DANGER

After disconnecting the battery cable, wait 60 
seconds or more before proceeding with the 
following work. In addition, insulate the 
negative battery terminal with a tape. The 
condenser inside the SRS-ECU is designed 

to retain enough voltage to deploy the air 
bag for a short time even after the battery

has been disconnected, so serious injury 
may result from unintended air bag 
deployment if work is done on the SRS 
system immediately after the battery cables 
are disconnected.

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.

1. SRS-ECU, air bag modules, clock spring, 

impact sensors: 93

°C or more

2. Seat belt with pre-tensioner: 90

°C or more

• Whenever you finish servicing the SRS, 

always erase the diagnosis code and check 
warning lamp operation to make sure that the 
system functions properly.

•

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.
