5. Before maintenance, wait for 60 seconds or 

more after the disconnection of the battery (

−) 

terminal. Wrap the disconnected (

−) terminal 

with tape for insulation. The condenser inside 
SRS-ECU keeps a voltage necessary to 
expand the air bag for a certain period even 
after the IG power is turned OFF. Therefore, if 
any operation is performed before the period 
elapses, it may cause serious damage.

6. If the influence of heat is suspected during 

painting work, remove the following parts:

• 93°C or higher SRS-ECU, air bag module, 

clock spring, front impact sensor, side impact 
sensor

• 90 °C or higher Seat belt with pre-tensioner

7. After the maintenance of the SRS air bag and 

seat belt with pre-tensioner is completed, be 
sure to delete the diagnosis code and check 
whether the SRS warning lamp lights up (refer 
to 

P.52B-12

).

31, 32

Floor wiring harness 

→ front passenger's seat belt 

pre-tensioner

Repair or replace the floor wiring 
harness.
