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 (Instrument Panel Cluster) monitors the odometer rolling count input and commands the odometer with a display in the message center display area.
If the IPC (Instrument Panel Cluster) does not receive the odometer rolling count data or if the rolling count data is deemed invalid for less than 5 seconds, the IPC (Instrument Panel Cluster) displays the mileage based upon the last known good input.
If the IPC (Instrument Panel Cluster) 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 (Instrument Panel Cluster) 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 (Instrument Panel Cluster) , other observable symptoms may be an inoperative speedometer, tachometer, temperature gauge.
This pinpoint test is intended to diagnose the following:
- PCM (non-hybrid)
- TCM (Transmission Control Module) (hybrid)
- IPC (Instrument Panel Cluster)
PINPOINT TEST H : THE ODOMETER IS INOPERATIVE
H1 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 H2.
H2 RETRIEVE THE RECORDED DTCs FROM THE PCM AND TCM (Transmission Control Module) KOEO (Key ON Engine OFF) SELF-TEST
- Check for recorded PCM and TCM (Transmission Control Module) DTCs from the Key ON Engine OFF (KOEO) self-test.
Are any DTCs recorded?
Yes
DIAGNOSE all PCM and TCM (Transmission Control Module) DTCs first. REFER to Computers and Control Systems Information.
No
GO to H3.
H3 RETRIEVE THE RECORDED DTCs FROM THE IPC (Instrument Panel Cluster) SELF-TEST
- Check for recorded DTCs from the IPC (Instrument Panel Cluster) self-test.
Are any DTCs recorded?
Yes
For DTC U0100:00 (non-hybrid), GO to Pinpoint Test BF. Pinpoint Test BF: DTC U0100:00
For DTC U0101:00 (hybrid), GO to Pinpoint Test BG. Pinpoint Test 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 (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.
