    Help with multi control module issues

    Hello all,

    A little history first

    2008 sport 150,000 + miles very well maintained, in the last year I've replaced all 4 air springs and the compressor. The compressor was a aftermarket replacement, the original one seemed good (still have it) just changed it since I was doing the air springs. The problem I'm having is the yellow/red arrows with the car in the middle warning. When I scan with my ILAND I get multiple module faults, RLM, ARCM,BCM all communication errors. Where do I start? I cannot do a suspension height calibration since it says it won't communicate. Thanks

    So after checking and finding no corrosion on any connectors I can only assume a module is bad. I spoke with ILAND tech support and after loading the app again I still had a communication error. I hate he thought of going to the dealer only to have them change a simple module and charge me .

    Update,

    Playing around with things I was able to adjust the suspension height calibration, not 100% perfect but very close. Took about 10 times of entering fake measurements to trick the system to accept. All codes still active.
