C1210 - G SENSOR INPUT CIRCUIT PERFORMANCE






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

- When Monitored:
After initialization.

- Set Condition:
The voltage of the G-Sensor is out of range < 0.48 volts or > 4.82 volts.






DIAGNOSTIC TEST

1. (B24) G-SENSOR SUPPLY CIRCUIT OPEN






1. Turn the ignition off.
2. Disconnect the Anti-Lock Brake Module harness connector.
3. Disconnect the G-Sensor harness connector.

Note: Check connector-clean/repair as necessary.

4. Measure the resistance of the (B24) G-Sensor Supply circuit from the G-Sensor harness connector to the Anti-Lock Brake Module.

Is the resistance above 5 ohms?

Yes
- Repair the open (B24) G-Sensor Supply circuit.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test


No
- Go To 2.

2. (B24) G-SENSOR SUPPLY CIRCUIT SHORTED TO GROUND






1. Measure the resistance of the (B24) G-Sensor Supply circuit from the G-Sensor harness connector to ground.

Is the resistance below 5 ohms?

Yes
- Repair the (B24) G-Sensor Supply circuit shorted to ground.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Go To 3.

3. (B22) G-SENSOR SIGNAL CIRCUIT OPEN






1. Measure the resistance of the (B23) G-Sensor Signal circuit from the G-Sensor harness connector to the Anti-Lock Brake Module.

Is the resistance above 5 ohms?

Yes
- Repair the open (B23) G-Sensor Signal circuit.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Go To 4.

4. (B23) G-SENSOR SIGNAL CIRCUIT SHORTED TO GROUND






1. Measure the resistance of the (B23) G-Sensor Signal circuit from the G-Sensor harness connector to ground.

Is the resistance below 5 ohms?

Yes
- Repair the (B23) G-Sensor Signal circuit shorted to ground.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Go To 5.


5. (B924) G-SENSOR RETURN CIRCUIT OPEN






1. Measure the resistance of the (B924) G-Sensor Return circuit from the G-Sensor harness connector to the Anti-Lock Brake Module.

Is the resistance above 5 ohms?

Yes
- Repair the open (B924) G-Sensor Return circuit.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Go To 6.


6. (B924) G-SENSOR RETURN CIRCUIT SHORTED TO GROUND






1. Measure the resistance of the (B924) G-Sensor Return circuit from the G-Sensor harness connector to ground.

Is the resistance below 5 ohms?

Yes
- Repair the (B924) G-Sensor Return circuit shorted to ground.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test

No
- Replace the G-Sensor.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test
