C2114-16-DYNAMICS SENSOR SUPPLY VOLTAGE - CIRCUIT VOLTAGE BELOW THRESHOLD





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

- When Monitored:
With the ignition on.

- Set Condition:
The Anti-lock Brake System (ABS) Module or the Dynamic Sensor has detected that the Dynamic Sensor Voltage is below 6.5 volts.





1. VERIFY THE DTC IS ACTIVE
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. (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR VOLTAGE




1. Turn the ignition off to the lock position.
2. Disconnect the Dynamics Sensor harness connector.
3. Turn the ignition on, engine not running.
4. Measure the voltage of the (G4) Dynamics Sensor Supply Circuit in the Dynamics Sensor harness connector.

Is the voltage below 10 volts?

Yes

- Go To 3

No

- Go To 5

3. (G4) DYNAMICS SENSOR SUPPLY CIRCUIT SHORTED TO GROUND




1. Turn the ignition off to the lock position.
2. Disconnect the ABS Module harness connector.
3. Measure the resistance between ground and the (G4) Dynamics Sensor Supply circuit at the Dynamics Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Go To 4

No

- Repair the (G4) Dynamics Sensor Supply circuit for an open or high resistance.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

4. (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR OPEN OR HIGH RESISTANCE




1. Measure the resistance of the (G4) Dynamics Sensor Supply circuit between the ABS Module harness connector and the Dynamics Sensor harness connector.

Is the resistance above 5 Ohms?

Yes

- Repair the (G4) Dynamics Sensor Supply circuit for an open or high resistance.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

No

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

5. CHECK (G94) DYNAMICS SENSOR GROUND CIRCUIT FOR OPEN OR HIGH RESISTANCE




1. Turn the ignition off to the lock position.
2. Using a 12-volt test light connected to B+, check the (G94) Ground Circuit in the Dynamics Sensor harness connector.

NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Replace the Dynamic Sensor. Dynamics Sensor - Removal.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

No

- Repair the (G94) Dynamics Sensor Ground circuit for an open or high resistance.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.
