NO. 1 FUEL GAUGE INDICATION IS INCORRECT [INSTRUMENT CLUSTER]

id0903d5005000

1	Fuel gauge indication is incorrect
POSSIBLE CAUSE	•  Fuel gauge sender unit malfunction •  Instrument cluster malfunction •  Connector or pin malfunction •  Fuel gauge sender unit is improperly installed •  Open or short circuit in wiring harness between instrument cluster and fuel gauge sender unit

Diagnostic procedure

STEP	INSPECTION		ACTION
1	•  Turn the ignition switch to the ON position. •  Verify that the fuel gauge needle does not move after ignition switch is turned off, or the display does not indicate F even though fuel tank is full. •  Is the fuel gauge normal?	Yes	Troubleshooting completed. (The system is normal.)
		No	Go to the next step.
2	•  Retrieve the DTC of instrument cluster using M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) •  Is the DTC detected?	Yes	Go to applicable DTC troubleshooting procedure. (See DTC TABLE [INSTRUMENT CLUSTER].)
		No	Go to the next step.
3	•  Inspect the instrument cluster. (See INSTRUMENT CLUSTER INSPECTION.) (See INSTRUMENT CLUSTER INSPECTION [MZ-CD 1.4 DI Turbo, MZ-CD 1.6 (Y6)].) •  Is the fuel gauge display normal?	Yes	Go to Step 7.
		No	Go to the next step.
4	•  Turn the ignition switch to LOCK position. •  Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). •  Are the terminals normal?	Yes	Go to the next step.
		No	Repair or replace the terminal.
5	•  Turn the ignition switch to LOCK position. •  Inspect for continuity following the wiring harness between instrument cluster and fuel gauge sender unit. ―  2T terminal—B terminal ―  2R terminal—D terminal •  Is there continuity?	Yes	Go to the next step.
		No	Repair or replace for open circuit in the wiring harness between the instrument cluster and the fuel gauge sender unit.
6	•  Turn the ignition switch to LOCK position. •  Remove the instrument cluster. •  Disconnect the instrument cluster connector. •  Inspect for continuity between the following wiring harness. ―  2R terminal—ground •  Is there continuity?	Yes	Repair or replace the wiring harness for short to ground.
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.) (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION [MZ-CD 1.4 DI Turbo, MZ-CD 1.6 (Y6)].)
7	•  Turn the ignition switch to LOCK position. •  Inspect the fuel gauge sender unit connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). •  Are the terminals normal?	Yes	Go to the next step.
		No	If the instrument cluster connector is poor connection: Connect the instrument cluster connector securely. If malfunction is in the instrument cluster side connector: Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.) (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION [MZ-CD 1.4 DI Turbo, MZ-CD 1.6 (Y6)].) If malfunction is in vehicle side connector: Repair or replace malfunctioning part.
8	•  Turn the ignition switch to LOCK position. •  Is the fuel gauge sender unit installed properly?	Yes	Inspect the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT INSPECTION.) (See FUEL GAUGE SENDER UNIT INSPECTION [MZ-CD 1.4 DI Turbo, MZ-CD 1.6 (Y6)].)
		No	Reinstall the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION.) (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [MZ-CD 1.4 DI Turbo, MZ-CD 1.6 (Y6)].)
