AIR BAG SYSTEM

T97

After Activation

1. Directly after the activation of the pre-tensioner seat belt system and the application of a load to the seat belt in

the direction of withdrawal, the ELR lock mechanism operates and the pawl engages the housing gear.

2. When a larger than specified load is applied to the seat belt with the locking base locked by the pawl, the

torsion bar twists. Thus the spool rotates and the belt webbing is withdrawn.

3. Because the spool rotates in the direction of withdrawal, the ring gear pushes the balls back and the pinion is

disengaged from the ring gear.

ON-BOARD DIAGNOSTIC FUNCTION

A6E813001046T04

Outline

• The on-board diagnostic function consists of the following functions: a failure detection function, which detects

malfunctions in the air bag system-related parts; a memory function, which stores detected DTCs; a self-

malfunction diagnostic function, which indicates system malfunctions using DTCs; a PID/data monitoring

function, which reads out specific input/output signals; and, an active command mode function, which actively

controls the operation of output parts.

• Using an SST (WDS or equivalent), DTCs can be read out and deleted, and the PID/data monitoring function

and active command mode function can be activated.

• A fail-safe function, which prevents the abrupt activation of the air bag module and the pre-tensioned seat belt

in case of an air bag system malfunction, is included.

• The failure detection function, memory function, and fail-safe function are the same as that of the 626 (GF)

model.
