Trouble code 55 on a 1991 Plymouth Acclaim indicates that the engine control module (ECM) has completed its self-diagnostic tests and found no faults. This code is often referred to as a "completion code," signaling that the system is functioning normally. It typically appears after running the diagnostic test and is not indicative of any specific issue. If you're troubleshooting, it's a sign that there are no stored fault codes in the system at that time.
