The P0615 fault code refers to a problem with the start signal circuit in your automobile.

When you turn the ignition switch to the START position, a signal is sent to the Body Control Module (BCM) to indicate that the ignition is being started. The BCM then communicates with the Engine Control Module (ECM) to request a crank.

The ECM checks if the clutch pedal is depressed or if the transmission is in Park or Neutral. If these conditions are met, the ECM supplies 12 volts to the control circuit of the starter relay.

This allows battery voltage to flow through the starter relay switch to the starter solenoid, which starts the engine. However, if the ECM detects improper voltage on the control circuit of the starter relay, it will set the P0615 fault code.

This means there is an issue with the start signal circuit, which may prevent the engine from starting properly.

It is important to have this issue diagnosed and repaired to ensure your vehicle starts reliably.
