How do you know if the pcm relay is bad?

To determine if the PCM relay is bad, you can perform a few checks. First, listen for clicking sounds when the ignition is turned on, which indicates the relay is functioning. Next, use a multimeter to test for continuity across the relay terminals; a lack of continuity suggests a faulty relay. Additionally, if you experience issues like the engine not starting or intermittent electrical problems, it may be a sign that the PCM relay needs replacement.
