Code P0615 Honda Description

The starter control system prevents the starter from accidentally activating when the shift position is not in the P or N position/mode, or when the engine is running. If the vehicle is turned mistakenly while the shift position is not in P or N or while the engine is running, the Powertrain Control Module (PCM) will stop power to the starter cut relays. However, cranking to return from an auto idle stop does not correspond to this. In this system, two starter cut relays are connected in series (starter cut relay 1, starter cut relay 2) to prevent the starter from running continuously due to a starter cut relay malfunction. Also, a diagnosis line (START DIAG) is connected to monitor the voltage between the starter cut relay 1 and starter cut relay 2. Based on the diagnosis line signals, the PCM detects an OPEN malfunction of the diagnosis line, an ON malfunction of starter cut relay 1, and an ON malfunction of starter cut relay 2. The PCM also equipped with return signal circuits of starter cut relay 1 and starter cut relay 2 to detect an OFF malfunction. If the voltage of the diagnosis line (START DIAG) input does not exceed the upper and lower limits for a specified duration when the starter is ON (STS ON), the PCM detects an OPEN malfunction of the diagnosis line and stores a Diagnostic Trouble Code (DTC).
