C2114

C2114-DYNAMICS SENSOR SUPPLY VOLTAGE LOW







- When Monitored:
With the ignition on.

- Set Condition:
If the Dynamics Sensor status changes from initialized to not initialized due to low voltage on the (G4) Dynamics Sensor Supply circuit.





1. VERIFY DTC IS ACTIVE

NOTE: The Sensor Cluster is the same as the Dynamics sensor.

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 ABS DTCs.
3. With the scan tool, read and record Environmental Data to help identify the conditions in which the DTC was set.
4. With the scan tool, erase the ABS DTCs.
5. Cycle the ignition switch.
6. With the scan tool, read the ABS DTCs.

NOTE: Attempt to operate the vehicle under conditions similar to which the DTC was set. It may be necessary to test drive the vehicle within the DTC monitoring and set conditions in order for this DTC to set.

Does this DTC reset?

Yes

- Go To 2

No

- Perform the ABS INTERMITTENT CONDITION TEST ABS Intermittent Condition Test.

2. INSPECT RELATED WIRING HARNESS, TERMINALS, AND CONNECTORS
1. Turn the ignition off.
2. Check all related wiring for pinched, chafed, pierced, and partially broken wires.
3. Check all related connectors for broken, bent, pushed out, and corroded terminals.

Were any problems found?

Yes

- Repair as necessary.
- Perform ABS VERIFICATION TEST ABS Verification Test.

No

- Go To 3

3. CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT AND (G94) DYNAMICS SENSOR GROUND CIRCUIT FUNCTION




1. Disconnect the Dynamics Sensor harness connector.
2. Turn the ignition on.
3. Measure the voltage between the (G4) Dynamics Sensor Supply Circuit and the (G94) Dynamics Sensor Ground Circuit.

Is the voltage above 10 volts?

Yes

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

No

- Go To 4

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




1. Turn the ignition off.
2. Disconnect the Anti-Lock Brake Module harness connector.
3. Measure the resistance of the (G4) Dynamics Sensor Supply circuit between the Dynamics Sensor harness connector and the Anti-Lock Brake Module harness connector.

Is the resistance below 5.0 ohms?

Yes

- Go To 5

No

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

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




1. Measure the resistance of the (G94) Dynamics Sensor Ground circuit between the Dynamics Sensor harness connector and the Anti-Lock Brake Module harness connector.

Is the resistance below 5.0 ohms?

Yes

- Replace the Anti-Lock Brake Module.
- Perform ABS VERIFICATION TEST ABS Verification Test.

No

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