PROCEDURE
1. INITIALIZATION
 

Perform the initialization of the power rear gate auto closer, when the ground terminal is connected to the battery sensor with the rear gate open. Initialization is not required when the ground terminal is connected to the battery sensor with the rear gate closed.

1.

Turn the ignition switch to OFF.

2.

Close the rear gate slowly, and release the hold of rear gate after a clicking sound is heard when the latch is engaged halfway.

3.

The auto closer function then operates and pulls the rear gate to engage fully.

4.

Operate the power rear gate switches after the rear gate is closed fully to check that automatic open/close of the power rear gate operates normally. If the power rear gate still does not operate properly, perform the following diagnostic procedures. POWER REAR GATE(DIAGNOSTICS)>Basic Diagnostic Procedure
