Air Bag Control Module: Service and Repair
Restraints Control Module (RCM)
Removal
WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas
for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed
whether or not the air bags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM
is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R)
and cause serious personal injury or death.
NOTICE: When installing a new Restraints Control Module (RCM), it is necessary to carry out Programmable Module Installation (PMI).
System failure may occur if PMI is not performed. See: Powertrain Management/Computers and Control Systems/Information Bus/Testing and
Inspection/Programming and Relearning
NOTE: When installing a new Restraints Control Module (RCM) always make sure the correct RCM is being installed. If an incorrect RCM is installed,
erroneous DTCs will result.
NOTE: The air bag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
1. If installing a new RCM, carry out the steps necessary to prepare for Programmable Module Installation (PMI). See: Powertrain
Management/Computers and Control Systems/Information Bus/Testing and Inspection/Programming and Relearning
2. Depower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering See: Air Bag
Systems/Air Bag(s) Arming and Disarming/Service and Repair/Supplemental Restraint System (SRS) Depowering and Repowering in the General
Procedures.
