6. Inspection of the SRS-ECU harness connector <vehicles with SRS side air bag> should be carried

out by the following procedure.

Insert the special tool (narrow probe in the harness set) into connector from harness side (rear side),

and connect the tester to this probe. If any to other than the special tool is used, it may cause

damage to the harness and other components. Furthermore, measurement should not be carried

out by touching the probe directly against 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.

7. SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove the

SRS-ECU, air bag module (driver’s side and front passenger’s side), clock spring, side impact sensor,

front seat assembly (side air bag module), and seat belt with pre-tensioner before drying or baking

the vehicle after painting.

SRS-ECU, air bag module, clock spring, side impact sensor: 93

C or more

Seat belt with pre-tensioner: 90

C or more

8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system

functions properly. (Refer to GROUP 52B.)

9. Make certain that the ignition switch is OFF when the MUT-

is connected or disconnected.

10. If you have any questions about the SRS, please contact your local distributor.

NOTE

SERIOUS INJURY CAN RESULT FROM UNINTENDED AIR BAG DEPLOYMENT, SO USE ONLY

THE PROCEDURES AND EQUIPMENT SPECIFIED IN THIS MANUAL.
