Section 5 (Air Bag Restraint Systems): Diagnostics: Notes
WARNING: This page is about a different car, the 2000 Dodge Intrepid, 2000 Chrysler LHS, 2000 Chrysler Intrepid, 2000 Chrysler Concorde, and 2000 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Always follow air bag service precautions to avoid air bag deployment and possible personal injury. Refer to procedure under See AIR BAG SAFETY PRECAUTIONS
. After component replacement, ensure proper system operation. See SYSTEM OPERATION CHECK
.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See Computer Relearn Procedures in the Reference Information section.
NOTE:
Although other scan tools are available, manufacturer recommends using Diagnostic Readout Box (DRB) tester to access SRS on-board diagnostics. Following diagnosis and testing procedures are designed for use with DRB.
SRS is monitored by Occupant Restraint Controller/Air Bag Control Module (ORC/ACM). ORC/ACM contains safing sensor, an integral sensor in circuitry of system, which is used to deploy air bag modules.
ORC/ACM monitors critical input and output circuits within air bag system, ensuring they operate correctly. Some circuits are tested continuously; others are checked under certain conditions. ORC/ACM provides information about air bag system, through AIR BAG warning light and DRB tester. Each circuit monitored by ORC/ACM has a corresponding fault code (fault message) assigned to it.
