The security light in the dash "Theft" is flashing rapidly when the key is on. The truck will not start. I am told I have to reprogram the key system. I was asked if I replaced the ECM. Where is the ECM? Is there a way to test it before replacing? Can you walk me through the procedure to reprogram the key? How do I tell what PAT's system my truck has?
have the same problem?
