Pinpoint Test J: The Low Fuel Warning Indicator Is Never On

Normal Operation

The low fuel warning indicator illuminates when the Instrument Panel Cluster (IPC) calculation for the Distance To Empty (DTE) reaches 50 miles (80 km) or less. The DTE (Distance To Empty) is calculated internally by the IPC (Instrument Panel Cluster) from data received from the PCM and the fuel gauge. If the IPC (Instrument Panel Cluster) detects a fault in the fuel input (circuitry or fuel pump module), the IPC (Instrument Panel Cluster) defaults the fuel gauge to the empty (E) stop position and illuminates the low fuel warning indicator.

This pinpoint test is intended to diagnose the following:

- IPC (Instrument Panel Cluster)

PINPOINT TEST J : THE LOW FUEL WARNING INDICATOR IS NEVER ON

J1 CARRY OUT THE IPC (Instrument Panel Cluster) INDICATOR LAMP 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 (LOFUELL) active command. Command the low fuel warning indicator on and off. Observe the low fuel warning indicator.

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

Yes
GO to J2.

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

J2 CHECK THE DTE (Distance To Empty) STATUS

- Access and observe the message center DTE (Distance To Empty) displayed mileage.

Does the DTE (Distance To Empty) display indicate 80 km (50 miles) or less until empty?

Yes
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) Service and Repair. 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 (Distance To Empty) is 80 km (50 miles) or less.
