汽车部分电器功能紊乱 -- 请大家指点!

[togeorge]

我的车(94 Grand Am)前两天自己更换turn signal flasher,换好后突然注意到以下几个故障:
1. ABS 仪表灯常亮, ABS 不工作
2. 收音机不工作(有电流声),时间显示也没有
3. 引擎不工作时,无论车门关闭与否,钥匙拔出与否,都是叮叮告警声,车内灯常亮(就是平常钥匙没拔出,打开车门时告警一样的状态),痛苦异常,不得以找到并拔掉车门告警器的连接头.

检查fuse都正常,我百思不得其解,请高手相助!
另外象这种电路问题,是不是到dealer那儿修比较好?各位可有建议,先行谢过!

买的是否原配的flasher? 或者把新装的flasher拆下来试试？

[老许,]

也许是断电后需要重新设置或者防盗锁死需要解密。

[togeorge]

拆下来也不行

估计某个接地线出了问题

他没说断过电呀！
应该是线路有虚接或接地问题。有线路图吗？贴出来看看

[togeorge]

断过电.这是电路图,

今天早上咬咬牙,把车送到dealer那儿去检测,说是要一个小时,收费$94,原以为忍痛花钱把问题解决就好了,谁想到一个小时后告诉我没查出来,问我是否继续进行下去(当然继续收费), 我赶紧叫停,面对一个没有任何检测诊断结果,却仍要全额收诊断费的单子, 我和他们干了一仗,他们这钱也太容易赚了, 我faint.见识了dealer的水平,我还是开回来再想办法吧.

[老许,]

不管你是否愿意接受，多数车行按时收费，这也许是有些车行不愿意查电路的原因之一吧。朋友说过一个极端的例子，有车跑电，查不出原因，整车大线都动了，最后花费$1400查出有一个硬币在某处导致偶尔跑电。
自己找时间慢慢查吧。

[有门!]

还有一种可能，在你动电路时可能DISCONNECT什么线，然后又接上了，这一过程造成一部分电路失电，从而改变了其应有的设置状态，造成工作状态失常。另外，GM车还有THEFT-DETERRENT功能，估计你的车也有。那东西在断电前（摘掉电池线）必须UNLOCKING，否则你的车会被锁死，不能打火，但你现在却能打火，可能就不是这个原因。

[shscott]

可以去大陆找蒋师傅。我的车几次电器问题都在他那里修。只是修得时间长一些，他要找原因。

[togeorge]

可惜我在Calgary.
整个过程是这样的:原先电器正常,只是里程表个位百位一起跳,还有速度表慢10公里/小时.我就更换了一个旧的仪表总成,然后就发现3个月不到,转向灯的flasher闪的很慢以至完全不闪了.更换了好几次,烦了,就想看看是不是仪表总成的接头有没有问题,由于是晚上路灯下,也没想到断电,当时发动机工作,车内灯打开,将仪表总成拆了一下,看看接口没问题,马上又装好,就出现上述问题了,后来断电后重新接上实验,问题依旧.
我比较同意老许,有门!兄弟的分析. 不过实在是匪夷所思,磁带机可以放音,收音机不行.谢谢各位,实在不行就这样吧,以后刹车"手动"防抱死就行了.

希望下面的信息有帮助
THEFTLOCK is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK
is activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.
1. Write down any three or four-digit number from
000 to 1999 and keep it in a safe place separate from
the vehicle.
2. Turn the ignition to ACC or ON.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until --- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MIN and 000 will appear on the display.
6. Press MIN again to make the last two digits agree
with your code.
7. Press HR to make the first one or two digits agree
with your code.
8. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.
9. Press AM-FM and this time the display will show
SEC to let you know that your radio is secure.
Note that with the ignition off, the THEFTLOCK LED
indicator will flash, indicating a secured radio.

[klatencor]

Unlocking the Theft-Deterrent Feature After
a Power Loss
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition on. LOC will appear on the display.
2. Press MIN and 000 will appear on the display.
3. Press MIN again to make the last two digits agree
with your code.
4. Press HR to make the first one or two digits agree
with your code.
5. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show SEC, indicating the radio is
now operable and secure.
If you enter the wrong code eight times, INOP will
appear on the display. You will have to wait an hour
with the ignition on before you can try again. When
you try again, you will only have three more chances
(eight tries per chance) to enter the correct code before
INOP appears.
If you lose or forget your code, contact your dealer.
Disabling the Theft-Deterrent Feature
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition to ACC or ON.
2. Turn the radio off.
3. Press the 1 and 4 buttons together. Hold them down
until SEC shows on the display.
4. Press MIN and 000 will appear on the display.
5. Press MIN again to make the last two digits agree
with your code.
6. Press HR to make the first one or two digits agree
with your code.
7. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show ---, indicating that the radio
is no longer secured.
If the code entered is incorrect, SEC will appear on the
display. The radio will remain secured until the correct
code is entered.
When battery power is removed and later applied to a
secured radio, the radio won’t turn on and LOC will
appear on the display.
To unlock a secured radio, see “Unlocking the
Theft-Deterrent Feature After a Power Loss” earlier
in this section.

TO：togeorge

我的车也是GRAND AM， 以前发生过类似的情况，雨刷一动收音机有电流声，中央锁也在行车时自己开过，后来由于换了一个发电机，收音机就不再响了。我换发电机时修车师傅说电压要是低的话，第一个亮的是ABS。

对了，有时我也觉得速度表偏低，正常行车总是比别人慢些，搞不懂是别人超速还是我慢。

我在大多，有空可以交流一下，旧车真闹心。

[togeorge]

谢谢moto人,我一定会试试.
TO: ansc,我的现在还有一个故障就是起步挂档时,中央锁不再自动锁上了.通用,福特的就是这样,听说Chrysler的好一点,车主抱怨的倒不见多.以前想买Spirit/Acclaim,老婆嫌方头方脸是老头开的,一急就错买了这个.不过发动机还蛮好.

断电后锁也需要重新设定的
我每天给你贴怎么设定。

Power Door Locks
With the power door locks, you can unlock or lock all
of the doors of your vehicle from the driver or front
passenger door lock switch.
Push the top of the switch to unlock all of the doors.
Push the bottom of the switch to lock all the doors.
Automatic Door Locks
Just close your doors and turn on the ignition. All of
the doors will lock when you move your shift lever out
of PARK (P) to REVERSE (R) for an automatic
transaxle. All of the doors will lock when the vehicle
speed is greater than 5 mph (8 km/h) for a manual
transaxle. If someone needs to get out while the vehicle
is running, have that person use the door lock. When the
door is closed again, it will lock automatically when the
vehicle reaches about 5 mph (8 km/h). All doors will
automatically unlock when the shift lever is moved to
PARK (P) and when the key is turned to OFF.
Programmable Automatic Door Locks
Programmable Automatic Door Locks is a standard feature
intended to provide enhanced security and convenience by
automatically locking and unlocking the doors.
One of four operating modes may be selected and
programmed by the driver for an automatic transaxle:
Mode 1: All doors automatically lock when the
transaxle is shifted out of PARK (P). The doors will
remain locked unless manually unlocked or the lock
button is pressed. All doors will unlock when the
transaxle is shifted into PARK (P) and the key is
turned to OFF.
Mode 2: This mode is only available with the remote
keyless entry transmitter. All doors automatically
lock when the transaxle is shifted out of PARK (P).
Automatic driver’s door only unlock when the
transaxle is shifted into PARK(P) and the key is
turned to OFF.
Mode 3: All doors automatically lock when the
transaxle is shifted out of PARK (P). No automatic
door unlock.
Mode 4: No automatic door lock or unlock.

[klatencor]

One of the four operating modes may be selected and
programmed by the driver for a manual transaxle:
Mode 1: All doors automatically lock when the
vehicle speed is greater than 5 mph (8 km/h). The
doors will remain locked unless manually unlocked
or the lock button is pressed. All doors will unlock
when the transaxle is shifted into REVERSE (R)
and the key is turned to OFF.
Mode 2: This mode is only available with the remote
keyless entry transmitter. All doors automatically
lock when the vehicle speed is greater than 5 mph
(8 km/h). Automatic driver’s door only unlock when
the transaxle is shifted into REVERSE (R) and the
key is turned to OFF.
Mode 3: All doors automatically lock when the
vehicle speed is greater than 5 mph (8 km/h).
No automatic door unlock.
Mode 4: No automatic door lock or unlock.
The Programmable Automatic Door Locks will be in
operating mode 1 when the vehicle is shipped from
the factory.
Disconnecting the vehicle battery for up to one year will
not change the programmed mode of the Programmable
Automatic Door Locks.
The operating mode of the Programmable Automatic
Door Locks will be changed when the driver performs
the following sequence with the doors closed and the
vehicle’s ignition key to ON.
To change the mode:
1. Press and hold LOCK on the power door lock
switch for 10 seconds. Release the switch when you
hear the chime.
2. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is in.
You can change the mode by pressing and holding
LOCK on the power door lock switch (two chimes
for mode 2, three chimes for mode 3 and four chimes
for mode 4).
3. Repeat Step 1 until you hear the number of chimes
that matches the mode you want.
The mode you selected is now set.

我的车与你的一样，94 GRAND AM 3.1L ，几个月前发动机坏了，自己换的，现也ABS灯亮，报警，内灯亮。现CD的进线我改装后可工作，因CD或收音机须两根12V进线，红色和黄色，但有一根直接从电源进的没电，一根从IGNITION，我把两根都接到IGNITION，可工作，无记忆，每次起动后须重新设定台。所以，我不认为是防盗系统方面的问题。
