LIFTGATE AUTO CLOSURE SYSTEM OPERATION
id091100537300
Timing chart
1. Retracting
-
• If the liftgate latch auto closure control module detects that the half-latch switch of the liftgate latch position switch is off, TR1 and TR3 turns on and TR2 turns off (1). As a result, relay A and C are switched (2) and the motor rotates normally.
2. Initial position change
-
• When the liftgate latch auto closure control module detects that the full-latch switch of the liftgate latch position switch is off (over-stroke), the liftgate latch closure motor stops and TR2 and TR3 turns on and TR1 turns off after approx. 0.1 s (1). As a result, relay B and C are switched (2) and the motor switches from normal to reverse operation.
