2003 FORD CROWN VICTORIA sensor

The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated. The air bag was designed to inflate
between the door panel and occupant to further enhance the protection
provided occupants in side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side air bags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
Several air bag system
components get hot after
inflation. Do not touch them after
inflation.
If the side air bag has deployed,the air bag will not function
again. The side air bag system (including the seat) must
be inspected and serviced by a qualified technician in
accordance with the vehicle service manual.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrument clusterchapter. Routine maintenance of the
side air bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front air bag system) will either
flash or stay lit.

your vehicle. It is especially useful on slippery and/or hilly road surfaces.
The system operates by detecting and controlling wheel spin. The system
borrows many of the electronic and mechanical elements already present
in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Control
portion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels“search”for optimum traction several times a second and
adjustments are made accordingly.
The Traction Control
system will allow your vehicle to make better use
of available traction on slippery surfaces while you are trying to
accelerate or while your foot is on the accelerator pedal. The system is a
driver aid which makes your vehicle easier to handle primarily on snow
and ice covered roads.
During Traction Control
operation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
“rev-up”when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow
or ice or on a very slippery road
surface, try switching the Traction
Control
system off. This may allow
excess wheel spin to“dig”the
vehicle out and enable a successful
“rocking”maneuver.
The traction control indicator
flashes during a Traction Control

system event.
If the traction control indicator
comes on and stays lit, either:
•the Traction Control
system
requires service, or
•the customer has disabled the system using the traction control switch
located on the left side of the instrument panel.
The Traction Control
system will be on every time you turn the ignition
key from OFF to ON until you deactivate the system using the traction
control switch on the instrument panel left of the steering column.
