Read Very carefully!!
connections to be made to the airbag ecu plug!
Pin 47.....wire number CC4............ connect to +12 of timer board
ground/car body............................connect to -12v of timer board
Connect all three of these to one wire and connect to O/C of the timer board
Pin 48.....wire number 6548...........
Pin2........wire number 6541A.........
Pin40......wire number 6541B.........
VERY IMPORTANT
remove the shorting link at plug pin 26-27 this shorts pins 1-2 together
push down on the centre tab and push out
if you don't remove this the airbag light will stay on permanently!
leave Airbag ECU unplugged
test by turning on the ignition the airbag+sidebag light should go out after a timed delay
to adjust the time the lights stays on, adjust the pot on the board to extend or shorten the time
important info for testing this system!
Pin 49.....wire number 6547...........from passenger bag key sw
Pin 50.....wire number 6546...........from passenger bag key sw
switch resistance ON= 100ohms , OFF=400ohms
Pin6.........wire 6507.......lower front RH side airbag
Pin7.........wire 6506.......lower front RH side airbag
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
Pin10........wire 6508.......lower front LH side airbag
Pin11.......wire 6509.......lower front LH side airbag
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
Pin18.......wire 6502.......passenger airbag
Pin19.......wire 6503.......passenger airbag
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
Pin20.......wire 6538.......Driver's air bag
Pin21.......wire 6539.......Driver's air bag
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
Pin22.......wire 650.........pretensioning seat belt (driver's side)
Pin23.......wire 651.........pretensioning seat belt (driver's side)
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
Pin24.......wire 652.........pretensioning seat belt (passenger side)
Pin25.......wire 653.........pretensioning seat belt (passenger side)
resistance 2.1ohms measured at airbag ecu (shorting pins defeated)
when i say with the shorting pins defeated!
if you look at the plug you have double holes above single holes
when the plug is unplugged from the ecu the double holes short the single holes below protecting the airbags from stray voltages stopping static setting the bag off
Safety feature!
