AUTOMATIC BACK DOOR SYSTEM
signal to the BCM through terminal 4 to flash the hazard lamps and unlocks the back door latch through ter-
minal 12.
• The back door control unit supplies power to the magnetic clutch and the back door motor and moves the
back door in the open direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door is opened to the full-open position, the full-open position is detected by the encoder,
and the back door control unit switches the back door motor OFF and the magnetic clutch is pulsed and then
turned OFF.
• The back door is held in the fully open position by the gas stays.
Power Liftgate Switch Operation (Fully Open → Fully Closed Operation)
• When the power liftgate switch is pressed, the back door control unit terminal 23 receives the signal.
• The back door control units checks door position through the rotary encoder.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
met, it sends a signal through terminal 6 and grounds terminal 9 to sound the warning chime and sends a
signal to the BCM through terminal 4 to flash the hazard lamps.
• The back door control unit supplies power to the magnetic clutch and the back door motor and move the
back door in the close direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door reaches the half-latch state, the half-latch switch detects this and the signal is sent to
the back door control unit terminal 22.
• When the back door control unit receives the half latch switch signal, it switches OFF the back door motor
and the magnetic clutch and operates the cinch latch motor.
• When the back door latch operates and full close is detected through terminal 14 of the back door control
unit, the cinch latch motor reverses to the neutral position and the back door auto closure operation ends
and the door is fully closed.
Remote Keyless Entry Operation (Fully Open → Fully Closed Operation)
• When the keyfob switch is pressed for at least 0.5 seconds, the back door control unit terminal 21 receives
the signal.
• The back door control units checks door position through the rotary encoder.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
met, it sends a signal through terminal 6 and grounds terminal 9 to sound the warning chime and sends a
signal to the BCM through terminal 4 to flash the hazard lamps.
• The back door control unit supplies power to the magnetic clutch and the back door motor and move the
back door in the close direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door reaches the half-latch state, the half-latch switch detects this and the signal is sent to
the back door control unit terminal 22.
• When the back door control unit receives the half latch switch signal, it switches OFF the back door motor
and the magnetic clutch and operates the cinch latch motor.
• When the back door latch operates and full close is detected through terminal 14 of the back door control
unit, the cinch latch motor reverses to the neutral position and the back door auto closure operation ends
and the door is fully closed.
Back Door Close Switch Operation (Fully Open → Fully Closed Operation)
• When the back door close switch is pressed, the back door control unit terminal 8 receives the signal.
• The back door control units checks back door close switch terminal 13 status and door position (must be
fully opened), through rotary encoder and battery voltage.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
met, it sends a signal through terminal 6 and grounds terminal 9 to sound the warning chime and sends a
signal to the BCM through terminal 4 to flash the hazard lamps.
• The back door control unit supplies power to the magnetic clutch and the back door motor and move the
back door in the close direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door reaches the half-latch state, the half-latch switch detects this and the signal is sent to
the back door control unit terminal 22.
• When the back door control unit receives the half latch switch signal, it switches OFF the back door motor
and the magnetic clutch and operates the cinch latch motor.
• When the back door latch operates and full close is detected through terminal 14 of the back door control
unit, the cinch latch motor reverses to the neutral position and the back door auto closure operation ends
and the door is fully closed.

P Reversal
The door will reverse direction during power open or close operation if the automatic door main switch, keyfob
or back door close switch is operated. A chime will sound to announce the reversal.
Anti-Pinch Function
• During auto operation, if an object is detected in the door's path, a warning chime sounds and the back door
operates in the reverse direction to prevent pinching.
• During auto close operation, if an object is detected by the pinch strips in the door's path, a warning chime
sounds and the back door operates in the open direction until it is fully open.
Gas Stay Check
• During each power open operation, the back door control unit monitors motor current draw to determine if
the gas stays are functioning properly.
• If a malfunction of the gas stays is detected, the back door control unit will close the back door while sound-
ing the warning chime. The back door cannot be opened using the switches until the gas stay malfunction is
repaired.
Warning Functions
• The hazard warning lamps flash and a warning chime is sounded according to the back door operating state,
operations, and conditions.

Self-Diagnosis ProcedureINFOID:0000000003532964
INPUT SIGNAL CHECK MODE
Input signal check mode allows testing of switch input signal to the back door control unit.
To activate input signal check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
8. Release the back door handle switch.
9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
11. Release the power liftgate switch.
12. The input signal check mode is now initialized.
The input signal check mode can test the following inputs. The back door warning chime will sound for approx-
imately 0.5 seconds each time a switch signal input occurs. Use this test when one of these inputs is not
responding during normal automatic back door operation.
*Back door warning chime should sound as soon as vehicle moves.
Turn ignition switch OFF to end input signal check mode.
OPERATING CHECK MODE
Operating check mode allows self-diagnosis of the automatic back door system.
To activate operating check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
