U151E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE 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 ignition switch off.
(2) Connect Techstream to the DLC3.
(3) Turn the ignition switch to the ON position 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's instruction book).
NOTE: When simulating symptoms with 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 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.
2. DTC CLEAR
(a) When using Techstream: Clearing the DTCs.
(1) Connect Techstream to the DLC3.
(2) Turn the ignition switch to the ON position and turn the Techstream main switch on.
(3) 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's instruction book for operating instructions.)

(b) When not using Techstream: Clearing the DTCs.
(1) Disconnect the battery terminal or remove the EFI and ETCS fuses from the engine room J/B for 60 seconds or more. However, if you disconnect the battery terminal, perform do the "INITIALIZE" procedure.
