DTC P1605: A/T Diagnostic Communication Line: Notes

WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Using the following diagnostic procedure assumes the presence of a current (hard) DTC or the ability to duplicate the setting of the DTC using DTC confirmation test(s), intermittent recreation procedures or a test drive under conditions stored in freeze frame data. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM. If DTC cannot be duplicated, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.

NOTE: The malfunction information related to A/T (Automatic Transaxle) is transferred through the line (circuit) from TCM (Transmission Control Module) to ECM. Therefore, be sure to erase the DTC not only in TCM (Transmission Control Module) but also ECM after the A/T related repair.
