 Structure and Operation

•

The steering gear is joined to the steering shaft through the intermediate shaft.

•

In a collision, the intermediate shaft is crushed as the steering gear moves rearward, thereby absorbing the 
impact.

•

If the driver’s body hits the steering wheel, the force applied to the steering wheel is transmitted through the 
inner shaft, outer column, and fixing bracket. As a result, the fixing bracket is disengaged from the dashboard, 
and the whole steering shaft will move forward.
At this moment, the U-shaped plate, which is fixed to the dashboard at one end and held by the fixing bracket 
at the other, will deform and absorb the impact.

OUTLINE OF CONSTRUCTION

A6E690201020T01

•

The construction and operation of the conventional braking system is essentially carried over from that of the 
626 (GF), except for the following features and specifications. (See 626 Training Manual 3303-10-97D.)

•

The construction and operation of the ABS/TCS/DSC and on-board diagnosis system is essentially carried 
over from that of the current 323 (BJ), except for the following features. (See 323 Workshop Manual 
Supplement 1704-1*-00J.)
