Code P1652 Nissan Description

The Engine Control Module (ECM) controls ON/OFF state of the starter relay, according to the engine and vehicle condition. The ECM transmits a control signal to the Intelligent Power Distribution Module (IPDM) Engine Room (E/R) by CAN communication. Under normal conditions, the ECM controls and maintains the starter relay in OFF state during the following condition: The engine is running, the selector lever is D position. (CVT models), and the clutch pedal is fully released. (M/T models). When detecting a decrease in engine speed due to rapid deceleration or heavy load conditions, ECM controls and reactivates the starter relay. The IPDM E/R detects a control state of the starter relay and starter control relay and transmits a feedback signal to ECM via CAN communication. The Diagnostic Trouble Code (DTC) will set when the ECM detects a malfunction in the starter motor drive circuit of the IPDM E/R.
