Possible cause

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].)
		No	Go to the next step.
2	INSPECTION OF INSTRUMENT CLUSTER •  Perform inspection of the fuel gauge/LCD display referring to the instrument cluster inspection. (See INSTRUMENT CLUSTER INSPECTION.) •  Is the display normal?	Yes	Go to the next step.
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
3	DETERMINE IF MALFUNCTION CAUSE IS FUEL GAUGE SENDER •  Display the following rear body control module (RBCM) 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.
		No	Go to Step 5.
4	DETERMINE IF MALFUNCTION CAUSE IS REAR BODY CONTROL MODULE (RBCM) •  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.)
		No	Replace the rear body control module (RBCM). (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION.)
5	INSPECT FUEL GAUGE SENDER UNIT •  Switch the ignition off (LOCK). •  Inspect the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT INSPECTION [2WD].) (See FUEL GAUGE SENDER UNIT INSPECTION [4WD].) •  Is the fuel gauge sender unit normal?	Yes	Refer to the wiring diagram and verify whether or not there is a mid-connector between the fuel gauge sender unit and the rear body control module (RBCM). If there is a mid-connector •  Determine the malfunctioning part by inspecting the mid-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 mid-connector •  Repair or replace the wiring harness which has a malfunction.
		No	Replace the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [2WD].) (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [4WD].)
