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.

Yes
Troubleshooting completed.
No
Go to the next step.
2
• Start the instrument cluster input/output check mode.
• Select the check code 22.
• Display value is 7-206?
Yes
Go to the next step.
No
Go to Step 4.
3
• Perform the check code 23 inspection.
• Is there any malfunction?

- 2R terminal-GND
- 2T terminal-GND
• Is there continuity?
Yes
Repair or replace the wiring harness between the instrument cluster and GND.
No
Go to the next step.
7
• Turn the ignition switch off.
• 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
Repair or replace the terminal.
8
• Turn the ignition switch to LOCK position.
• Inspect for continuity following the wiring harness between instrument cluster and fuel gauge sender unit.
- 2R terminal-C terminal
- 2T terminal-A terminal
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness between the instrument cluster and the fuel gauge sender unit.
9
• Turn the ignition switch off.
• Is the fuel gauge sender unit installed properly?
Yes
Inspect the fuel gauge sender unit.
