C2114

C2114-DYNAMICS SENSOR SUPPLY VOLTAGE LOW









When Monitored:

With the ignition on.

Set Condition:

When the Anti-Lock Brake Module indicates the operating voltage is out of specified range.






1. CHECK FOR A DTC C2114-SENSOR CLUSTER SUPPLY VOLTAGE LOW

NOTE: The Sensor Cluster is the same as the Dynamics sensor. 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 DTC's.
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 DTC's.
5. Cycle the ignition from off to on.
6. With the scan tool, read and record DTC's.

Does the scan tool display: C2114-SENSOR CLUSTER SUPPLY VOLTAGE LOW?

Yes

- Go To 2

No

- Perform the ABS-INTERMITTENT CONDITION diagnostic procedure.

2. CHECK THE WIRING HARNESS, TERMTNALS, AND CONNECTORS

1. Turn ignition off.
2. Check the Dynamics Sensor installation and torque of the mounting bolts.
3. Visually inspect the related wiring harness. Look for any bruised, chafed, pierced, or partially broken wires.
4. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.

Were any problems found?

Yes

- Repair as necessary.
- Perform the 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 of the (G4) Dynamics Sensor Supply circuit.

Is the voltacie above 10 volts?

Yes

- Replace the Dynamics Sensor.
- Perform the 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 Brakes 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 the 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 the ABS VERIFICATION TEST.

No

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