U241E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: DTC CHECK / CLEAR

DTC CHECK / CLEAR

1. CHECK DTC
(a) DTCs which are stored in the ECM can be displayed with Techstream.
Techstream can display pending DTCs and current DTCs. Some DTCs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending DTC.
(1) Connect Techstream to the DLC3.
(2) Turn the ignition switch ON and turn the tester 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 Transaxle System.
NOTE: When simulating a symptom with the scan tool to check for DTCs, use normal mode. For codes on the DIAGNOSTIC TROUBLE CODE CHART 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 symptom has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.
2. CLEAR DTC
(a) When using Techstream:
(1) Connect Techstream to the DLC3.
