DTC Diagnosis Procedure

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

The output voltage of the generator is controlled by the IC regulator at terminal "3" (S) detecting the input voltage. Terminal "3" circuit detects the battery voltage to adjust the generator output voltage with the IC regulator.

CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION
Check to see if connector E205 terminal 3 is clean and tight.

Is the inspection result normal?

YES

GO TO 2.

NO

Repair terminal "3" connection. Confirm repair by performing system test using the DSS-5000P NI. Refer to the applicable Instruction Manual for proper testing procedures.

CHECK VOLTAGE REGULATOR CIRCUIT

Check voltage between generator harness connector E205 terminal 3 and ground.

(+)		(-)	Voltage
Connector	Terminal
E205	3	Ground	Battery Voltage

Is the inspection result normal?

YES

Refer to Work Flow (With DSS-5000P NI) or Work Flow (Without DSS-5000P NI) .

Check harness for open between generator and fuse.
