Headlight Leveling Motor Input Test
- Turn the ignition switch to LOCK (0).
- Disconnect the 3P connector (A) from the headlight leveling motor (B).
- 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.
- Reconnect the connector to the headlight leveling motor, and do the following input tests.
- If any tests indicate a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the headlight leveling motor (see HEADLIGHT LEVELING MOTOR REPLACEMENT ).
TEST CONDITION AND WIRE REFERENCE CHART
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 1 | YEL | Ignition switch ON (II) | Measure the voltage to ground: There should be battery voltage. |
|
| 2 | PNK | Ignition switch ON (II), headlight switch ON | Measure the voltage to ground: There should be at least 2-12 V.
NOTE:
Depending on the headlight leveling position.
|
|
| 3 | RED | Ignition switch ON (II) | Measure the voltage to ground: There should be less than 0.2 V. |
