Intrigue V6-3.8L VIN K (1998)
^
Serial Data: provides an interface with the PCM, EBTCM, and the PC through the Class II serial data link.
BCM Outputs
The BCM directly controls these outputs, plus other systems may request the BCM to control these outputs for certain functions:
^
All Door Lock: When active, supplies voltage to the door lock actuators and locks the doors; when inactive, provides ground to the door lock
actuators.
^
Courtesy Lights B+ Output: Supplies voltage to the courtesy lights, providing an inadvertent load (battery rundown) protection.
^
Driver Door Unlock: Supplies ground to the door lock relay, which provides power to the driver door actuator, and unlocks the driver's door lock.
^
DRL Link: Provides an interface to the DRL control module allowing the BCM to determine the current ambient light operating mode, and to
activate the vehicle headlamps for alarm.
^
Fog Lamp Enable Control: Sends a ground signal to the fog lamp switch when the ignition switch on; this action enables the fog lamp switch. The
fog lamps turn on when the fog lamp switch is enabled by the BCM.
^
Horn: Sends a ground signal to the horn relay, sounding the horn for the keyless entry alarm function.
^
Passlock Sensor Power: Provides B+ for Passlock sensor operation.
^
Passlock Sensor Ground: Provides ground to the Passlock sensor.
^
Passenger Door Unlock: When active, supplies voltage to the door lock actuators and unlocks the doors (except the driver's door); when inactive,
provides ground to the door lock actuators.
^
RFA Link: Provides an interface allowing the transfer of keyless entry information to the Remote Control Door Lock Receiver (RCDLR).
^
Serial Data: provides an interface with the PCM, EBTCM, and the instrument cluster through the Class II serial data link.
^
Theater Dimming 1: Supplies ground to activate the I/P and door courtesy lamps.
^
Theater Dimming 2: Supplies ground to activate the dome and the roof rail courtesy/reading lamps.
BCM Wake-Up/Sleep State
The BCM performs its functions in the wake-up state. The BCM enters the sleep state when active control or monitoring of system malfunctions has
stopped, or when the BCM is idling. The BCM must detect certain wake-up inputs before entering the wake-up state. The BCM monitors its inputs
during the sleep state, allowing the BCM to switch between the two states, awake or asleep.
The BCM enters the wake-up state when receiving activity on any of these inputs:
^
I/P dimmer switch.
^
Door lock (ajar) switch.
^
Door lock switch.
^
A keyless entry system signal.
^
Inadvertent power (battery rundown) protection transition.
^
The ignition is turned to off, accessory or on. The sleep state is when the BCM has stopped active control and monitoring of system functions and
has become idle again. For the BCM to enter the wake-up state, the BCM must detect a wake-up condition, mentioned previously. These
conditions are called wake-up inputs that cause the BCM to change from a sleep to a wake-up state and begin active control and monitoring. The
BCM has the ability to monitor for these wake-up inputs in the sleep state. The BCM enters the sleep state when all of these conditions exist:
^
No activity on the Class II serial data link.
^
The ignition switch is off.
^
The BCM is not commanding any outputs.
^
No delay timers are actively counting (during theft deterrent re-learn).
^
No wake-up inputs are present.
Power Requirements
The BCM has three main voltage feeds and one ground. Circuit 2340 is used to provide power for the BCM's logic and internal driver operation.
Circuit 1540 provides power for the automatic door lock. Circuit 240 provides power to the courtesy lights.
Interior Lighting Control
^
Interior illumination control.
^
Delayed illumination.
^
Illuminated entry.
^
Exit illumination.
^
Theater dimming.
^
Keyless entry unlock illumination.
^
Inadvertent load (battery rundown) protection.
Keyless Entry
^
Remote driver door unlock.
^
Remote all door unlock.
^
Remote all door lock.
^
Remote activation verification.
^
Remote alarm.
^
Feature customization of remote activation verification.
Miscellaneous Functions
^
BRAKE indicator lamp control: The BCM controls the state of the BRAKE indicator lamp based on the status of the parking brake switch by
sending a message to the instrument cluster via the Class II serial data link.
^
Fog lamp enable control, The BCM controls fog lamp operation, based on the status of the ignition switch.
