REMOVAL
WARNING:
-
To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing
any front or side air bag Supplemental Restraint System (SRS) components and before servicing, replacing, adjusting or striking
components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
-
The air bag Electronic Crash Sensor (ECS) module orientation is critical for correct system operation. If a vehicle equipped with an air
bag supplemental restraint system (SRS) has been involved in a collision in which the right cowl A-pillar area has been damaged, inspect
the mounting and bracket for deformation. If damaged, the ECS must be replaced whether or not the air bags have deployed. In addition,
make sure the area of the ECS mounting is restored to its original condition.
The side air bag sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary
batteries and power supplier (if equipped).
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.
NOTE: The safing sensor is internal to the air bag electronic crash sensor (ECS) module and is not replaced separately.
1. Disconnect the battery ground cable(s) and wait at least one minute.
2. Remove the RH cowl side trim panel.
