ative terminal to terminal “E” and let the motor turn.
2) Disconnect terminal “L” from battery positive terminal and let
the motor stop.
3) Connect terminal “B” to battery positive terminal. Observe
the motor turns once again then stops at a specified position.
4) Repeat Step 1) to 3) several times, and check that the motor
stops at the specified position every time.

CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
