DTC Confirmation Procedure
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
-
Turn ignition switch OFF and wait at least 10 seconds.
-
Turn ignition switch ON.
-
Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V at idle.
>>
GO TO 2.
CHECK A/F SENSOR FUNCTION
With CONSULT
-
Start engine and warm it up to normal operating temperature.
-
Select “A/F SEN1 (B1)” in “DATA MONITOR” mode of “ENGINE” using CONSULT.
-
Check “A/F SEN1 (B1)” indication.
With GST
Follow the procedure “With CONSULT” above.
Is the indication constantly approx. 0 V?
YES>>Proceed to DTC Diagnosis Procedure
NO>>GO TO 3.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
-
Turn ignition switch OFF, wait at least 10 seconds and then restart engine.
-
Drive and accelerate Nissan Ariya vehicle to more than 40 km/h (25 MPH) within 20 seconds after restarting engine.
CAUTION:
Always drive Nissan Ariya vehicle at a safe speed.
-
Maintain the following conditions for about 20 consecutive seconds.
ENG SPEED 1,000 - 3,200 rpm VHCL SPEED SE More than 40 km/h (25 mph) B/FUEL SCHDL 1.5 - 9.0 msec Selector lever Suitable position
NOTE:
-
Keep the accelerator pedal as steady as possible during the cruising.
-
If this procedure is not completed within 1 minute after restarting engine at step 1, return to step 1.
-
-
Check 1st trip DTC.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected?
YES>>Proceed to DTC Diagnosis Procedure.
NO-1>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO-2>>Confirmation after repair: INSPECTION END
DTC Diagnosis Procedure
CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY
-
Turn ignition switch OFF.
-
Disconnect A/F sensor 1 harness connector.
-
Turn ignition switch ON.
-
Check the voltage between A/F sensor 1 harness connector and ground.
+ − Voltage A/F sensor 1 Connector Terminal F18 4 Ground Battery voltage
Is the inspection result normal?
YES>>GO TO 3.
NO>>GO TO 2.
CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
-
Turn ignition switch OFF.
-
Disconnect IPDM E/R harness connector.
-
Check the continuity between A/F sensor 1 harness connector and IPDM E/R harness connector.
+ − Continuity A/F sensor 1 IPDM E/R Connector Terminal Connector Terminal F18 4 F35 75 Existed -
Also check harness for short to ground.
Is the inspection result normal?
YES>>Perform the trouble diagnosis for power supply circuit.
NO>>Repair or replace error-detected parts.
CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
-
Turn ignition switch OFF.
-
Disconnect ECM harness connector.
-
Check the continuity between A/F sensor 1 harness connector and ECM harness connector.
+ − Continuity A/F sensor 1 ECM Connector Terminal Connector Terminal F18 1 F72 56 Existed 2 60 -
Check the continuity between A/F sensor 1 harness connector and ground, or ECM harness connector and ground.
+ − Continuity A/F sensor 1 Connector Terminal F18 1 Ground Not existed 2 + − Continuity ECM Connector Terminal F72 56 Ground Not existed 60 -
Also check harness for short to power.
Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair or replace error-detected parts.
CHECK INTERMITTENT INCIDENT
Perform Intermittent Incident. Refer to Intermittent Incident.
Is the inspection result normal?
YES>>GO TO 5.
NO>>Repair or replace error-detected parts.
REPLACE AIR FUEL RATIO (A/F) SENSOR 1
Replace air fuel ratio (A/F) sensor 1. Refer to Exploded View.
