USE SIMULATION METHOD TO CHECK
HINT:

Before performing the simulation method, check that the airbag sensor assy center is in check mode
(see page 05-1218).

Perform the simulation method by selecting the check mode with the hand-held tester (see page
05-1218).

After selecting the check mode, perform the simulation method by wiggling each connector of the air-
bag system or driving the vehicle on a city or rough road (see page 05-1218).
