COMMENT ON TROUBLE SYMPTOM
If the doors are not unlocked when the selector lever 
is shifted to the "P" position, the shift position signal 
input circuit(s) or the ETACS-ECU may be defective. 
Also, the function to interlock the shift P position with 
door unlocking may have been disabled with a cus-
tomise function.

POSSIBLE CAUSES

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. Checking central door unlocking 
operation
Check that the central door locking system works 
normally.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO :
