马自达3行车电脑的解锁方法

新锐车网搜集整理的五种马自达3行车电脑解锁方法写出来，供大家参考，希望能对还在摸索的同学有所帮助。

日规版Mazda3从推出至今已经陆续出过三代，按尾灯的颜色可以明显区别开来，分为：
第一代：彩色普通尾灯、红灯罩
第二代：彩色普通尾灯、黑灯罩
第三代：白色LED尾灯、黑灯罩

其中第一代完全不能解锁，第二代大部分可以解锁，第三代全部可以解锁。第二代和第三代换过音响的车，全都不能解锁。

解锁成功与否和音响的批次相关性很高，新加坡也出现过1月出厂的车可以解锁，3月出厂的车反而解不开的事情。我们猜想是因为Trip Computer的良率、准确性和稳定性不高，马自达不愿意为此承担保修责任，而选择了向Mazda3的经销商和用户隐瞒的做法。在马自达的高端车型上，Trip Computer就作为功能之一，大张旗鼓地进行宣传，那是因为高端车型用了绝对过关的Trip Computer。我的朋友中有人因为加油而造成Trip Computer崩溃，不再显示数字，而只有一个“F”，结果老老实实回马自达公司去自首，让人家给复位。

以下为完整的解锁方法，其中第一种适用于大部分情况。

Method 1
1) Hold FM 1/2 and CD button with key at OFF position
2) Turn key to ACC and you will see HELLO followed by DIS ON

5) Press clock to go back to clock display and set to trip display

Method 2
1) Get in, close door.
2) Insert key - DON'T TURN.
3) Hold down the 'FM1/2' or 'AM/FM' button together with the CD button. Keep them held down.
4) Turn key to ACC. Display reads 'Hello' immediately followed by 'DIS ON' (Driver Information System - On).
You might also find success turning the engine on at this stage.
5) Press the 'SET' key for at least 5 seconds. You should hear a beep.
6) Turn engine off, then back to ACC (or turn engine back on)
7) Press 'SET' again to cycle through the functions. Press 'CLOCK' to return to the clock. Press 'SET' again for the fuel trip computer.
To reset the meter, just hold down the 'SET' button on whichever mode you want reset.

Method 3
1) Before starting the engine, keep the 'CD' and 'FM1/2' buttons pressed.
2) Start the engine.
3) After 5 seconds, you should see 'DIS ON'
4) Stop the engine.
5) Start the engine again.
6) Now, you should have your fuel computer activated.

Method 4

2) Start the car
3) Turn on the stereo - while the stereo is on, press the 'FM1/2' button at the same time as the 'CD' button for about 5 seconds.
4) You should then get a message saying 'DIS ON'
5) At that point, turn off the car and turn it back on to see if the trip computer has actually been activated.

Method 5
Press the 'SET' button on the stereo and the 'VOLUME +' button on the steering wheel with the ignition in the 'ON' position.
(It was found that pressing the 'AM' button and 'MEDIA' buttons with the ignition on it displays 'DIS OFF', but this did not switch the trip meter off).
