DTC CHECK / CLEAR

從標準模式切換到其它診斷模式後，所有保留在標準模式下的DTC資訊(含凍結的資料)都會被清除，建議您在離開標準模式前，先將此模式下有關的DTC資訊記錄起來。

*DTC: Diagnostic Trouble Code 故障診斷代碼的簡稱

提示:

只要是存放在ECM(行車電腦)中的DTC代碼，都能透過Techstream讀取，Techstream支援顯示「即時」、「已發生」與「持續/永久」三種狀態分類的DTC代碼.
行駛過程中儀表板所顯示的故障燈號，會被分類到「即時」與「持續/永久」兩種狀態.
當行駛過程中，行車電腦在一秒內持續收到同樣的DTC代碼，接下來收到的這個代碼就會分類在「已發生」的分類.
「即時」與「已發生」的DTC代碼，可以透過「Techstream」或「斷開小電瓶的負極電纜連接」清除；請注意，這兩種方式是不能清除「持續/永久」狀態的DTC代碼.
要清除「持續/永久」狀態的DTC代碼，必須先透過「Techstream」或「斷開小電瓶的負極電纜連接」清除「即時」狀態DTC代碼。接下來參考DTC代碼、分析系統運作的行為，依照對應的對策處置，讓系統判定為正常以清除「持續/永久」狀態的DTC代碼.

「已發生」的DTC代碼	狀態	故障被觸發(第1次)
「已發生」的DTC代碼	解除方式	方法1:讓系統判定已恢復正常。方法2:透過Techstream清除此代碼。方法3:斷開小電瓶的負極電纜連接。
「即時」的DTC代碼	狀態	故障被觸發(第2次)
「即時」的DTC代碼	解除方式	方法1:接下來連續40次循環無故障被觸發，就會解除。方法2:透過Techstream清除此代碼。方法3:斷開小電瓶的負極電纜連接。
「持續/永久」的DTC代碼	狀態	故障被觸發(第2次)
「持續/永久」的DTC代碼	解除方式	方法1:連續3次啟動電門，行車電腦判定一切正常後，即會自行消除。方法2:先透過「Techstream法」或「斷開小電瓶的負極電纜連接」清除後，行車電腦判定一切正常即會自行消除(此流程不適用於「點火系統」或「供油系統」相關的DTC代碼) 方法3:先透過「Techstream法」或「斷開小電瓶的負極電纜連接」清除後，行車電腦沒有收到任何DTC代碼即會自行消除(此流程不適用於「點火系統」或「供油系統」相關的DTC代碼)
MIL故障燈	ON	MAL故障被觸發(第2次)
MIL故障燈	OFF	方法1:連續3次啟動電門，行車電腦判定一切正常後，即會自行消除方法2:透過Techstream清除此代碼方法3:斷開小電瓶的負極電纜連接

備註:

1.檢查DTC：

(a) 開啟Techstream並連接OBD。

(b) 發動車輛 (IG).

(d) 檢查 DTC(s) 與 freeze frame 資料並記錄。

(e)點DTC可以看到詳細訊息。

2. 清除 DTC 方法一 (Pending and Current DTC)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(e) Clear the DTCs.

3. 清除 DTC 方法二 (Pending and Current DTC without using Techstream)

(a) Perform either of the following operations:

(1) Disconnect the cable from the negative (-) battery terminal for more than 1 minute.

(2) Remove the EFI MAIN and ETCS fuses from the engine room relay block located inside the engine compartment for more than 1 minute.

4. 清除 PERMANENT DTC 方法三

HINT:

Even if the following procedure is not performed, permanent DTCs are cleared by obtaining a normal judgment during 3 consecutive driving cycles.

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(e) Check if permanent DTCs are stored.

HINT:

If permanent DTCs are not output, it is not necessary to continue this procedure.

(f) Clear DTCs.

(g) Perform the respective confirmation driving patterns in order to obtain a normal judgment for the output DTCs.

HINT:

Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs.
For the confirmation driving pattern, refer to the procedures for the relevant DTC .

(h) Perform the universal trip.

HINT:

The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle.

Put the engine in inspection mode .
Idle the engine for 30 seconds or more.
Drive the vehicle at 25 mph (40 km/h) or more for a total of 5 minutes or more.HINT:It is possible to complete the drive pattern even if the vehicle decelerates to less than 25 mph (40 km/h) during the driving cycle provided that the vehicle is driven at 25 mph (40 km/h) or more for a total of 5 minutes.
Allow 10 minutes or more to elapse from the time the engine is started.

(i) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

(j) Check that the permanent DTCs have been cleared.

HINT:

The permanent DTCs are cleared when the universal trip is completed.
