With Door Module
The driver side front door power switch assembly combines the following switches into a single unit:
- Power lock.
- Power window (for each of the four door windows including auto-down and express up for both front door windows).
- Power window lockout.
- Power mirror selector.
- Power mirror adjustment in a single unit.
The passenger side power door switch module combines a power lock switch and a passenger side front door power window switch with the auto-down and express up features.
The driver side front door power switch module provides resistor multiplexed outputs to the driver door module indicating the power lock switch selection. The power window switch selections are hard wired analog outputs indicating the power mirror selector switch, adjustment switch selections, and electronic message outputs over a Local Interface Network (LIN) data bus connection.
The passenger side front door power switch module provides resistor multiplexed outputs to the passenger door module indicating both the power lock and power window switch selections.
The hard-wired circuits between the driver side front door power switch module and the driver side door module or the rear door power window switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic controls and communication between the switch module and the door module or in the diagnosis of the electronic controls and communication between other modules and the door module that provide some features of the power lock, power mirror or power window systems. The most reliable, efficient, and accurate means to diagnose the driver side power switch module or the electronic controls and communication related to power lock, power mirror or power window system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
