What Happens If the PCM Power Relay Fails Open or Closed?

What Happens If the PCM Power Relay Fails Open or Closed?

When a PCM power relay fails, your engine “brain” either loses power completely or stays powered when it should be off. In both cases, vehicles become unreliable, diagnostics get messy, and procurement teams face urgent replacement needs from trusted suppliers and manufacturers. Understanding exactly what happens in an open vs. closed failure helps engineers, buyers, and wholesalers […]
