Pinpoint Test H: The Odometer Is Inoperative

Normal Operation

The Instrument Panel Cluster (IPC) receives the odometer rolling count data from the PCM (non-hybrid) or the Transmission Control Module (TCM) (hybrid) over the High Speed Controller Area Network (HS-CAN) communication bus. The IPC monitors the odometer rolling count input and commands the odometer with a display in the message center display area.

If the IPC does not receive the odometer rolling count data or if the rolling count data is deemed invalid for less than 5 seconds, the IPC displays the mileage based upon the last known good input.

If the IPC does not receive the odometer rolling count data or if the rolling count data is deemed invalid from the PCM for 5 seconds, the IPC sets DTC U0100:00 (non-hybrid) or U0101:00 (hybrid) in continuous memory and defaults the odometer display to all dashes (-----).

If the Non-Volatile Memory (NVM) is corrupted, the message center displays ERROR.

NOTE: If DTC U0100:00 is set in the IPC, other observable symptoms may be an inoperative speedometer, tachometer, temperature gauge.

This pinpoint test is intended to diagnose the following:

- PCM (non-hybrid)
- TCM (hybrid)
- IPC



PINPOINT TEST H: THE ODOMETER IS INOPERATIVE

-------------------------------------------------
H1 CHECK FOR CORRUPTED NVM


- Ignition ON.
- Observe the message center display area.
- Does the odometer display ERROR?

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

No
GO to H2.

-------------------------------------------------
H2 RETRIEVE THE RECORDED DTCs FROM THE PCM AND TCM KOEO SELF-TEST


- Check for recorded PCM and TCM DTCs from the Key ON Engine OFF (KOEO) self-test.
- Are any DTCs recorded?

Yes
DIAGNOSE all PCM and TCM DTCs first. REFER to Computers and Control Systems Information.

No
GO to H3.

-------------------------------------------------
H3 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST


- Check for recorded DTCs from the IPC self-test.
- Are any DTCs recorded?

Yes
For DTC U0100:00 (non-hybrid), GO to Pinpoint Test BF. Pinpoint Tests BF: DTC U0100:00

For DTC U0101:00 (hybrid), GO to Pinpoint Test BG. Pinpoint Tests BG: DTC U0101:00

For DTC U0401:68 (non-hybrid) or U0402:68 (hybrid), RETRIEVE and REPAIR all non-network DTCs in the PCM and other modules on the network. REFER to Computers and Control Systems Information and Body Control Systems for a list of all DTCs.

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

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