Pinpoint Test J: The Odometer Is Inoperative

Normal Operation

The Instrument Panel Cluster (IPC) receives the odometer rolling count data from the PCM over the High Speed Controller Area Network (HS-CAN). The IPC (Instrument Panel Cluster) monitors the odometer rolling count input from the PCM and commands the odometer with a display in the message center.

If the IPC (Instrument Panel Cluster) does not receive the odometer rolling count data from the PCM for more than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0100:00 in continuous memory and defaults the odometer display to all dashes (-----). If the odometer rolling count data is deemed invalid by the IPC (Instrument Panel Cluster), the IPC (Instrument Panel Cluster) sets DTC U0401:00 and defaults the odometer display to all dashes (-----).

If the Non-Volatile Memory (NVM) becomes corrupted or if a NVM (Non-Volatile Memory) failure occurs, the IPC (Instrument Panel Cluster) sets DTC U3000:44 and displays ERROR in the message center display.

NOTE: If DTC U0100:00 sets in the IPC (Instrument Panel Cluster), other observable symptoms may be an inoperative speedometer, tachometer, temperature gauge.

This pinpoint test is intended to diagnose the following:

- PCM

- IPC (Instrument Panel Cluster)

PINPOINT TEST J : THE ODOMETER IS INOPERATIVE

J1 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO (Key ON Engine OFF) SELF-TEST

- Check the recorded PCM DTCs from the Key ON Engine OFF (KOEO) self-test.

Are any DTCs recorded?

Yes
REFER to Computers and Control Systems Information.

No
GO to J2.

J2 CHECK FOR CORRUPTED NVM (Non-Volatile Memory)

- Ignition ON.

- Observe the message center display area.

Does the odometer display ERROR?

Yes
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) Service and Repair. TEST the system for normal operation.

No
GO to J3.

J3 RETRIEVE THE RECORDED DTCs FROM THE IPC (Instrument Panel Cluster) SELF-TEST

- Check for recorded IPC (Instrument Panel Cluster) DTCs from the self-test.

Are any DTCs recorded?

Yes
For DTC U0100:00, GO to Pinpoint Test AQ. Pinpoint Test AQ: DTC U0100:00

For all other DTCs, REFER to DTC Charts. Instrumentation, Message Center and Warning Chimes

No
INSTALL a new PCM. TEST the system for normal operation.
