• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not enough, reform the terminal to
increase contact tension or replace it.
Special tool
(A): 09932–76010 Connector test adapter kit
• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could
cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.
Repair and Inspection Required after AccidentS6RW0D8204048
CAUTION!
• All air bag system components, including
the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from
another vehicle.
• Do not attempt to service the parts below.
Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator)
modules
– Driver / Passenger side-air bag (inflator)
modules
– Driver / Passenger side curtain-air bag
(inflator) modules
– Driver / Passenger seat belt
pretensioners
– Forward impact-sensor
– Driver / Passenger side impact-sensors
–SDM
– Contact coil and combination switch
assembly
– Air bag wire harness in main harness,
instrument panel harness, floor harness,
passenger air bag harness, side-air bag
harness and side curtain-air bag
harness.
• Proper operation of the sensors and air
bag system requires that any repairs to the
vehicle structure return it to its original
production configuration.
