S60 AWD L5-2.5L Turbo VIN 59 B5254T2 (2005)
A function known as multi-point detection is used during a headon collision. This means that the impact pulse is registered in several points. This
function is integrated in the supplemental restraint system module (SRS) (4/9). The front impact sensors (7/178 and 7/179) (certain markets and models
only) is also part of multi-point detection in the control module. The front impact sensors register the impact pulse and send acceleration data to the
control module.
When the collision pulse is sufficiently large an activation signal (current pulse) is transmitted to one or more of the following:
-
front airbags stages 1 and 2 (8/30, 8/31, 8/32 and 8/61)
-
front airbags stage 3 (8/123 and 8/124) (XC90 USA/CDN only)
