.

To enhance the system reliability, a connector short 
circuiting mechanism is integrated in the SRS-ECU 
connector, air bag module connectors, clock spring 
connector, pre-tensioner connectors, and intermedi-
ate connector between curtain air bag module and 
SRS-ECU (black connector "A" shown in the figure).

CONNECTOR SHORT-CIRCUIT MECHANISM

This mechanism prevents the improper deployment 
of air bag module because of the current application 
to the squib due to the static electricity when connec-
tors between SRS-ECU and air bag modules 
(squibs) are disconnected. When the connector is 
disconnected, the short spring short circuits the 
power supply side terminal and ground side terminal 
of squibs, and prevents the static electricity from 
generating the potential difference. This connector 
mechanism is adopted for the following connectors.

• SRS-ECU connector

• Connector between the clock spring and 

body-side wiring harness

• Each air bag module connector

• Each pre-tensioner connector

• Intermediate connector between curtain air bag 

module and SRS-ECU

GENERAL INFORMATION

M2222000200012

For the manual transaxle, newly developed W5M6A 
has been adopted. The transaxle offers the following 
features.

• The width of each gear tooth is increased to 

achieve the high torque capacity suitable for 
4B11 engine. At the same time, the increase of 
transaxle length is kept minimum, securing the 
same length as the conventional 6-speed tran-
saxle.

• The synchronization mechanism from 1st to 5th 

gear has been multi-synchronized to improve the 
durability.
