DIAGNOSTIC TROUBLE CODES







1. If there is more than one malfunction, the codes will be indicated in numerical order, lowest number first.






2. The MIL flashes to indicate the same pattern as the buzzer of the EC-AT Tester when the test connector, (green, 1-pin) is grounded, When the test connector is not grounded, the indicator flashes at a constant frequency unless the malfunction recovers. However, the malfunction code is memorized in the EC-AT control unit.






3. The EC-AT control unit has a built-in fail-safe function for the throttle position sensor, the pulse generator, and the 1-2, 2-3, and 3-4 shift solenoid valves. If a malfunction occurs, the EC-AT control unit will control operation of the remaining components according to a preset fail-safe program. The vehicle may still be driven, although driving performance will be slightly affected.






4. The memory of malfunction codes is cancelled when the negative battery terminal is disconnected for approximately 5 seconds.
