1. Measure the voltage at each terminal.

- If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under "Inspection item(s)".

- If there is any malfunction, inspect the parts under "Inspection item(s)".

- If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the panel light control switch.
