Door Module: Description and Operation
MODULE-DOOR
DESCRIPTION
The door modules control the express up and down feature as well as normal window functions. It is used only on vehicles equipped with the express up
feature. If equipped with memory system, the door module controls the memory mirror. The modules are attached to each front door trim panel.
OPERATION
If the vehicle is equipped with the Express Up power window feature there will be a door module on each front door trim panel. The power window
switches and motors are directly wired to the modules. If the vehicle is equipped with the Memory System, the exterior power mirrors and switches are
also directly wired to the modules along with the rear door window switches. The modules are wired to the accessory delay relay which allows the
operation of the windows and mirrors for a given period of time after the ignition is turned off and providing the doors are not opened. The modules
communicate with each other and other modules on the vehicle via the CAN-B bus circuit. There are several Diagnostic Trouble Codes (DTC's) the
modules will store if there are problems with the power window system or the memory power mirror system.
ANTI-PINCH
The "Anti-Pinch" function is a safety feature that senses obstacles at the top of the glass and anywhere on the seal where it meets the glass to close during
the window closing operation. When a front window switch is pressed to the "Auto-Up" position and the closing window traps an object and the sense
current passes its limit, the module will stop the motor and drive the window down approximately 200 millimeters. The pinch force is speed dependent
which means that if the vehicle is going over 2km per hour the pinch force will be higher than if the vehicle is stopped.
PANIC MODE
If the window switch is held in the "Auto-Up" position and the closing window traps an object, the module will stop the motor and when the switch is
released will drive the window in the opposite direction approximately 10 millimeters. If within 8 seconds after the switch was released to the neutral
position, the switch is held again to the "Auto-Up" position, the module will enter the second panic mode. During the second panic mode, the module
will drive the motor with full (stall) force and stop. If within 8 seconds after the switch is released again to the neutral position, the switch is held again to
the "Auto-Up" position, the module will drive the motor again with full (stall) force and stop.
