    95 Disco resetting reading SRS(airbag codes)

    Hey all, It finally time for me to give back to the Land Rover forum help world.
    Ive been fighting with a SRS light on the dash for a number of years and FINALLY got around to fixing it. And Im going to pass this on to all the poor souls that are stuck with a pre ODBII system.
    Tools needed. Hawkeye Total reader, and BA5077 adapter for Airbags. Your thinking WTF Fat! I cant plug this in to my system I don't have a ODBII port!
    Well we are going to make ONE! So grab a ODBII plug with pig tail from Amazon or some one else. Next find a plug that will work with the Airbag Diagnostic port. Its a square 4 pin plug look under your dash and it might still have one attached. If not get a scrap Ignition lock and pull it off of that one.
    Pin out is as follows. pin 16 is 12V put a 2 amp fuse on it just incase.
    Pin 4 goes to ground on the body.
    Pin 14 goes to the upper left of the 4 pin to Yellow Pink
    Pin 13 goes to the upper right pin Yellow Green
    Pin 5 goes to lower left.





    Like so.. Here is a shot of the whole adapter.


    Once done making the cable, attach it in the rover, You can get power for it from the fuse box spade port 1, this gives power when the system is keyed on.
    Attach the BA5077 adapter, which is just a pin shifter, that moves the reading pins from 15 and 7 to 13 and 14, which is the layout on the 96 forward DI's.
    Attach the Hawkeye turn on ignition and read the DTC's then clear them. You will need to select the TRW MPS version. Mine was reporting a mem error and that what flagged it on for all these years.

    So I hope this helps out another owner with the 95 system, I see there are a few of us out there with SRS lights on. And now finally a way to fix it with out having to go to the dealership to hook up the testbook to it.

    Cheers

    Hi
    I have the same issue with a 1995 Range Rover classic, it has the same diagnostic plug under the dash.

    You mention a pin shifter adaptor for 96 on wiring, you also state, this will help owners of 95 year cars, will i need that as mine is 1995 ?

    kind regards Dan

    here is the info on the pin shifter thats needed. Yes the 95 RR and 95 Disco should be the same unit.
