Power is supplied to the crash sensor by the RCM.
If a crash sensor fails, the RCM stores a Diagnostic
Trouble Code (DTC) .
Continued use of the crash sensor is permissible
provided it has not been physically damaged and
it passes a self-test.
The external shape of the crash sensor prevents
it from being installed incorrectly.
Side Impact Sensors
E82299
The side impact sensors are located at the bottom
of the B-pillars and transmit digitally encoded
acceleration information to the RCM.
Continued use of the side impact sensor is
permissible provided it has not been physically
damaged and it passes a self-test.
Driver and Passenger Air Bag Modules
E51936
The driver and passenger air bags are single-stage
air bags.
Clockspring
E55880
The clockspring is designed to carry signals
between the RCM and the driver air bag module.
The clockspring is installed on the steering column,
and consists of fixed and moving parts connected
by a coiled Mylar tape with internal conducting
tracks. The Mylar tape is able to 'wind up' and
'unwind' as the steering wheel is rotated,
maintaining electrical contact at all times between
the RCM and the driver air bag module.
Vehicles with stability assist have a steering wheel
rotation sensor as an integral part of the
clockspring.
Passenger Air Bag Deactivation
E51996
A passenger air bag deactivation (PAD) switch can
be fitted by the dealer as an optional extra; the
PAD switch is installed in the glove box. The driver
can operate the PAD switch with a key to
deactivate the passenger air bag module.
When the ignition is switched on, a warning lamp
in the instrument panel indicates to the driver and
passenger that the passenger air bag module has
been deactivated.
