Airbag
Warning Light - Flashing Codes
CAUTION / WARNING - Airbags are extremely dangerous if not properly
respected. For this reason any fault with the system should be corrected
by a qualified auto-electrician. Even simple probing of the airbag
connectors with a voltmeter can cause airbag deployment.
Mondeo's
use colour coded wiring for the airbag system, although you should
never take it as certain, any wiring found wrapped in a yellow sleeve
or terminating in a yellow connector block should be assumed to
be part of the airbag system.
The
airbag warning light should come on with the ignition and remain
lit for 5 seconds. After this period it should go out and not illuminate
again until next time the ignition is turned on. If the light fails
to come on then check the fuse for the system and then the bulb
in the instrument cluster. If a problem is detected with the system
then it will be indicated by a number of flashes. If more the one
code is detected the system will assign priority and display the
most important first.

Common
Fault:
The
airbag warning light flashing 4 times is a common fault on late
Mk1 and all Mk2 mondeo's using the pyrotechnic pretensioners - especially
if you have recently moved the position of one of the front seats.
Turn the igntion off and allow the car to sit for 15 minutes. Underneath
the front seat base, (access is best from the rear passenger footwells,
with front seats furthest forward), you will find two cables wrapped
in yellow sleeving. The yellow connector may have parted company
with its other half - Even if it hasn't disconnect and reconnect
it to ensure that it is secure. Move on to the passenger side and
check the wiring there - whilst doing this ensure the cabling is
slack and not badly routed resulting in it being pulled tight.
