XJ6R – Air Bag Module Wiring
Following from the earlier success, I put the battery on charge which then limited further testing. The airbag module testing was complete however I had to make a choice. Modify the Air Bag Module (ABM) or build a circuit to fake the signal required. I decided that the quickest way to resolve the ABM output signal requirement was to hard wire the connections as if the airbags and impact sensors were connected. I will find a space for the ABM somewhere in the drivers side dash. Maybe to the right of the foot well just above the sill and under the air intake. I have put a second fuse box in that space on the passenger side.
I printed out the connector pin outs and drew the various links needed. This reminded me of having to do updates to circuit boards years ago but my eyesight was much better then! I still need to add the resistors to simulate the Airbags. There are no suitable resistors in my spares box so I will order some ASAP.
The blue wires are those I added to the module as drawn in above
The loom is much simpler now. The original loom is used with the unused wires removed. Only one of the two plugs are needed now so I will use the empty plug to fill the open socket and seal the wire entries with some sealant or glue.
The following wires are needed:
- Two ground connections that go into 1 after a few inches
- Continuous +B power
- Switched +B power (ignition switch position 1)
- Air Bag module signal output
I just need to order the resistors to finish the job.
