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.

CAUTION:

A malfunction in yaw rate/side/decel G sensor system may be detected when the vehicle sharply turns during a spin turn, acceleration turn or drift driving while VDC function is OFF (VDC OFF indicator lamp is in ON status). This is not a malfunction if the status returns to normal after engine is started again. In that case, erase self-diagnosis result memory using CONSULT.
When the engine is in running status and the vehicle is on a turntable at the entrance of parking lot or on a moving unit, VDC warning lamp may turn ON and "ABS" self-diagnosis may display "YAW RATE SENSOR". In this case, yaw rate sensor is not malfunctioning. The status returns to normal when the vehicle is left from the turntable or moving unit and the engine is started again. In that case, erase self-diagnosis result memory using CONSULT.

CHECK YAW RATE/SIDE/DECEL G SENSOR POWER SUPPLY

Turn the ignition switch OFF.
Disconnect yaw rate/side/decel G sensor harness connector.

Check the voltage between yaw rate/side/decel G sensor harness connector and ground.

CHECK YAW RATE/SIDE/DECEL G SENSOR POWER SUPPLY CIRCUIT

Turn the ignition switch OFF.
Check fuse 50 (10A).
Disconnect IPDM E/R harness connector.

Check the continuity between yaw rate/side/decel G sensor harness connector and IPDM E/R harness connector.

Yaw rate/side/decel G sensor		IPDM E/R		Continuity
Connector	Terminal	Connector	Terminal	Continuity
M108	3	E119	15	Yes

Check the continuity between yaw rate/side/decel G sensor harness connector and ground.

Yaw rate/side/decel G sensor		--	Continuity
Connector	Terminal
M108	3	Ground	No

Is the inspection result normal?

YES

Perform trouble diagnosis for ignition power supply.

Repair / replace harness, connector, or fuse.

CHECK YAW RATE/SIDE/DECEL G SENSOR GROUND CIRCUIT

Turn the ignition switch OFF.

Check the continuity between yaw rate/side/decel G sensor harness connector and ground.

Yaw rate/side/decel G sensor		--	Continuity
Connector	Terminal
M108	6	Ground	Yes

Is the inspection result normal?

YES

GO TO 4.

Repair / replace harness or connector.

CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY AND GROUND CIRCUIT
Check the ABS actuator and electric unit (control unit) power supply and ground circuits. Refer to Diagnosis Procedure .

Is the inspection result normal?

YES

GO TO 5.

NO

Repair / replace harness, connector, fuse, or fusible link.

CHECK COMMUNICATION LINE

Check the continuity between yaw rate/side/decel G sensor harness connector and ABS actuator and electric unit (control unit) harness connector.

Yaw rate/side/decel G sensor		ABS actuator and electric unit (control unit)		Continuity
Connector	Terminal	Connector	Terminal
M108	4	E125	9	Yes
	5		10

Is the inspection result normal?

YES

GO TO 6.

Repair / replace harness or connector. Refer to Precaution for Harness Repair .

CHECK TERMINAL
1. Check the ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with harness connector.
2. Check the yaw rate/side/decel G sensor pin terminals for damage or loose connection with harness connector.
3. Check the IPDM E/R pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?

YES

GO TO 7.

NO

Repair / replace harness, connector, or terminal.
REPLACE YAW RATE/SIDE/DECEL G SENSOR
CONSULT.
1. Connect ABS actuator and electric unit (control unit) harness connector.
2. Replace the yaw rate/side/decel G sensor. Refer to Removal and Installation .
3. Erase "Self Diagnostic Result" mode of "ABS"
4. Turn the ignition switch OFF.
5. Turn the ignition switch ON.
  NOTE: Never start engine.
6. Perform "Self Diagnostic Result" mode of "ABS".
Is DTC "C1145" or "C1146" detected?

YES

Replace the ABS actuator and electric unit (control unit). Refer to Removal and Installation .

NO

Inspection End.
