C2115-DYNAMICS SENSOR SUPPLY VOLTAGE HIGH





For a complete wiring diagram Refer to Diagrams/Electrical. Electrical Diagrams


- When Monitored:

Upon ignition on, prior to switching the (G4) Dynamics Sensor Supply circuit power on.

- Set Condition:

If the Anti-Lock Brakes Module detects voltage on the (G4) Dynamics Sensor Supply circuit when the circuit's power is turned off.








1. VERIFY DTC IS ACTIVE

Turn the ignition on.

With the scan tool, read and record ABS DTCs.

With the scan tool, read and record Environmental Data (EV Data).

With the scan tool, erase ABS DTCs.

Cycle the ignition switch.

With the scan tool, read ABS DTCs.

Does this DTC reset?

Yes

- Go To 2

No

- Perform the ABS Intermittent Condition diagnostic procedure. ABS Intermittent Condition Test
- Refer to the ABS-INTERMITTENT CONDITION TEST. ABS Intermittent Condition Test


2. INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORS

Turn the ignition off.

Check all related wiring for pinched, chafed, pierced, and partially broken wires.

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 SHORT FOR A SHORT TO VOLTAGE





Disconnect the Anti-Lock Brakes Module harness connector.

Turn the ignition on.

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 ABS VERIFICATION TEST. ABS Verification Test

No

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