在 小肥的原廠維修手冊裡..... 機乎有問題以後. 都沒方法可以弄好的時候. 就會叫我換一顆好的ECU ....
換了 ECU 以後.. 或者做過一些東西以後... 都會叫我 reset ecu with HDS . ... 之後都會寫著...要 lean idle speed 一次. 有時候還會叫我們 learn CKP .
不過. learn idle speed . learn CKP 等等.. 或者是 clear HTC (故障碼). 都有得選擇 "without HDS" 或是 "with HDS" 兩種方法...
不過. 我就是沒有找到 "reset ecu " 有 with HDS 的方法.... 也就是說.... 一般我們以為拆電瓶的方法. 其實跟本就沒有 reset 到 ecu .
這裡. 是我隨便找的一頁.. "000000000000746.html" 裡面寫得都相當清楚.... 要做一次 learn idle 只有做過下面 5 件事的...才要 learn idle . 那就是說.. 換電瓶.跟本就不用 idle lean .. .也就是. 沒有 reset 得到 ECU 吧!!..
再來... 一句 "Reset the ECM/PCM with the HDS" .... 這句話.. 有維修手冊裡. 極常見....
不過. "Reset the ECM/PCM without the HDS" . 我就完全沒看到了....................
媽的..... 難道要 reset ECU 就一定要去買 HDS 回來自己弄嗎?
我真的哭出來了....

ECM/PCM Idle Learn Procedure
The idle learn procedure must be done so the ECM/PCM can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of these actions:
Replace the ECM/PCM.
Reset the ECM/PCM.
Update the ECM/PCM.
Replace or clean the throttle body.
When the engine or transmission is disassembled.
NOTE: Clearing the DTCs with the HDS does not require you to do the idle learn procedure.
Procedure
Make sure all electrical items (A/C, audio, lights, etc.) are off.
Reset the ECM/PCM with the HDS.
Turn the ignition switch to ON (II), and wait 2 seconds.
Start the engine. Hold the engine speed at 3,000 rpm (min −1 ) without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 90 °C (194 °F).
Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.
Verify on the HDS data list that the idle learn procedure is complete.
