C2115-DYNAMICS SENSOR SUPPLY VOLTAGE HIGH

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

When Monitored:
Upon ignition on, prior to switching the (G4) Dynamics Sensor Supply circuit power on.
Set Condition:
If the Anti-Lock Brake Module detects voltage on the (G4) Dynamics Sensor Supply circuit when the circuit's power is turned off.

Possible Causes
WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
(G4) DYNAMICS SENSOR SUPPLY CIRCUIT SHORTED TO VOLTAGE
ANTI-LOCK BRAKES MODULE

1. VERIFY DTC IS ACTIVE

1.	Turn the ignition on.

2.	With the scan tool, read and record the ABS 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 ABS DTCs.

5.	Cycle the ignition switch.

6.	With the scan tool, read the ABS DTCs.

Does this DTC reset?

Yes

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

3. CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE

1.	Disconnect the Anti-Lock Brake Module harness connector.

2.	Turn the ignition on.

3.	Measure the voltage of the (G4) Dynamics Sensor Supply Circuit.

Is the voltage above 0.2 volts?

Yes

Repair the (G4) Dynamics Sensor Supply Circuit for a short to voltage.
Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).

Replace the Anti-Lock Brake Module in accordance with the Service Information.
Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).
