Pinpoint Test Q: The Low Fuel Indicator Is Never On (Early Build, Non-Hybrid)

Normal Operation

The low fuel indicator illuminates based upon the Distance To Empty (DTE) calculation. The DTE is calculated internally by the Instrument Panel Cluster (IPC) from data received from the PCM and the hardwired fuel level input. When the IPC determines that the DTE reaches approximately one-eighth of a tank of fuel (80 km [50 miles]) or less, the fuel gauge indicates empty and the IPC turns on the low fuel message center indicator.

This pinpoint test is intended to diagnose the following:

- IPC



PINPOINT TEST Q: THE LOW FUEL INDICATOR IS NEVER ON (EARLY BUILD, NON-HYBRID)

-------------------------------------------------
Q1 CARRY OUT THE IPC DEALER TEST MODE


- Ignition ON.
- Enter the IPC dealer test mode.
- Scroll through the displays to display TELLTALE TEST and monitor the low fuel indicator.
- Does the low fuel indicator illuminate when in the dealer test mode and turn off when in normal operation mode?

Yes
GO to Q2.

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

-------------------------------------------------
Q2 CHECK THE DTE OPERATION


- Ignition ON.
- Access and observe the message center DTE displayed mileage.
- Does the DTE display indicate 80 km (50 miles) or less until empty?

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

No
The system is operating correctly at this time. The low fuel warning message does not appear until the DTE is 80 km (50 miles) or less.
