Solution

1. Preparation

Gather tools and parts required for the reset procedure.
Tools Required: OBD-II scanner, multimeter, socket set, and flat-head screwdriver.
Safety Warnings: Ensure the vehicle is parked on a level surface and the ignition is off before starting.

2. Disconnect Battery

Disconnect the negative battery terminal using a socket wrench to prevent any electrical issues during the reset process.

3. Reset the Instrument Cluster

Reconnect the battery terminal.
Turn the ignition switch to the "ON" position without starting the engine.
Wait for approximately 10 seconds to allow the gauge sweep to complete, indicating the cluster is resetting.
Turn the ignition off and then back to the "ON" position to finalize the reset.

4. Inspect and Test Fuel Sending Unit

If the gauge does not reset properly, remove the fuel tank access panel or the fuel tank (if necessary) to access the fuel sending unit.
Use the multimeter to test the resistance of the fuel sending unit. If it reads outside the manufacturer’s specifications, replace the sending unit.
Reinstall the fuel tank and access panel, ensuring all connections are secure.
