Automatic Lighting/Rain Sensor Input Test

NOTE: Before testing, make sure the B-CAN communication lines are OK using the HDS.

1. Remove the cover from the automatic lighting/rain sensor.

1. Disconnect the 6P connector (A) from the automatic lighting/rain sensor (B).

1. 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 look OK, go to Step 4 .

1. With the connector still disconnected, make these input tests at the connector.
   - If any test indicates a problem, find and correct the cause, then recheck the system.
   - If all the input tests prove OK, replace the sensor.

   Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained
   --- | --- | --- | --- | ---
   1 | GRN | Under all conditions(disconnect driver's under-dash fuse/relay box connector Q (20P)) | Check for continuity between the terminal and driver's under-dash fuse/relay box connector Q (20P) No. 8 terminal: There should be continuity. | An open in the wire

   2

   WHT

   Under all conditions

   Measure the voltage to ground: There should be battery voltage.

   - Blown No. 15 (10 A) fuse in the under-hood fuse/relay box
   - An open in the wire

   3

   BRN

   Ignition switch ON (II)

   Measure the voltage to ground: There should be battery voltage.

   - Blown No. 15 (10 A) fuse in the under-hood fuse/relay box
   - Faulty driver's under-dash fuse/relay box
   - An open in the wire

   4

   BLK

   Under all conditions

   Check for continuity to ground: There should be continuity.

   - Poor ground (G501)
   - An open in the wire
