Pinpoint Test H: The Odometer Is Inoperative

Normal Operation

The odometer is displayed in the message center Vacuum Fluorescent (VF) display. The Instrument Cluster (IC) receives the odometer rolling count data from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus and displays the data in the odometer display area of the message center. If the IC does not receive the vehicle rolling count message from the PCM or the rolling count data is deemed invalid by the IC, the IC sets DTC U0100.

NOTE: If DTC U0100 is set in the IC, other observable symptoms are likely to be an inoperative speedometer, tachometer and temperature gauge.

This pinpoint test is intended to diagnose the following:

- PCM
- IC

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


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

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

No
GO to H2.

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


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

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

No
GO to H3.

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


- Check for recorded IC DTCs from the self-test.
- Is DTC U0100 recorded?

Yes
GO to Pinpoint Test AT. Pinpoint Test AT: DTC U0100

For DTC U2023, RETRIEVE and REPAIR all non-network DTCs in the PCM and other modules on the network. REFER to Computers and Control Systems and Multifunction Electronic Modules Diagnostic Trouble Code (DTC) Chart for a list of all DTCs.

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

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