P0615 on Nissan
Starter Relay Circuit
P0615 on Nissan vehicles indicates starter relay circuit. Au7o has documented this code across 2 Nissan models — most commonly on Frontier, Pathfinder. This code means the engine/powertrain computer detected a fault (open, short, or unexpected voltage) in the starter relay control circuit, which the module uses to energize the starter relay and crank the engine. On vehicles with computer-controlled or push-button start, this circuit is part of the path that allows the engine to be started. A fault here can cause intermittent or no-crank/no-start conditions, so it is worth diagnosing even though it does not affect a running engine. Typical repair costs on Nissan range from $150 to $900, depending on the specific model and root cause.
Common Causes of P0615
- •Faulty starter relay
- •Damaged, corroded, or loose wiring/connectors in the relay circuit
- •Open or shorted control wire to the relay
- •Corroded relay socket or fuse box terminals
- •Blown fuse in the starter control circuit
- •PCM/ECM driver fault (rare)
P0615 on Nissan by Model
Nissan Frontier(1 issue)
- Intermittent No-Start or Stall from Faulty Start/Stop Logic and ECM Software2022-2024
Owners of the new-generation Frontier have reported intermittent no-start events, extended crank, or occasional stalling tied to control-module logic, battery state sensitivity, or software calibration issues. Complaints commonly describe the truck acting like a weak battery or failing to restart normally despite the battery testing good. Nissan has issued service information and software-related fixes for some starting and drivability complaints on this platform.
Nissan Pathfinder(1 issue)
- Auto Start-Stop System Failure and No-Restart/Stall Events2022-2025
Multiple owners reported the Pathfinder shutting off at a stop with the auto start-stop system and then failing to restart promptly, sometimes displaying warning messages or requiring a manual restart attempt. Nissan issued a safety recall for certain vehicles related to the idle stop/start system because the engine may not restart after an auto stop event, creating a stall condition and increasing crash risk. Complaints often describe the issue occurring at traffic lights or in heavy traffic, with the vehicle briefly immobilized.
