Nissan Juke Service and Repair Manual : S terminal circuit
Description
The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START position while the selector lever is in the P or N position for CVT models or the clutch pedal is depressed for M/T models.
Diagnosis Procedure
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following
procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1.CHECK “S” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector.
3. Shift selector lever to “P” or “N” position. (CVT models) Keep depressing clutch pedal fully. (M/T models) 4. Check voltage between starter motor harness connector and ground.
Is the inspection result normal? YES >> “S” terminal circuit is OK. Further inspection is necessary. Refer to STR-14, "Work Flow".
NO >> GO TO 2.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector.
2. Check continuity between starter motor harness connector and IPDM E/R harness connector.
Is the inspection result normal? YES >> Further inspection is necessary. Refer to STR-14, "Work Flow".
NO >> Repair the harness.

DTC Logic
DTC DETECTION LOGIC
The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage c ...
