SRS system





Introduction
The safety equipment has been upgraded to further increase the safety of the traveler. This applies to both SRS and SIPS.

Seat belt buckle
The front seat seat belt buckle has new switches (hall sensor type), for safer signal exchange.

SIPS
The SIPS system has undergone major modification both in the area of the deployment mechanism and the SIPS bag itself.
The sensors are electrical and are located in the B posts. When a sensor is activated a signal is sent to the SRS control module which activates the respective SIPS airbag .
The sensor is an independent unit. It consists of a micro processor with an acceleration sensor on a printed circuit board.
The SIPS airbag is a new version. It has a "lower section" which protects the chest and an "upper" section which protects the head from blows. An example of a blow is a collision with a truck or skidding into a tree.

SIPS-function
Activation occurs as follows:
3 ms after the sensor is activated the bag begins to inflate. A detonator ignites an explosive charge (1), pressure increase occurs which presses off a cap at the end of the gas reservoir (3).
Gas from the gas reservoir flows into the mixing section (2) and mixes with the explosive gas, the gas heats up and expands, the lower section of the bag fills up (10ms). The upper section of the bag is inflated as the gas is pressed up from the lower section as it expands (25 ms).

SRS control module
The SRS control module is a new type because the SIPS sensors are connected. The other functions are similar to the other earlier version.

Note! When working with the SIPS bag take the same precautions as when working on the SRS system. Always remove the battery lead before commencing work. The SRS module has reserve voltage for 10 seconds.

Diagnostics
The diagnostic system has 70 codes.
