Super Locking Control Unit Input Test

1.Remove the each door panel.

2.Disconnect the 8 P connector (A) from the super locking control unit (B).

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 look OK, make the following input tests at the connector.
    • If a test indicates a problem, find and correct the cause, then recheck the system.
    • If all the input tests prove OK, the control unit must be faulty, replace it.

 

Cavity Wire Test condition Test: Desired result Possible cause if result is not obtained 
BLK Under all conditions Check for continuity to ground:
There should be continuity.
