Pinpoint Test T: The Liftgate/Luggage Compartment Lid Passive Entry Feature Is Inoperative
- T1 CHECK THE LIFTGATE/LUGGAGE COMPARTMENT LID RELEASE OPERATION FROM THE RELEASE SWITCH
- Electronically unlock the doors.
- Press the liftgate/luggage compartment lid release button.
Does the liftgate/luggage compartment lid latch release?
- Yes : GO to T2
- No : GO to PINPOINT TEST L
- T2 CHECK THE RKE (REMOTE KEYLESS ENTRY) OPERATION
- Close the liftgate/luggage compartment lid.
- Press the liftgate button twice on a passive key.
Does the liftgate/luggage compartment lid latch release?
- Yes : GO to T3
- No : GO to PINPOINT TEST N
- T3 CHECK FOR COMMUNICATION WITH THE BCM (BODY CONTROL MODULE) AND RFA (REMOTE FUNCTION ACTUATOR) MODULE
- Ignition ON.
- Using a diagnostic scan tool, perform a network test.
Does the BCM and the RFA module pass the network test?
- Yes : GO to T4
- No : REFER to: COMMUNICATIONS NETWORK .
- T4 CHECK THE RFA (REMOTE FUNCTION ACTUATOR) MODULE TRUNK/DECKLID LOCK SWITCH (TR_LK_BUT) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the RFA module Parameter Identifications (PIDs).
- Press the liftgate/luggage compartment lid release switch while monitoring the RFA module PID TR_LK_BUT.
Does the PID indicate the switch is being pressed?
- Yes : GO to T6
- No : GO to T5
- T5 CHECK THE RELEASE SWITCH INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect Liftgate/Luggage Compartment Lid Release Switch C4224 .
- Disconnect RFA C4392E .
- Measure:
Positive Lead Measurement/Action Negative Lead C4392E-18 C4224-2
Is the resistance less than 3 ohms?
- Yes : GO to T10
- No : REPAIR the circuit.
- T6 CHECK THE REMOTE KEYLESS ENTRY REAR ANTENNA
- Ignition OFF.
- Disconnect Keyless Entry Rear Antenna C4082 .
- Measure:
Positive Lead Measurement/Action Negative Lead
C4082, Pin 1, component side
C4082, Pin 2, component side
Is the resistance between 1 and 3 ohms?
- Yes : GO to T7
- No : INSTALL a new keyless entry rear antenna.
- T7 CHECK THE REMOTE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE
- Disconnect RFA Module C4392A .
- Ignition ON.
- Measure:
Positive Lead Measurement/Action Negative Lead C4082-1 Ground C4082-2 Ground
Is any voltage present?
- Yes : REPAIR the circuit in question.
- No : GO to T8
- T8 CHECK THE REMOTE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO GROUND
Are the resistances greater than 10, 000 ohms?
- Yes : GO to T9
- No : REPAIR the circuit in question.
- T9 CHECK THE LIFTGATE REMOTE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN
Are the resistances less than 3 ohms?
- Yes : GO to T10
- No : REPAIR the circuit in question.
- T10 CHECK FOR CORRECT RFA (REMOTE FUNCTION ACTUATOR) MODULE OPERATION
- Disconnect and inspect all the RFA module connectors.
- Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals pins
- pushed-out pins - install new pins as necessary
- Reconnect all the RFA module connectors and make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
- Yes
: CHECK OASIS
for any applicable Technical Service Bulletins (TSBs). If a TSB
exists for this concern, DISCONTINUE this test and FOLLOW TSB
instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RFA
module.
REFER to: REMOTE FUNCTION ACTUATOR (RFA) MODULE .
- No : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
