PANEL LIGHT CONTROL SWITCH INSPECTION

B3E091866600W02

1. Measure the voltage at each terminal (other than terminal D).

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

2. Disconnect the panel light control switch connector.

3. Verify that continuity at terminal D is as indicated in the Terminal Voltage Table (Reference).

  • 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.

## Terminal Voltage Table (Reference)

Terminal | Signal name | Connected to | Measured condition | Voltage (V)/Continuity | Inspection item(s)
--- | --- | --- | --- | --- | ---
B | TNS | PJB | Turn the light switch to the TNS or ON position. | B+ | • PJB (See PASSENGER JUNCTION BOX (PJB) INSPECTION.) • ILLUMI 7.5 A fuse • Related wiring harnesses
Turn the light switch to the OFF position. | 1.0 or less
D | GND | Body ground | Under any condition: Inspect for continuity to ground. | Continuity detected | • GND • Related wiring harnesses
F | Panel light control | Illumination bulb | Panel light control switch turn to the brightest setting. | GND | • PJB (See PASSENGER JUNCTION BOX (PJB) INSPECTION.) • Related wiring harnesses
Panel light control switch turn to the darkest setting. | (See PASSENGER JUNCTION BOX (PJB) INSPECTION.)
H | Panel light control input | Panel light control switch | Panel light control switch turn to the brightest setting. | Approx. 4.5 | • PJB (See PASSENGER JUNCTION BOX (PJB) INSPECTION.) • Related wiring harnesses
Panel light control switch turn to the darkest setting. | 1.0 or less

## Terminals H Inspection

1. Measure the wave pattern of panel light control switch terminals H using a tester.

2. Turn the light switch to the TNS or ON position.

3. Verify that the resistance changes smoothly while turning the panel light control switch from the brightest to the darkest setting.
