Pinpoint Test M: The Fuel Efficiency Gauge Is Inoperative (Hybrid)

Normal Operation

The Instrument Panel Cluster (IPC) receives the fuel usage data from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus. The IPC monitors the fuel usage inputs and provides an instantaneous display of the miles per gallon.

This pinpoint test is intended to diagnose the following:

- PCM concern
- Transmission Control Module (TCM) concern
- IPC


PINPOINT TEST M: THE FUEL EFFICIENCY GAUGE IS INOPERATIVE (HYBRID)

-------------------------------------------------
M1 VERIFY THAT THE IPC IS IN THE CORRECT DISPLAY SETTING

- Ignition ON.
- Using the setup menu, verify that the IPC is in the enlighten, engage or empower display mode.
- Is the IPC in the enlighten, engage or empower display mode?

Yes
GO to M2.

-------------------------------------------------
M2 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO SELF-TEST

- Check for 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 Information.

No
GO to M3.

-------------------------------------------------
M3 RETRIEVE THE RECORDED DTCs FROM THE TCM SELF-TEST

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

Yes

M4 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, GO to Pinpoint Test BF. Pinpoint Tests BF: DTC U0100:00

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

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.
