This PI was superseded to update model and model years. Please discard PIT4893A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment that the door lock actuators are inoperative intermittently. This may be caused by an
excessive use of the key fob button or door lock/unlock switch. If the lock or unlock button/switch is pressed several
times, repeatedly within 45 seconds, the door lock actuators will temporarily become inoperative.
Recommendation/Instructions:
To correct the temporarily inoperative state, it will be necessary to wait up to 15 seconds (depending on the number
of times the button/switch was pressed), without depressing the lock/unlock button/switch. This will allow the system
to regain functionality. This is design intent to prevent premature wear to the door lock actuators. This is a normal
operating characteristic and no repairs are recommended for this concern.
ADDITIONAL SI KEYWORDS:
RKE
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.
