SERVICE PRECAUTIONS

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-7

CAUTION

The SRS components and seat belt with
pre-tensioner should not be subjected to heat, so
remove the SRS-ECU, driver’s and front
passenger’s air bag modules, clock spring, side
air bag modules, and seat belt pre-tensioner
before drying or baking the vehicle after painting.

•

SRS-ECU, air bag modules, clock spring,
impact sensors: 93

°

C or more

•

Seat belt with pre-tensioner: 90

°

C or more

CAUTION

Whenever you finish servicing the SRS, always
erase the diagnosis code and check warning
lamp operation to make sure that the system
functions properly.

CAUTION

If checks are carried out by using the SRS-ECU
harness connector, observe the following
procedures: Insert the special tool (probe in the
harness set) MB991222 into connector from
harness side (rear side), and connect the tester
to this probe. If any tool than special tool is used,
damage to the harness and other components
will result. Never insert the probe directly to the
terminals from the front of the connector. The
terminals are plated to increase their
conductivity, so that if they are touched directly
by the probe, the plating may break, which will
cause drops in reliability.
