Nissan Juke Service and Repair Manual : P1651 starter motor relay
Description
ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. Models with no Intelligent Key System transmit a control signal directly to IPDM E/R. On the other hand, models with the Intelligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN communication.
Under normal conditions, ECM controls and maintains the starter relay in OFF state during engine running or “D” position.
When detecting a decrease in engine speed due to rapid deceleration or heavy load condition, ECM controls and reactivates the starter relay.
IPDM E/R detects a control state of starter relay and starter control relay and transmits a feedback signal to ECM via CAN communication.

NO >> Perform trouble diagnosis for DTC indicated.
4.CHECK CRANKING REQUEST SIGNAL CIRCUIT-I
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Disconnect IPDM E/R harness connector.
4. Check the continuity between ECM harness connector and IPDM E/R harness connector.
5. Also check harness for short to ground to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK CRANKING REQUEST SIGNAL CIRCUIT-II
1. Disconnect BCM harness connector.
2. Check the continuity between ECM harness connector and BCM harness connector.
3. Also check harness for short to ground to power.
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair or replace error-detected parts.
