Pinpoint Test AD: The Low Fuel Warning Indicator Is Never/Always On

Normal Operation

The low fuel indicator turns on when the fuel level reaches a predetermined level, approximately 120 km (75 miles) (with a MyKey(TM) programmed key) or 80 km (50 miles) (with an administrator key). The low fuel level warning indicator and fuel gauge are controlled by the Instrument Panel Cluster (IPC) based on the fuel level data provided by the fuel pump module.

This pinpoint test is intended to diagnose the following:

- IPC (Instrument Panel Cluster)

PINPOINT TEST AD : THE LOW FUEL WARNING INDICATOR IS NEVER/ALWAYS ON

AD1 CHECK THE FUEL GAUGE FOR CORRECT OPERATION

- Ignition ON.

- Observe the fuel gauge operation.

Does the fuel gauge operate correctly?

Yes
GO to AD2.

No
GO to Pinpoint Test B Pinpoint Test B: Incorrect Fuel Gauge Indication.

AD2 CARRY OUT THE IPC (Instrument Panel Cluster) INDICATOR LAMP CONTROL ACTIVE COMMAND USING THE SCAN TOOL

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: IPC (Instrument Panel Cluster) DataLogger.

- Select the IPC (Instrument Panel Cluster) low fuel indicator (LOFUELL) active command. Command the low fuel indicator on and off. Observe the low fuel indicator.

Does the low fuel warning indicator illuminate when commanded on, and turn off when commanded off?

Yes
GO to AD3.

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

AD3 CHECK THE DTE (Distance To Empty) REMAINING MILEAGE DISPLAYED

- Ignition ON.

- Scroll through the information displays in the message center to the DTE (Distance To Empty) display.

Does the DTE (Distance To Empty) display indicate 120 km (75 miles) (with a MyKey(TM) programmed key) or 80 km (50 miles) (with an administrator key) or less?

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

No
The system is operating normally at this time. The fuel level must be below one-eighth tank before the low fuel indicator is turned on.
