Carrying the Intelligent Key, enables the driver to open the liftgate using the back door handle even when the
vehicle is locked. When lifting the handle, the back door
handle switch sends this signal to the Intelligent Key
unit which treats it as a request switch signal. When t he Intelligent Key unit, using the rear bumper antenna,
validates the presence of the Intelligent Key, it s ends an open signal to the back door control unit regardless
whether the vehicle is locked.
Rear bumper antenna is mounted on the rear bumper and is used to allow the back door handle opening of
the locked back door when the Intelligent Key is present.
Diagnosis ProcedureINFOID:0000000003775814
1.BACK DOOR HANDLE SWITCH SIGNAL INSPECTION
With all doors unlocked, check the back door handle operation by lifting the handle.
Did the back door respond correctly by opening?
YES >> GO TO 2
NO >> Refer to DLK-138, "
Diagnosis Procedure".
2.KEYFOB SIGNAL INSPECTION
Check keyfob operation using lock and unlock buttons.
Did the keyfob respond correctly?
YES >> GO TO 3
NO >> Refer to DLK-106, "
Diagnosis Procedure".
3.INTELLIGENT KEY UNIT SIGNAL INSPECTION
NOTE:
Since the diode is a uni-directional component, pay close attention to the polarity of the ohmmeter
being used as the presence of a diode in the circuit will affect the result.
1. Turn ignition switch OFF.
2. Disconnect Intelligent Key unit, back door handle switch and back door control unit connectors.
3. Check continuity between Intelligent Key unit connector (A) M70 terminal 29 and back door handle switch connector (B) D706
terminal 3.
4. Check continuity between Intelligent Key unit connector (A) M70 terminal 29 and ground.
Is the inspection result normal?
YES >> Replace the Intelligent Key unit.
NO >> Repair or replace the harness or the diode as necessary. 29 (+) - 3 (-) : Continuity should exist.
29 (+) - Ground (-) : Conti
nuity should not exist.
