Pcm power relay.

To function properly, a relay supplies power to the PCM through voltage signals from the battery, ground signals, and ignition switch input signals. Therefore, it is normal for the relay coil control circuit to have a low voltage. The PCM’s fault detection circuit detects voltage from the relay when you see trouble code P0685.
