 DTC CONFIRMATION PROCEDURE
 1.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.
 2.CHECK A/F SENSOR FUNCTION
- Start engine and warm it up to normal operating temperature.
- Select “A/F SEN1 (B1)” or “A/F SEN1 (B2)” in “DATA MONITOR” mode with CONSULT-III.
- Check “A/F SEN1 (B1)” or “A/F SEN1 (B2)” indication.
Is the indication constantly approx. 5V?
YES >>Go to Diagnosis Procedure (GT-R certified NISSAN dealer). NO >>GO TO 3.
 3.PERFORM DTC CONFIRMATION PROCEDURE
- Turn ignition switch OFF and wait at least 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF, wait at least 10 seconds and then restart engine.
- Drive and accelerate vehicle to more than 40 km/h (25 MPH) within 20 seconds after restarting engine.
■ CAUTION ■ Always drive 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.
Is 1st trip DTC is detected?
YES >>Go to Diagnosis Procedure (GT-R certified NISSAN dealer). NO >>INSPECTION END
