least 60 seconds.
(g) Clear the DTCs stored in memory (see page 05-1215).
(h) Turn the ignition switch to the LOCK position.
(i) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(j) Check the DTCs (see page 05-1215).

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).
