Update I got the RCM put back in and as soon as I plugged in the battery the hazards or running lights were flashing but no indication on dash that the hazards or anything was on. I started the car and it stopped, however my initial problems still persist. I am planning on checking the ohms of the CAN BUS circuit at the PCM C4 connector but if all is well there, not sure if I should move towards SLA or Conductor plate?
