Stratus V6-2.5L VIN H (1997)
Active Codes: A malfunction that is present now.
ACM: Airbag Control Module (also called the Air Bag System Diagnostic Module (ASDM)).
ASDM: Air Bag System Diagnostic Module (also called the Airbag Control Module (ACM)).
Air Bag Module: Also called "Squib" initiator - located inside the air bag module assembly.
Impact Sensor: G force sensitive, threshold switches which close when an impact of sufficient force in the correct direction occurs.
An impact switch closure accompanied by closure of the safing sensor, alerts the control module that it is now time to deploy the airbag(s).
Initiator: Also called "Squib" - located inside the air bag module assembly.
PASDM: Passenger Air Bag System Diagnostic Module
Safing Sensor: A switch inside the ASDM which must be closed at the same time at least one of the impact sensors is closed, to initiate
deployment of the airbag(s).
Squib: Also called "Air Bag Module" initiator - located inside the air bag module assembly.
SRS: Supplemental Restraint System
Stored Codes: A malfunction that had been present during a previous key cycle, may or may not be active.
Body Control Module
BODY CONTROL MODULE
The Body Control Module (BCM) supplies vehicle occupants with visual and audible information and controls various vehicle functions. To provide
and receive information, the module is interfaced to the vehicle's serial bus communications network (the Chrysler Collision Detection bus, or CCD
bus). This network consists of the Powertrain Control Module (PCM), the Transmission Control Module (TCM), the Electro/Mechanical Instrument
Cluster (MIC), the compass/mini-trip module and the Airbag Control Module (ACM). The BCM is operational when battery power is supplied to the
module. Ignition switch power is needed for ignition switched functions.
The body control module provides the following features:
-
A/C switch status/evaporator temperature status
-
Automatic door locks
-
Chimes
-
Courtesy lamps
-
BCM diagnostic support
-
Door lock inhibit
-
Headlamp time delay
-
Ignition key lamp
-
Illuminated entry with "fade to off" (JA models)
-
Instrument panel dimming
-
Manual A/C (mode door control)
-
Mechanical instrument cluster support
-
Power door locks (with/without remote keyless entry)
-
Vehicle Theft Security System (VTSS)
-
Windshield wiper/washer
Circuit Operation
CIRCUIT OPERATION
The Body Control Module (BCM) is used to supply the vehicles occupants with visual and audible information, control various vehicle functions,
and provide a centralized power distribution for the passenger compartment. To both provide and receive vehicle information the BCM is
interfaced to the CCD Bus.
Power for the BCM is supplied from four sources. One is the M1 circuit. This circuit is HOT at all times, and is the Ignition-Off Draw (IOD)
circuit. This circuit is protected by a 10 amp fuse located in cavity 5 of the junction block.
Power is also supplied to the BCM on circuit A21. This circuit is HOT when the ignition switch is in the START/RUN position only, and connects
from the ignition switch to the BCM. Power for the A21 circuit is supplied by circuit A1. Circuit A1 is connected between the PDC and the
ignition switch and is protected by a 20 amp fuse located in cavity 8 of the PDC.
Circuit F11, which is HOT when the ignition switch is in the OFF/RUN/START position, supplies a constant feed to the BCM. This circuit is
