WARNING
•
Inspection of the SRS-ECU connector harness
should be carried out by the following procedure.
Insert the backprobing tool into connector from
harness side (rear side), and connect the tester to
backprobing tool. If any tool other than backprob-
ing tool is used, it may cause damage to the har-
ness and other components. Furthermore,
measurement should not be carried out by touch-
ing the backprobing tool directly against the termi-
nals from the front of the connector. The terminals
are plated to increase their conductivity, so if they
are touched directly by the backprobing tool, the
plating may break, which will decrease reliability.
•
The SRS components and seat belt with
pre-tensioner should not be subjected to heat, so
remove the SRS-ECU, driver’s and front passen-
ger’s air bag modules, clock spring, side-airbag
modules, and seat belt pre-tensioner before drying
or baking the vehicle after painting.
