Tachometer Repair

Tachometer

NOTE: The needle of speedometer or tachometer may continue to rotate clockwise until it rests on the mask plate. If a customer complains of this concern, repair the needle position according to the following steps.




1. Verify the concern.
2. Turn the ignition switch to LOCK position.
3. Remove the ROOM fuse, then wait for 10 minutes or more until the power supply in the instrument cluster is spent.
4. Turn the ignition switch to ON position.




5. Verify that the needle returns to zero.
- After the needle returns to zero, install the ROOM fuse with the ignition switch at ON position.
- If the needle does not return to zero, remove the front lens and carefully move the needle to zero by hand.
