Ford Galaxy / Ford S-MAX. Manual — part 964

Continued use of the side impact sensor is permissible provided it has not been physically
damaged and it passes a self-test.

Driver Air Bag Module, Driver Lower Air Bag Module and Passenger Air Bag Module

The driver, driver lower and passenger air bag modules are all single-stage air bags.

New Driver Air Bag Module design introduced for vehicles build 13.07.2009 onwards. New
Air Bags require a revised removal instruction. See Removal And Installation procedure for
details.

Clockspring

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

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.

After installing a PAD switch kit, the RCM must be re-configured using WDS.

Side Air Curtains

The side air curtain modules are located in the roof rail between the A-pillar and D-pillar.
They are attached to the upper part of the side panel and are hidden behind the vehicle
trim panels.

The electrical connector for the 5-door is located between the C-pillar and D-pillar. The
electrical connector for the Wagon is located above the B-pillar.

In the event of a side impact the relevant side air curtain is deployed and forms a
protective cushion between the corresponding side window and the head of the person(s)
sat on the front and rear seat.

The side air curtains are deployed simultaneously with the side air bags.

Side Air Bag

The side air bags are incorporated in the front seat backrests; a sewn-on label on the
respective backrest indicates the vehicle is equipped with side air bag modules.

When a side air bag is deployed, the seam of the seat cover tears open enabling the side
air bag to inflate unhindered from the front seat backrest.

Safety Belt Retractor and Pretensioners

The pyrotechnic pretensioners for the driver and front passenger safety belts are
incorporated into the safety belt retractors.

In the event of a collision, the safety belt pretensioners can be deployed in one of two
ways:

On their own.
Simultaneously with the front air bag module(s).

The driver and front passenger safety belt buckles have a switch for the safety belt
monitoring facility, which is required by law in some markets.

Diagnosing Customer Concerns Without Hard DTCs

WARNING: To avoid accidental deployment, the restraints control module (RCM)

backup power supply must be depleted. Wait at least one minute after disconnecting the
battery ground cable(s) before commencing any repair or adjustment to the SRS, or any
component(s) adjacent to the SRS sensors. Failure to follow these instructions may result
in personal injury.
NOTE: Following the pinpoint tests when a diagnostic trouble code (DTC) is not present,
or the air bag warning lamp is not permanently illuminated, will result in needless
replacement of air bag system components and repeat repairs.

Speak with the customer to determine if a particular set of conditions must be met in order
for a fault to occur. If an illuminated air bag warning lamp is reported by the customer but
is not present when the vehicle comes in for repair, pinpoint test diagnostics cannot be
used.

Diagnosing Customer Concerns with Hard DTCs

WARNING: Do not use substitute air bag simulators when working on the SRS. Use

only the appropriate tool. Failure to follow these instructions may result in personal
injury.
