Introduction
This document provides information on troubleshooting and resolving issues with rear door locking mechanisms. The document is compiled from real user experiences and technical knowledge.
Problem
The rear door (tailgate) intermittently fails to lock. Symptoms can include:
- Failure to lock with the remote or central locking system.
- No flashing lights or beeping sounds when attempting to lock.
- Issue may be intermittent.
- May occur regardless of cargo blind presence.
Solutions
-
Cargo Blind Modification: A known issue involves the rear cargo blind interfering with the locking mechanism. Toyota’s fix involves modifying (chamfering) the lugs on the cargo blind or replacing the entire blind. The rear-most flap on the blind (the bit between the lugs and the rear door) should be able to be tilted down about 45 degrees.
-
Rear Door Handle Assembly Replacement: Weak solenoid strength may prevent the door from locking. Replacing the rear door inside handle assembly will resolve this issue.
-
Check for Obstructions: Ensure no items are pressing against the door from the inside, which might prevent the locking mechanism from engaging correctly.
-
Manual Override Check: Manually ensure the inside lock part of the rear door is fully unlocked. This can sometimes temporarily resolve the issue, indicating a potential weakness in the solenoid.
Relevant Parts
-
Rear Cargo Blind: Field fix involves modifying or replacing the blind with one that has a cutout at the lock location or chamfered lugs.
-
Rear Door Inside Handle Assembly: Replacement of the handle assembly, which includes the solenoid, may be necessary.
