 DTC CONFIRMATION PROCEDURE

■ CAUTION ■
  • If CONSULT-III is not available, “Diagnosis Procedure (GT-R certified NISSAN dealer)” must be performed before starting “DTC CONFIRMATION PROCEDURE”.
  • If CONSULT-III is not available, never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause secondary malfunction.
  • Be careful of the driving speed.
