NOTE:
- Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
- If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .
- Before testing, make sure the fuses associated with the system is OK.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the automatic lighting/rain sensor 5P connector.
AUTOMATIC LIGHTING/RAIN SENSOR 5P CONNECTOR (female terminals)
3. Inspect the connector and socket terminals to be sure they are all making good contact:
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals are OK, go to step 4.

| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 5 | WHT | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
An open or high resistance in the wire |
| 2 | BLK | In all power modes | Measure the voltage to ground: There should be less than 0.2 V. |
|
| 1 | BRN | Combination light switch in any position, other than headlight ON. | Measure the voltage to ground: There should be about 5 V. |
An open or high resistance in the wire |
