车载诊断系统——OBD II
您的车辆装备有先进的OBD II车载诊断系统。
该系统监测排放、发动机和自动变速箱控制系统的工作情况。这些系统工作正常的时候，您的车辆有出色的动力表现和燃油经济性，发动机排放也在**规定的范围内。如果这些系统的任何一个部分需要维修保养，OBD II都会点亮MIL（故障指示灯）灯，同时将诊断代码和其它有关信息存储起来，以便能为维修技术人员提供帮助。虽然在一般情况下，车辆可以继续驾而无需牵引，但是我们还是建议您尽快找授权销售商做检查。
注意！
lMIL灯点亮情况下，继续驾驶可能会使排放控制系统受到进一步的损害，燃料经济性和驾驶性能也会受到影响。在做任何排放检测之前，务必对车辆进行维修保养。
l如果发动机工作时候，MIL闪烁，很快将会发生催化转化器严重损坏和动力丧失。这时候需要立即送修。
排放检测和维修程序
某些地区，法律要求车辆必须通过排放控制系统的检测。未能通过者不准进行车辆登记。对于那些需要进行检测和维护的州，这项检测要求确认MIL指示灯功能正常，发动机启动后，该指示灯不亮，OBD II系统准备好受测。正常情况下，OBD II 系统都是准备好的。如果车辆刚做过保养，近期发生蓄电池没电或者刚换过电池，那么，OBD II系统有可能没有准备好受测。如果 OBD II系统没有为受测做好准备，则车辆有可能通不过该项测试。在去测试站之前，你可以使用点火开关钥匙试验对车辆进行一次简单的测试。要确定该车OBD II系统已准备好受测，你必须按以下步骤进行：
1，把点火开关钥匙插入。
2，把钥匙转向 ON 位置，但不发动引擎。
3，如果你发动了引擎，则必须重新来一遍。
4，只要钥匙转向 ON 位置，就能看见作为正常灯检查（系统自检）的一部分的MIL指示灯的符号。
5，以后大约15秒后，下面两件事情之一将发生：
A，MIL灯闪动大约10秒钟，然后完全点亮，直到把钥匙转到OFF位置，或者发动引擎。这个表示OBD II 系统还没有准备好，你不应该去检测维修站。
B，MIL灯不闪动，保持完全点亮状态，直到将钥匙转到OFF位置，或者发动引擎。这个表示OBD II系统已经准备好受测，你可以去测试维修站了。
如果 OBD II 系统没有准备好受测，应该马上去授权经销商或修理厂进行维修。如果这辆车刚做过保养，或者电池没电，或者刚刚换过电池，那么你可以如常驾驶你的爱车，而不需要做任何事情，等待OBD II系统更新（怎么更新，谁来更新？是系统自动更新吗？）。重复上述试验步骤，结果可能就会显示已做好受测准备了。
不管OBD II 系统是否做好受测准备，如果 MIL在正常行驶时点亮了，在送检测站之前，都应该先进行维修保养。MIL在引擎发动时点亮，检测站根据这个就可能判您的车辆不合格。

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard Diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transaxle control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emissions well within current government regulations.
If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light (MIL).” It will also store diagnostic codes and other information to assist your service technician in making repairs. Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause further damage to the emissions control system. It could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions tests can be performed.
•If the MIL is flashing while the engine is running, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an inspection of this vehicle’s emissions control system. Failure to pass could prevent vehicle registration.
For states that require an Inspection and Maintenance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on when the engine is running, and that the OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II system may not be ready if the vehicle was recently serviced, recently had a dead battery, or a battery replacement.
If the OBD II system should be determined not ready for the I/M test, the vehicle may fail the test.
This vehicle has a simple ignition key-actuated test, which you can use prior to going to the test station. To check if this vehicle’s OBD II system is ready, you must do the following:
1. Insert the ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank or start the engine.
3. If you crank or start the engine, you will have to start this test over.
4. As soon as you turn the ignition key to the ON position, you will see the MIL symbol come on as part of a normal bulb check.
5. Approximately 15 seconds later, one of two things will happen:
a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the ignition key or start the engine. This means that the vehicle’s OBD II system is not ready and you should not proceed to the I/M station.
b. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition key or start the engine. This means that the vehicle’s OBD II system is ready, and you can proceed to the I/M station.
If the OBD II system is not ready, you should see an authorized dealer or repair facility. If this vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive the vehicle as you normally would in order for the OBD II system to update. A recheck with the above test routine may then indicate that the system is now ready.
Regardless of whether the vehicle’s OBD II system is ready or not ready, if the MIL is illuminated during normal vehicle operation, you should have the vehicle serviced before going to the I/M station. The I/M station can fail the vehicle because the MIL is on with the engine running.
