1. CHECK DTC
(a) DTCs which are stored in the ECM can be displayed with Techstream or a generic OBD II scan tool.
These scan tools can display pending DTCs and current DTCs. Some DTCs aren't stored if the ECM doesn't detect a malfunction during consecutive driving. However, malfunctions detected once during driving are stored as pending DTCs.
(1) Connect Techstream to the DLC3.
(2) Turn the ignition switch ON, and turn the tester main switch ON.
(3) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(4) Confirm the DTCs and freeze frame data and then write them down.
(5) Confirm the details of the DTCs Automatic Transmission System - A750F.

NOTE: When simulating a symptom with the scan tool to check the DTCs, use normal mode. For codes on DIAGNOSTIC TROUBLE CODE CHART which are subject to "2-trip detection logic", perform the following actions:

Turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.
