All Doors Cannot Be Locked / Unlocked Simultaneously
DOOR LOCK: POWER DOOR LOCK CONTROL SYSTEM: All Doors cannot be Locked / Unlocked Simultaneously
- All Doors cannot be Locked / Unlocked Simultaneously
DESCRIPTION
The driver side junction block assembly (multiplex network body ECU) receives switch signals from the door control switch on the power window regulator master switch assembly, door control switch assembly, front door LH key cylinder and front door RH key cylinder, and activates the door lock motor on each door accordingly.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK OPERATION (ALL DOORS LOCK/ UNLOCK)
(a) All doors can be locked/unlocked at once using the following:
* Door control switch on the power window regulator master switch assembly (switch operation)
* Door control switch assembly (switch operation)
* Door key cylinder linked with door lock on the front door LH (key operation)
* Door key cylinder linked with door lock on the front door RH (key operation)
(b) Proceed to the next step according to the symptom if all the doors cannot be locked / unlocked at once.
Result
B -- INSPECT DOOR CONTROL SWITCH ASSEMBLY
C -- INSPECT FRONT DOOR LOCK ASSEMBLY LH
D -- INSPECT FRONT DOOR LOCK ASSEMBLY RH
A -- Continue to next step.
