- Perform SIGNAL CHECK . While performing signal check, lightly tap on corners of control unit and display unit with screwdriver while watching meter display. If no change occurs, speedometer circuit is functioning properly.
- If results are not okay, replace control unit. If results are okay, check wire harness between speedometer and speed sensor. If harness is good, replace speed sensor.
