    AC / Airbag / Tyre pressure monitor delete on Zafira B

    I am going to use the zafira canbus loom in a kit car and I need to omit the AC / tyre pressure monitoring and the airbags on the network to avoid the dash lights coming on.

    With the air bags, so far from my research, I need to find the right resistors for the system (any ideas) but the other two I am not sure what is the best way to isolate them.

    I have EEPROM reader and OPCOM and a little handy with the electronics.

    Thanks,

      tpms, you can disable the warning light from the instrument cluster itself, then take it off the low speed can

      I may have to get you to explain a little bit more, when I am further ahead with the vehicle. I had the CD30 pass code but thats not the engine pass, so now trying to get the rear electrical centre out of the vehicle to read that eeprom then may be able to get into the system a bit more. Or can I do that above without the pass code?

      Cheers,

      I am just a little nervous as after getting the eprom dump for the CD30, it no longer works!

      Hi Soulman, I managed to read the rear electrical centre eeprom and now have the car pass. Tested it by clearing the ecu and nearly buggering things up!.

      Wondered if you could point me in the direction of how to do the above and remove it from the CAN? I was wondering, what else could be removed from the CAN before the engine ECU stops working?

      Thanks,

      just go through the modules, look at Low Speed CAN settings, anywhere you see it set it to 'Not Present'

      Thanks Soulman will do. I am guessing this wont work with the Airbags? CIM etc? ABS I know I need for the speed signals, unless I can get a transducer to replicate the speed signal.

      Tried that, still getting the symbol on the dash. Same for the air bags, disabled those too. I may, as dont need them, just de solder them on the clocks and live with it.

      have you turned off tpms in the variant config on the cluster?

      airbag lights issues you have to fix the problem, you cant turn them off
