The P0615 fault code indicates an issue with the starter relay circuit in a vehicle. This system plays a crucial role in the operation of the vehicle's starting mechanism. When the starter relay functions properly, it allows electrical current to flow from the battery to the starter motor, enabling the engine to start. Problems in this circuit can lead to starting difficulties or complete failure to start.

What are the symptoms of the P0615 code?

Symptoms that may indicate a problem with the starter relay circuit include:

• Engine does not crank or start when the key is turned
• Intermittent starting issues, where the vehicle starts sometimes but not others
• Clicking sound from the starter area when attempting to start
• Dashboard warning lights illuminated, particularly the check engine light
• No response from the starter when the ignition is engaged

What causes the P0615 code?

Several factors can lead to triggers in the starter relay circuit fault code, including:

• Defective starter relay
• Faulty ignition switch
• Damaged wiring or connectors in the starter circuit
• Issues with the battery or battery connections
• Problems with the engine control unit (ECU)
• Corrosion or poor grounds in the electrical system

How to fix P0615?

To resolve the P0615 fault code, the following steps may be taken:

• Inspect and replace the starter relay if faulty.
• Test the ignition switch for proper operation and replace if necessary.
