Pinpoint Test P: The Low Fuel Warning Indicator Is Never/Always On
Normal Conditions
The low fuel indicator turns on when the fuel level reaches a predetermined level, typically 1/8 tank on or approximately 80 km (50 miles). The low fuel level warning indicator and fuel gauge are controlled by the IC based on the fuel level data provided by the fuel pump module.
This pinpoint test is intended to diagnose the following:
- IC
PINPOINT TEST P: THE LOW FUEL WARNING INDICATOR IS NEVER/ALWAYS ON
-------------------------------------------------
P1 CHECK THE FUEL GAUGE OPERATION
- Ignition ON.
- Observe the fuel gauge operation.
- Does the fuel gauge operate correctly?
Yes
GO to P2.
No
Go To Pinpoint Test A. Pinpoint Test A: Incorrect Fuel Gauge Indication
-------------------------------------------------
P2 CARRY OUT THE IC WARNING LAMPS AND CHIME ACTIVE COMMAND USING THE SCAN TOOL
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IC DataLogger.
- Select the IC low fuel indicator (LOFUELL) active command. Command the low fuel indicator on and off. Observe the low fuel indicator.
- Does the low fuel indicator illuminate when commanded on, and turn off when commanded off?
Yes
If equipped with a base cluster, GO to P3.
If equipped with a message center cluster, GO to P4.
No
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.
-------------------------------------------------
P3 CHECK THE FUEL LEVEL PERCENT INPUT USING THE IC DEALER TEST MODE
- Ignition ON.
- Enter Instrument Cluster (IC) Dealer Test Mode.
- NOTE: The display below uses xxx's to represent a numeric or alpha-numeric value. The value may display the same amount of characters represented by the xxx's or there may be more/less depending on the type of display. For example: FP xxx (base cluster) or FUEL LVL FILT/FLPS INPUT xxx (message center cluster) may display FP 85 or FUEL LVL FILT/FLPS INPUT 85.
- Scroll down to FP xxx (base cluster) or FUEL LVL FILT/FLPS INPUT xxx (message center cluster).
- Does the fuel level display 26 or less?
Yes
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.
No
The system is operating normally at this time. The fuel level must be below 1/8 tank before the low fuel indicator is turned on.
-------------------------------------------------
P4 CHECK THE DISTANCE TO EMPTY (DTE) REMAINING MILEAGE DISPLAYED
- Ignition ON.
- Scroll through the information displays in the message center to the DTE display.
- Does the DTE display indicate 80 km (50 miles) or less?
Yes
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.
No
The system is operating normally at this time. The fuel level must be below 1/8 tank before the low fuel indicator is turned on.
