Circuit/System Description

This vehicles power mode master (PMM) is the body control module (BCM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination of the power mode. The PMM receives the ignition switch signals, and additionally a reference voltage signal from the BCM, through the ignition switch, and back to the BCM. There are redundancies within the PMM system that can allow operation of certain subsystems when there are faults in the ignition switch circuits. Other information such as serial data input from other modules and DTCs is also used to determine what power mode signals and information is transmitted by the PMM. The BCM logic uses all this information to identify the operators desired power mode and activate specific discrete signals, and serial data messages for the operation of many different subsystems as necessary. Other modules which have switched voltage inputs may operate in a default mode if the PMM serial data message does not match what the individual module can see from its own connections.

The PMM will activate relays and other direct outputs of the PMM as needed according to the calculated power mode. Several relays controlled by the BCM are switched ignition voltage outputs the are pass through circuits within the BCM directly from the ignition switch. If these circuits short to ground, the fuse to the ignition switch will open. Some system functions may operate one time and not the next with a specific fault in the ignition switch circuits depending on the vehicle operating conditions when the fault occurred. Some examples are as follows

Vehicle Conditions

1. Vehicle running or not running
2. Multiple circuit faults
3. Ignition key position
4. Transmission gear selected

System Action

1. The vehicle may or may not start
2. Instrument panel indicators may illuminate or not illuminate at inappropriate times
3. Remote start may operate incorrectly
4. Ignition key may not return to OFF
5. Specific Retained Accessory Power (RAP) functions may operate while others do not

The body control module (BCM) controls the IGN MAIN relay 31 by applying voltage to the circuit. The IGN MAIN relay 31 is energized when the ignition switch is in RUN or START, or when a remote start is requested.

The body control module (BCM) controls the R3 RUN relay through the run relay coil control circuit by applying voltage to the coil side of the relay. The R3 RUN relay is energized when any of the following conditions are true

1. Ignition Switch is in ACC or RUN.
2. The vehicle was remote started.
3. The vehicle is in retained accessory power (RAP) mode.

The body control module (BCM) controls the RAP relay through the rap relay coil supply voltage circuit by applying voltage to the coil side of the relay. The RAP relay is energized when any of the following conditions are true

1. Ignition switch is in ACC or ON.
2. The vehicle was remote started.
3. The vehicle is in RAP mode.
