OP, check out this post (
https://www.crossfireforum.org/forum...sue-alone.html ). I had quite a hard time locating this problem with my car. It gave all the symptoms of the RCM but the RCM was fine. It will not cost you a penny to check it out! My problem was three (3) connectors in the RCM harness that were broken (manufacturing error/defect) right above the pins of the RCM within the connector plugging into the RCM. Check all those one at a time and do not mix them up (take pictures and make sure they go back into the correct locations after you open up those connectors). Inspect the 'cap' where the wire is soldered making sure they are still connected to the wiring/sleeve that marries to the RCM pins. It is ALL outlined in the above post! Let us know the results? Good luck!
