Guide: MOT Faulty airbag bypass
#1
WARNING THIS WILL LEAVE YOU WITH A NON WORKING AIRBAG SYSTEM

Phase 3 HDI with a faulty airbag system and unable to rectify problems
Caution! check if your car has the same system as different systems are fitted to the same modle car!!!!!!

   

this is a cheap guide on how to trick the Airbag diag lights for MOT

this is how i would do this at quick notice with limited parts available

Parts needed
delay on or off timer

i have used a timer from Maplins for this as its all i could find at short notice
unfortunately the timer dose not do quite what i wanted it to do so have slightly modified it

the timer comes in a kit you have to assemble!
Maplins kit 555 Monostable Switch Kit N32FL
http://www.maplin.co.uk/555-monostable-s...kit-220009

[Image: n32fl.jpg]

you will need one extra capacitor 10uF 50v and some wire

solder up the kit as instructed
add the capacitor across pins 1 -2 of the chip, pin 1 is 0v or - if the capacitor is polarised!
adding this mod makes the timer start the delay as soon as you power up
as the circuit std needs the board powered and then triggered with a button

add a length of wire between the 0v feed and the common of the relay output
this addition is part of the wiring for the airbag lights Wink
