P0615 - STARTER RELAY CIRCUIT

The starter relay circuit sends a series of voltage signals to the starter so that it starts the engine and at the same time the vehicle can be started. In the starter relay circuit act several components such as the battery, the ignition switch, fuses, starter solenoids, as well as a series of sensors.

When the PCM (Powertrain Control Module) identifies faults in any of the ignition switch circuit components, the fault code P0615 OBD2 will be set. This kind of generic code is also often accompanied by other codes, which are set when a malfunction is detected in the ignition relay circuit.

• Check Engine light ON.
• The motor will not start.
• The vehicle starts in the neutral position.

Reasons for setting the P0615 OBDII diagnostic code:

• The battery may not have the proper voltage level.
• A fuse may be blown.
• The wiring harness and connectors may be in poor condition.
• The ignition switch may be defective.
• The starter solenoid may be defective.

Follow the instructions below to solve the DTC P0615 OBD2:

• Consult the TBS (Technical Service Bulletins) to find useful information regarding the code.
• Check the battery charge level. If it is not at the proper level, take the necessary measures.
• Check the circuit for a blown fuse. If necessary, replace it.
• Verify that the starter relay circuit wires and connectors are not damaged or causing an open circuit. If you find some defects, make adjustments accordingly.
• Use a DVOM (Digital Volt-Ohm Meter) and perform functional tests on the components of the starter relay circuit. If the values obtained are different from the ranges specified by the manufacturer, make the necessary adjustments.
