1.CHECK SUNLOAD SENSOR POWER SUPPLY CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect the sunload sensor connector.
3. Turn the ignition switch ON.
4. Check voltage between sunload sensor harness connector and ground.

   (+) | (−) | Voltage (Approx.)
   Sunload sensor | —
   Connector | Terminal
   M96 | 1 | Ground | 5 V

Is the inspection result normal?
YES>>GO TO 2.
NO>>GO TO 4.
2.CHECK SUNLOAD SENSOR CIRCUIT CONTINUITY

1. Turn the ignition switch OFF.
2. Disconnect the A/C auto amp. connector.
3. Check for continuity between the sunload sensor harness connector and the A/C auto amp. harness connector.

   Sunload sensor | A/C auto amp. | Continuity
   Connector | Terminal | Connector | Terminal
   M96 | 2 | M66 | 37 | Existed

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair the harnesses or connectors.
3.CHECK SUNLOAD SENSOR

1. Connect the sunload sensor connector.
2. Connect the A/C auto amp. connector.
3. Check the sunload sensor components. Refer to Component Inspection.

Is the inspection result normal?
YES>>Replace the A/C auto amp.
NO>>Replace the sunload sensor.
4.CHECK SUNLOAD SENSOR CIRCUIT CONTINUITY

1. Turn the ignition switch OFF.
2. Disconnect the A/C auto amp. connector.
3. Check for continuity between the sunload sensor harness connector and A/C auto amp. harness connector.

   Sunload sensor | A/C auto amp. | Continuity
   Connector | Terminal | Connector | Terminal
   M96 | 1 | M66 | 15 | Existed

4. Check for continuity between sunload sensor harness connector and ground.

   Sunload sensor | — | Continuity
   Connector | Terminal
   M96 | 1 | Ground | Not existed

Is the inspection result normal?
YES>>Replace A/C auto amp.
NO>>Repair the harnesses or connectors.
