When this circuit is operating correctly, it ensures that power is supplied to the ECM and fuel injectors when the ignition key is turned on, allowing the engine to start and run smoothly. However, when the circuit is detected as low, it means that there is a malfunction or a short circuit that is preventing the relay from functioning properly.
