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) . 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.
