INSTALLATION (1) Place the BCM onto the mounting bracket. bulkhead (Fig. 2). (3) Connect the five wire connectors to the BCM. Body Control Module (BCM) mounting assembly. (5) Install the knee blocker airbag (Refer to 8 - ELECTRICAL/RESTRAINTS/KNEE BLOCKER AIR- (6) Install the lower instrument panel silencer. WARNING: DO NOT CONNECT THE BATTERY NEG- CABLE. (Refer to 8 - ELECTRICAL/RE- STRAINTS - DIAGNOSIS AND TESTING - AIRBAG FIRST. FAILURE TO DO SO COULD RESULT IN OCCUPANT PERSONAL INJURY OR (7) Verify vehicle and system operation. COMMUNICATION DESCRIPTION The Programmable Communication Interface (PCI) data bus is a single wire multiplexed network capa- nections. The modules are wired in parallel. Connec- The modules used include: • Integrated Power Module (IPM) • Next Generation Controller (NGC) • Instrument Cluster (IC) • Electronic Vehicle Information Center (EVIC) • Occupant Restraint Controller (ORC) • Compass/Mini-Trip (CMTC) • Overhead Console • Controller Antilock Brake (CAB) • Automatic Temperature Control Module (ATC) • Power Liftgate Module (PLGM) • Radio • CD Changer • Memory/Heated Seat Adjustable Pedal Module • Sentry Key RemotE Entry Module (SKREEM) • Driver Door Module (DDM) • Passenger Door Module (PDM) in order to transmit and receive messages. The bus OPERATION The PCI bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only t scan tool. The 12v square wave selection on the 20-volt scale provides a good view of The PCI Bus failure modes are broken down into two categories. Complete PCI Bus Communication Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: • All gauges on the cluster stay at zero • All telltales on cluster illuminate • cluster backlighting at full intensity • No response received from any module on the PCI Bus (except the NGC) • No start (if equipped with Sentry Key Immobi- lizer) Symptoms of Individual module failure could include any one or more of the above.
