component. Failure to do this may result in accidental air
bag deployment and possible personal injury. Refer to
DISABLING & ACTIVATING AIR BAG SYSTEM .
* For about 60 seconds after air bag system is disabled, it
retains enough voltage to deploy air bags. After disabling
system, wait at least 60 seconds before servicing.
* After servicing, always turn ignition on from passenger-side
of vehicle in case of accidental air bag deployment.
* After servicing, check SRS warning light to verify system
operation. See SYSTEM OPERATION CHECK.
* Always wear safety glasses when servicing or handling an
air bag.
* The SRS-ECU must be stored in its original special container
until used for service. It must be stored in a clean, dry
place, away from sources of extreme heat, sparks and high
electrical energy.
* DO NOT expose air bag module and clockspring to temperatures
greater than 200
F (93C).
* When placing a live air bag module on a bench or other
surface, always face air bag module and trim cover up, away
from surface. This will reduce motion of module if air bag
accidentally deploys.
* After air bag deploys, air bag surface may contain deposits
of sodium hydroxide, which irritates skin. Always wear
safety glasses, rubber gloves and long-sleeved shirt during
clean-up. Wash hands using mild soap and water. Follow
correct clean-up and disposal procedures. Refer to
DISPOSAL PROCEDURES .
* Because of critical system operating requirements, DO NOT
service any SRS components. Repairs are only made by
replacing defective part(s).
* DO NOT allow any electrical source near inflator on the back
of air bag module.
* When carrying a live (undeployed) air bag module, trim cover
must be pointed away from body to minimize injury in case of
accidental air bag deployment.
* DO NOT probe wire harness connector terminals. Instead, use
SRS Check Harness (MB991530).
* DO NOT probe a wire through insulator, as this will damage
it and eventually cause failure due to corrosion.
* When performing electrical tests, prevent accidental
shorting of terminals. Such shorts can damage fuses or
components and may cause a second fault code to set, making
diagnosis of original problem more difficult.
* Never use an analog volt/ohm meter or test light in place of
a Digital Volt/Ohm Meter (DVOM). Use only a DVOM with a
maximum test current of 2 mA (milliamps) at minimum range of
resistance measurement. Also see SPECIAL TOOLS.
* If SRS is not fully functional for any reason, DO NOT drive
vehicle until system is repaired and is fully functional. DO
NOT remove bulbs, modules, sensors or other components, or
in any way disable system from operating normally. If SRS is
not functional, park vehicle until repairs are made.
SPECIAL TOOLS
To avoid air bag deployment when working on SRS, DO NOT use
electrical test equipment such as test lights, battery or A/C-powered
volt/ohmmeter, or any type of electrical equipment other than those
specified by manufacturer. See SRS RECOMMENDED TOOLS table.

CALIPERS
You are not required to replace or rebuild calipers in axle
sets. However, when replacing or rebuilding a caliper due to the
conditions that follow, you may suggest servicing, rebuilding, or
replacement of the other caliper (on the same axle) for improved
performance and preventive maintenance (for example, the part is close
to the end of its useful life, replacing the caliper may extend pad
life, or contribute to more balanced braking).
CAUTION: When installing loaded calipers, it is required that
friction material be matched in axle sets for consistent
braking characteristics.
