Engine Controls Self-Diagnostics - Introduction (Exc. G20 & Q45): Overview Nissan Quest II

Note. For information on I30, refer to Maxima unless otherwise noted. For information on QX4, refer to Pathfinder unless otherwise noted.

Note. Electronic Concentrated Control System (ECCS) control module is referred to as Engine Control Module (ECM) or Powertrain Control Module (PCM).

If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. Using scan tool, review and record all DTC and freeze-frame information available. If no DTCs are present after entering self-diagnostics, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).

DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION (SENTRA)

Description

System Readiness Test (SRT) codes indicate whether self-diagnostic tests for non-continuously monitored components have been completed or are incomplete. Inspection/Maintenance (I/M) tests of the On-Board Diagnostic II (OBD-II) type emission systems may become the legal requirements in some states/areas. All SRT codes must be set, or complete, prior to performing an I/M test. See SETTING SRT CODES procedure.

If diagnostic information is erased or battery is disconnected for a prolonged period of time, vehicle must be driven in the manner prescribed to set all SRT codes. (Схема №1) SRT codes are set after component self-diagnosis has been performed one or more times. SRT codes are set whether component diagnosis is good or bad, and whether or not diagnosis is performed in consecutive trips.
