Pinpoint Test AW: DTC U3010:01

Normal Operation
- DTC U3010:01 (Ignition Input Start: General Electrical Failure) - sets on-demand in the Instrument Panel Cluster (IPC) if the IPC detects voltage on the START input circuit during the self-test.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- IPC

PINPOINT TEST AW: DTC U3010:01

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

-------------------------------------------------
AW1 CHECK FOR VEHICLE OPTION CONTENT

- Check if the vehicle is equipped with Intelligent Access (IA).
- Is the vehicle equipped with IA?

Yes
GO to AW2.

No
GO to AW3.

-------------------------------------------------
AW2 CHECK THE RFA MODULE

- Ignition OFF.
- Disconnect: RFA Module C3503C.
- Ignition ON.
- Clear the IPC DTCs.
- Enter the following diagnostic mode on the scan tool: Self-Test.
- Repeat the IPC self-test.
- Is DTC U3010:01 recorded?

Yes
GO to AW4.

No
REFER to Starting System Testing and Inspection to diagnose the PCM starter inhibit function.

-------------------------------------------------
AW3 CHECK THE PCM

- Ignition OFF.
- Disconnect: PCM C175B.
- Ignition ON.
- Clear the IPC DTCs.
- Enter the following diagnostic mode on the scan tool: Self-Test.
- Repeat the IPC self-test.
- Is DTC U3010:01 recorded?

Yes
GO to AW4.

No
REFER to Starting System Testing and Inspection to diagnose the PCM starter inhibit function.

-------------------------------------------------
AW4 CHECK THE START INPUT CIRCUIT FOR A SHORT TO VOLTAGE

- Ignition OFF.
- Disconnect: IPC C220.
- Ignition ON.
- Measure the voltage between the IPC C220-9, circuit CDC54 (WH/GN), harness side and ground.




- Is any voltage present?

Yes
REPAIR circuit CDC54 (WH/GN) for a short to voltage. TEST the system for normal operation.

No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Service and Repair. TEST the system for normal operation.
