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.
