(1) Removal of passenger’s airbag module (Refer to )
)(2) Securing of passenger’s airbag module
(a) Connect the SST (98299FJ000) and the passenger’s airbag module connector, and lock it securely.
SST
98299FJ000 (test harness adapter AM)
(b) Using wiring harnesses (with a core (A in the figure) of 1.25 mm2 {0.00194 sq in} or more), secure the passenger’s airbag module to the tire.
WARNING:
Strictly follow the two instructions below. Otherwise, serious damage might be caused due to flying debris of the activated passenger’s airbag module or tire, etc.
·When activating the passenger’s airbag module, a force of approx. 1 t is applied on the wiring harnesses. Therefore, secure the module tightly with triple wiring harnesses without slack.
·As shown in the figure, be sure to install the passenger’s airbag module with the deploying side facing the center of the tire.
·As shown in the figure, be sure to install the passenger’s airbag module with the deploying side facing the center of the tire.
CAUTION:
Use waste tires for disposal operation.
