P0616 2018 Honda CR-V Code - Starter Cut Relay Diagnosis Circuit Low Voltage

Quick Answer

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. Common causes include Faulty Starter Cut Relay 2 (Built into the Relay Circuit Board), Starter Cut Relay 2 harness is open or shorted, Starter Cut Relay 2 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0616 2018 Honda CR-V 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) is a specified voltage for a set time when the starter is OFF (STS OFF), the PCM detects an ON malfunction of starter cut relay 2 and stores a Diagnostic Trouble Code (DTC).
