Instrument Panel Module (IPM)
WARNING: This page is about a different car, the 2008 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The following are the ACC System functions provided by the IPM:
- The IPM provides a translating gateway for the high speed GMLAN serial data circuit.
- The IPM reads all cruise control switches and the gap switch. The DSCC module monitors a variety of user operated switches from the IPM switch status information sent via the GMLAN serial data circuit.
- The IPM illuminates the brake light based on a GMLAN message from the DSCC module during automatic braking.
- The IPM measures the brake pedal position and sends brake pedal travel status via GMLAN serial data circuit to the ECM. The ECM disengages the ACC System when the brake is applied by the driver pressing the brake pedal.
- The IPM serves as a gateway to the display systems, instrument panel cluster (IPC), DIC and amplifier, visual and audible warnings. The IPM will generate visual and audible warnings based on high speed GMLAN serial data messages from the DSCC module.
