) BPP Sensor Signal circuit in the BPP Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Go To 6

No

- Repair the (B137) BPP Sensor Signal circuit and the (B937) BPP Sensor Return circuit for a short.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

6. BRAKE PEDAL POSITION (BPP) SENSOR
1. Replace the Brake Pedal Position (BPP) Sensor.
2. Perform the ABS VERIFICATION TEST. ABS Verification Test.

WARNING: To avoid possible serious or fatal injury, check brake capability is available before road testing.

3. Test drive the vehicle on mainly straight road conditions at a velocity between 15 and 35 km/h (9 and 22 mph).
4. With the scan tool, read the DTCs.

Does the DTC remain active?

Yes

- Replace the Anti-lock Brake System (ABS) Module. Powertrain Control Module - Removal.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

No

- Test complete.
