Diagnostic Procedure

FUEL GAUGE READING IS NOT CORRECT [INSTRUMENT CLUSTER] - DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	PERFORM CAN MALFUNCTION DIAGNOSIS AND DTC INSPECTION Perform the CAN malfunction diagnosis according to the recommendation of FOREWORD [INSTRUMENT CLUSTER]malfunction diagnosis, and if there is no CAN malfunction, perform inspection for DTCs. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Is the DTC displayed?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER] .)
1		No	Go to the next step.
2	INSPECTION OF INSTRUMENT CLUSTER Perform inspection of the fuel gauge/multi-information display referring to the instrument cluster inspection. (See INSTRUMENT CLUSTER INSPECTION .) Is the display normal?	Yes	Go to the next step.
2		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
3	DETERMINE IF MALFUNCTION CAUSE IS FUEL GAUGE SENDER UNIT Display the following BCM PIDs using the M-MDS. FUEL_SEN_M FUEL_SEN_S Verify the voltage in the display monitor while shaking the vehicle. Does the voltage change?	Yes	Go to the next step.
3		No	Go to Step 5.
4	DETERMINE IF MALFUNCTION CAUSE IS BCM Display the following instrument cluster PIDs using the M-MDS. FUEL_SEN_M FUEL_SEN_S Verify the resistance in the display monitor while shaking the vehicle. Does the resistance change?	Yes	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
4		No	Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION .)
5	INSPECT FUEL GAUGE SENDER UNIT Switch the ignition off. Inspect the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT INSPECTION [2WD] .) (See FUEL GAUGE SENDER UNIT INSPECTION [AWD] .) Is the fuel gauge sender unit normal?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the fuel gauge sender unit and the BCM. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the mid-wiring harness for a short to power supply. Repair or replace the wiring harness which has a malfunction. If there is no common connector: Repair or replace the wiring harness which has a malfunction.
5		No	Replace the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [2WD] .) (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [AWD] .)
