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 (Park) or N (Neutral) position.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to STR, "Wiring Diagram - With Intelligent Key System" or STR, "Wiring Diagram - Without Intelligent Key System".
CAUTION: Perform diagnosis under the condition that engine cannot start by the following procedure.
1.CHECK "S" CONNECTOR CIRCUIT

Is the inspection result normal?
YES >> "S" circuit is OK. Further inspection is necessary. Refer to STR, "Work Flow (With GR8-1200 NI)" or STR, "Work Flow (Without GR8-1200 NI)".
NO >> GO TO 2.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)


Is the inspection result normal?
YES >> Further inspection is necessary. Refer to STR, "Work Flow (With GR8-1200 NI)" or STR, "Work Flow (Without GR8-1200 NI)".
NO >> Repair or replace the harness or connectors.

Inspection
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware
after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a
collision be replaced
unless the collision was minor and the belts show no dam ...
S Terminal circuit
Description
The output voltage of the generator is controlled by the IC regulator at
terminal "S" detecting the input voltage
from battery.
The "S" terminal circuit detects the battery voltage to adjust the generator
output voltage with the IC voltage
regulator.
