找到官方文档了。TABLE 9.0.1B: OBD Test Standards 是大家都感兴趣的。 http://www.google.ca/url?sa=t&rct=j&...3Taq0jkvwSY0NA |

对于1998 – 2000 OBD enabled light vehicle 有以下之一即失败。 Vehicle OBD computer is unable to communicate with OBD emissions test unit. 3 or more supported readiness monitors not set to “Ready”. MIL is commanded “ON” with DTC(s). For a vehicle submitted for re-testing after an initial fail and repairs, the monitor(s) that were associated with initial failure must be set to “Ready”. 对于2001 & later OBD enabled light vehicle 有以下之一即失败。 Vehicle OBD computer is unable to communicate with OBD emissions test unit. 2 or more supported readiness monitors not set to “Ready”. MIL is commanded “ON” with DTC(s). For a vehicle submitted for re-testing after an initial fail and repairs, the monitor(s) that were associated with initial failure must be set to “Ready”. |

测试步骤如下: Connect test unit to vehicle DLC. Download the vehicle data and Readiness Status to test unit. Download the vehicle MIL Command Status to test unit. Download the vehicle DTC list to test unit. Disconnect test unit from vehicle DLC. Test unit will determine compliance with OBD test standards prescribed in TABLE 9.0.1B. |

肯定能。这样会导致 at least 1 supported readiness monitors not set to “Ready”. 如果2001 or later的话,2个或以上就失败。 政府建议车主get vehicle ready for OBD II test。但如果这样做的话,灭掉的灯又会亮起来。 Step 1: Make sure the vehicle has been parked for eight hours without a start. Step 2: Start the engine and let it idle in Drive for two-and-a-half minutes with the Air Conditioning (A/C) and rear defroster on. Step 3: Turn the A/C and rear defroster o. Drive the vehicle for 10 minutes at highway speeds. Step 4: Drive the vehicle for 20 minutes in stop- and-go trac. Step 5: Your drive cycle is complete. You can now go in for your test. |

I just did my old car month ago, i cleared the code with OBDII reader and drove to the test station and failed. The guy said it is not ready for test and asked me did i just reset the code. He said it need 50 miles to clear. After 2 days running, no code came back the redo the test and pass. But this is in US, CA is most critical place for enveiromental check

1.删code后,monitors没有ready,机器不会让你过。需要若干drive cycle和一定时间决定。 2.属于ECU temper,道理上是非法的,根本就可以不跟你测,自己改回来再说。 你这tune做得太烂,好的可以将ECU中相关的code去掉(也就是去掉部分程序或code码表,永远也不会set code/light),monitor status will be always ready. 说老实话新的机器远比就机器容易作假。旧机器通过一些尾气循环的手段/或者其他车辆可以作假。新机器只需要一台模拟OBD II电脑即可。只是说对检测shop而言完全没有必要,你过不了可以挣你450大洋有条件通过,何乐不为。 |
