A760E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: DTC CHECK / CLEAR

DTC CHECK / CLEAR

1. DTC CHECK (NORMAL MODE)
NOTE:
When the diagnostic system is switched from the normal mode to the check mode, all the DTCs and freeze frame data recorded in the normal mode will be erased. So before switching modes, always check the DTCs and freeze frame data, and note them down.

(a) Checking DTCs using Techstream.
(1) Turn the engine switch off.
(2) Connect the Techstream to the DLC3.
(3) Turn the engine switch on (IG) and turn the Techstream main switch ON.
(4) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(5) Use Techstream to check the DTCs and freeze frame data and note them down (For operating instructions, see the Techstream instruction book).
NOTE:
When simulating symptoms with the Techstream to check the DTCs, use the normal mode. For codes on the DTCs chart which are subject to "2 trip detection logic";

Turn the engine 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.
2. DTC CLEAR
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG) and turn the Techstream main switch ON.
(c) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Clear.
HINT:
When operating Techstream to erase the codes, the DTCs and freeze frame data will be erased. (See the Techstream instruction book for operating instructions.)
