Dash Integration Module (DIM)

Battery voltage is provided from the rear fuse block to the DIM. The module ground is wired to ground. Battery positive sense voltage is provided from the rear fuse block to the DIM. This battery input is referenced to the ground sense input at DIM which is wired to the battery negative terminal and to ground. These sense inputs are physically connected to the battery positive and negative terminals for accurate battery voltage readings. The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.

The DIM functions include the following functions:
^ Battery voltage sense and load management
^ Control of headlights and exterior lamps
^ Cooling fan control (power - train cooling)
^ Horn relay control for theft activation
^ Incandescent dimming of dash bulbs control
^ Interior lamps incandescent dimming
^ Lamps On signal with wiper/washer
^ Low side temperature for HVAC compressor
^ Power moding control (ignition switch states) over Class 2 serial data line
^ Real time clock time keeper
^ Reverse lockout solenoid control
^ Steering wheel controls
