Page 11: Introduction
INTRODUCTION The procedures contained in this manual include all the specifications, instructions, and graphics needed to diagnose 1999 300M body system problems. The diagnostics in this manual are based on the failure condition or symptom being present at the time of diagnosis. When repairs are required, refer to the appropriate service manual for the proper removal and repair procedure.
Page 12: System Description And Functional Operation
SYSTEM DESCRIPTION AND FUNCTIONAL OPERATION The body system on the 1999 300M consists of a combination of modules that communicate over the PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s).
Page 13 Perform the WARNING LAMP BULB OR DRIVER procedure in this book to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate • • warning lamp stays illuminated with no active DTC’s The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
Page 14: Airbag Diagnostic Trouble Codes
TRICITY. DO NOT STORE AT TEMPERATURE EXCEEDING 93°C (200°F). REPLACE AIRBAG SYSTEM COMPONENTS ONLY WITH PARTS SPECIFIED IN THE CHRYSLER MOPAR PARTS CATALOG. SUBSTITUTE PARTS MAY APPEAR INTER- CHANGEABLE, BUT INTERNAL DIFFERENCES MAY RESULT IN INFERIOR OCCUPANT PROTECTION. THE FASTENERS, SCREWS, AND BOLTS ORIGINALLY USED FOR THE AIRBAG SYSTEM COMPONENTS HAVE SPECIAL COATINGS AND ARE SPECIFICALLY DESIGNED FOR THE AIRBAG SYSTEM.
Page 15: Audio System
The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists.

Page 18: Climate Control Systems
Climate Control Systems 3.6.1 Automatic Temperature Control (ATC) The body control module (BCM) provides automatic temperature control support both through PCI bus communications and through processing inputs to determine control for actuators and the blower motor. The BCM interfaces with the ATC control head over the PCI bus. Information on button activation, blower setting, and temperature setting are supplied to the BCM.
Page 19: Rear Window Defogger
3.6.4 Rear Window Defogger When the BCM receives a rear defogger request from the climate control head (either ATC or manual) the BCM will activate the rear window defogger relay for 15 minutes. If the BCM receives another rear defogger request while the relay is still activated, the relay will be de-activated. If the relay is allowed to time out (full 15 minutes), further requests during the same ignition on period will cause the BCM to activate the relay for 7.5 minutes.
Page 20: Memory System
the button when the display is in the trip mode will reset the trip mileage. The cluster also supplies the power for the panel illumination. Most of the information that is displayed is received over the PCI bus from several modules. With ignition in lock , the cluster will wake up and display the door ajar and odometer display when a door is opened.
Page 21: Memory Seat Glide
3.10.2 Memory Seat Glide The intent of this feature is to allow for easier entry and exit to the vehicle by moving the seat rearward a short distance when the operator turns the ignition off. The seat returns to its original position when the operator returns and turns on the ignition or extends the seat belt.
Page 22: Power Door Lock System
Compass/Temperature AVE ECO Average Fuel Economy ECO Instantaneous Fuel Economy DTE Distance to Empty ET Elapsed Time ODO Trip Odometer If the vehicle is equipped with the optional Homelink feature, the OTIS will have three buttons located in the center of the OTIS module. The OTIS module receives all of its information over the PCI bus except compass, which is internal to the OTIS module.
Page 23: Sentry Key Immobilizer System (Skis)
3.14 Vehicle Communication The Chrysler Programmable Communication Interface multiplex system (PCI bus) consists of a single wire. The Body Control Module (BCM) acts as a splice to connect each module and the Data Link Connector (DLC) together. Each module is wired in parallel to the data bus through its PCI chip set and uses its local ground as the bus reference.
Page 24: Bus Failure Message
to sink this current and pull the bus to ground on the falling edge of the symbols. The bus resistance is minimum of 315 ohms to a maximum of 2 K ohms. The termination capacitance is required for noise filtering and to help in the symbol wave shaping. The bus capacitance shall not be greater then 12,000 pf.
Page 25: Wiper System
Arming/Disarming - Active arming occurs when the remote keyless entry transmitter is used to lock the vehicle doors, whether the doors are open or closed. If one or more doors are open, the arming sequence is completed only after all doors are closed. Passive disarming occurs upon normal vehicle entry (unlocking either front door with the key).
