Pinpoint Test G: The Odometer Is Inoperative

Normal Operation

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

If the IC does not receive the odometer rolling count data from the PCM/TCM for more than 5 seconds, the IC sets DTC U0100 (non-hybrid) or U0101 (hybrid) in continuous memory and defaults the odometer display to all dashes (-----).

If the IC receives invalid data for more than 5 seconds, the IC sets DTC U2200 and defaults the odometer display to all dashes (-----).

NOTE: If DTC U0100 is set in the IC, other observable symptoms may be an inoperative speedometer, tachometer or temperature gauge (non-hybrid).

- DTC B2143 (NVM Memory Failure) - a continuous and on-demand DTC that sets if the IC Non-Volatile Memory (NVM) is corrupted. If the IC determines the NVM to be corrupt, the IC sets DTC B2143 and displays ERROR in the Vacuum Fluorescent (VF) display (base cluster) area or message center (message center cluster).

This pinpoint test is intended to diagnose the following:

- PCM (non-hybrid)
- TCM (hybrid)
- IC


PINPOINT TEST G: THE ODOMETER IS INOPERATIVE

-------------------------------------------------
G1 RETRIEVE THE RECORDED DTCs FROM THE IC SELF-TEST

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

Yes
For DTC U0100, GO to Pinpoint Test AV. Pinpoint Tests AV: DTC U0100

For DTC U0101, GO to Pinpoint Test AW. Pinpoint Tests AW: DTC U0101

For DTC B2143, INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.

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

No
GO to G2.

-------------------------------------------------
G2 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 PCM or TCM DTCs recorded?

Yes
REFER to Computers and Control Systems Information.

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