System Structure
The following components form part of the
supplemental restraint system (SRS):
• RCM
• Single-stage driver and passenger air bag
modules
• Side air bag modules
• Side air curtain modules - except vehicles with
convertible top
• Crash sensor
• Side impact sensors
• Clockspring
• Front safety belts with front safety belt buckle
switch on driver side and front safety belt
pretensioners
• Safety belt retractors
• Air bag warning indicator
• Passenger Air Bag Deactivation (PAD) switch
(optional)
• Roll over protection unit - vehicles with
convertible top
RCM
E42449
The RCM is located under the floor console, near
to the gearshift lever. Installation marks on the
module are to make sure it is aligned correctly.
Micromechanical sensors are incorporated into the
RCM; this measures the vehicle's
acceleration/deceleration in the event of a collision.
The calculated value is evaluated by the RCM to
determine the severity of the impact.
The RCM compares the values it receives from the
crash sensor (if equipped), the side impact sensors
and the internal micromechanical sensors. If the
deceleration due to a frontal or side impact exceeds
a stored value then the RCM triggers the air bag
modules and safety belt pretensioners as required.
If the vehicle battery is destroyed in the collision,
a voltage hold circuit in the RCM will still enable
the air bag modules to be triggered up to 150 ms
after the start of the impact.
If a system fault is detected by the RCM, the air
bag warning lamp is illuminated. The fault can be
located by carrying out a diagnostics check using
the Worldwide Diagnostic System (WDS).
The RCM can be used again after a collision for
up to 5 times, provided that the RCM is not
physically damaged and that it passes a self-test.
The air bag modules are triggered by a direct
current signal.
Crash Sensor - Vehicles built up to
05/2005
E42452
All vehicles, except vehicles with a convertible top,
built 05/2005 onwards are not equipped with a
crash sensor.
The crash sensor is installed at the front of the
vehicle, behind the radiator grille. Data from the
crash sensor is evaluated by the RCM to assess
the severity of a frontal impact. The crash sensor
transmits digitally encoded acceleration information
to the RCM.
