Control Module
There are two versions of the driver information module (DIM):
- Standard Line, analog presentation. Contains a 2.3" monochrome TFT display.
- High Line, graphic presentation. Contains an 8" color TFT display.
The most important role of the driver information module (DIM) is to display the status of the vehicle systems for the driver. This covers functions such as:
- the vehicle speed
- engine speed
- fuel level
- engine coolant temperature (ECT)
- Eco guide (highline)
- Power gauge (highline)
- parking heater
- trip odometer
- Trip computer
- various warning signals.
The control module is integrated in the combined instrument panel. If the control module is replaced, the combined instrument panel must also be replaced.
The driver information module (DIM)communicates with other control modules and components via CAN communication.
The control module checks input and output signals, indicator lamps for ABS, the supplemental restraint system module (SRS) (airbag), and the yellow and red warning triangles through integrated diagnostics.
Any diagnostic trouble codes are stored in the control module memory. The data can be read off using the diagnostic tool.
An easy way of checking that the driver information module (DIM) is both powered and grounded is to check whether the following warning lamps come on when the ignition is switched on:
- parking brake
- Malfunction indicator lamp (MIL).
- brake fluid level.
