Automatic Lighting/Rain Sensor Input Test
NOTE:
- 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 No. A18 (10 A) fuse in the under-hood fuse/relay box is OK.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the automatic lighting/rain sensor 5P connector .
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.
4. Reconnect the connector, and do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the automatic lighting/rain sensor .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 1 | YEL | Combination light switch OFF | 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. |
|
| 5 | RED | Under all conditions | Measure the voltage to ground: There should be battery voltage. |
