P0615 Starter Relay Circuit

What does P0615 Starter Relay Circuit mean?

The P0615 code, also known as the Starter Relay Circuit code, is a generic diagnostic trouble code that can affect many OBD-II vehicles.

This code is associated with a malfunction in the starter relay circuit, which is responsible for providing power to the starter to crank the engine and start the vehicle.

If your vehicle has this code, it may not start at all or experience sporadic no-crank occurrences.

Common causes of this code can include a faulty ignition switch, defective starter relay, blown fuse, corroded or damaged connectors, or a faulty PCM.

To diagnose and repair this issue, it is important to consult technical service bulletins for your specific vehicle and perform visual inspections of the circuit components, including wiring, connectors, and connections.

Advanced steps may require the use of a digital multimeter and specific technical references.

Some common repairs for this code can include replacing the ignition switch, blown fuse, cleaning corrosion from connectors, repairing or replacing wiring, or replacing the starter relay.

It is crucial to prioritize the specific technical data and service bulletins for your vehicle.

Troubleshooting P0615 error code

1. Research the Technical Service Bulletins (TSBu0027s) for the specific vehicle by year, model and power plant
2. Check if a fuse is incorporated into the starter relay circuit and see if it is blown if applicable
3. Perform a thorough visual inspection of all components associated with the starter relay circuit
4. Check connectors and connections for security, corrosion and damaged pins
5. Perform voltage checks on the battery and starter
6. Perform continuity testing to check the integrity of the wiring, ignition switch, and other components
7. Repair or replace faulty components such as the ignition switch, fuse, wiring, battery cables, starter relay, starter, or PCM
