The electronic brake control module (EBCM) sets DTCs related to the ABS system and sends a class 2 serial data message requesting illumination of the ABS indicator. If the IPC detects a loss of communication with the EBCM, the IPC uses the status of the back-up discrete ABS indicator signal to determine whether the IPC should illuminate the ABS indicator. The IPC sends a class 2 serial data message requesting the radio to activate a single pulse chime. The IPC also illuminates the TRACTION CONTROL indicator and displays the SERVICE STABILITY SYS message on the DIC.

The IPC receives a discrete input from the brake fluid level switch. When the IPC receives a low signal from the brake fluid level switch, the IPC sends a class 2 serial data message requesting a single chime to sound. The IPC also illuminates the BRAKE indicator and displays the CHECK BRAKE FLUID message.

The IPC receives the status of the doors from each door module via class 2 serial data message. The IPC sends a class 2 serial data message requesting the radio to activate a medium rate 5 pulse chime when all of the following conditions occur:

The IPC also displays the appropriate message on the DIC:

The IPC receives engine coolant temperature information from the powertrain control module (PCM) via class 2 serial data messages. When the engine coolant temperature is greater than 128°C (262°F), the IPC sends a class 2 serial data message requesting the radio to activate a medium rate 5 pulse chime. The IPC also illuminates the engine coolant temperature indicator and displays the ENGINE COOLANT HOT/IDLE ENGINE message on the DIC.

The PCM determines if the oil pressure is low and sends a class 2 serial data message requesting illumination of the engine oil pressure indicator. The IPC sends a class 2 serial data message requesting the radio to activate a medium rate 5 pulse chime and also displays the OIL PRESSURE LOW/STOP ENGINE message on the DIC.

The PCM determines if the engine is overheated and sends a class 2 serial data message requesting the radio to activate a medium rate 5 pulse chime. The IPC also displays the ENGINE OVERHEATED/STOP ENGINE message on the DIC.

The inflatable restraint sensing and diagnostic module (SDM) receives a discrete seat belt switch input. The SDM sends class 2 serial data messages to the instrument cluster (IPC) indicating the seat belt switch status. If the driver's seat belt is unfastened within 8 seconds following the bulb check, the IPC illuminates the fasten safety belt indicator for up to 72 seconds. At the same time, the IPC sends a class 2 serial data message requesting the radio to activate a slow rate 5 pulse chime. If the driver's seat belt is buckled during the 5 pulse chime period, the chime stops and the indicator turns off.

The IPC receives the filtered fuel level status from the rear integration module (RIM) via class 2 serial data messages. When the fuel level is less than 11.4 liters (3 gallons), the IPC sends a class 2 serial data message requesting the radio to activate a single pulse chime. The IPC also displays the FUEL LEVEL LOW message on the DIC.

The instrument panel integration module (IPM) receives a discrete key-in-ignition signal input. The driver door module (DDM) receives a discrete LH front door jamb switch signal input. The rear integration module (RIM) receives the key-in-ignition status from the IPM and LH front door status from the DDM via a class 2 serial data messages. The RIM sends a class 2 serial data message requesting the radio to activate a medium rate multiple chime when all of the following conditions occur:

The dash integration module (DIM) receives a discrete headlamp switch or park lamp switch signal input. The driver door module (DDM) receives a discrete LH front door jamb switch signal input. The DIM receives the LH front door status from the DDM via a class 2 serial data messages. The DIM sends a class 2 serial data message requesting the radio to activate a fast rate multiple chime when all of the following conditions occur:

The IPC also continues to illuminate the LIGHTS ON indicator.

The PCM determines if the transmission is too hot and sends a class 2 serial data message requesting the radio to activate a medium rate 5 pulse chime. The IPC also displays the TRANS HOT IDLE ENGINE message on the DIC.

The IPC receives a discrete turn signal input for each turn indicator. If a turn signal remains on and the vehicle has travelled more than 1.6 kilometers (1 mile), the IPC sends a class 2 serial data message requesting the radio to activate a chime. The IPC also displays the TURN SIGNAL ON message on the DIC. The chime sounds once per flash of the turn signal as long as the turn signal remains active.

The electronic brake control module (EBCM) sets DTCs related to the VSES system and sends a class 2 serial data message requesting the radio to activate a single pulse chime. The IPC also displays the SERVICE STABILITY SYS message on the DIC.
