then remover the cover on the rcm and watch the relays ,,,close them by hand and then u will know which is bad.
then send it to tighted 1 and have him fix it, you may think u know this car but none of us know all about it . example tighted 1 knows the rcm,,,i know the rear end, others know other parts a lot of us have tried to repair the rcm and wind up sending it to tighted 1 good luck jim

we had this problem come into our shop twice so far ,,both were rcm
