2000 Celica electrical problems

I have a 2000 Celica. My door locks will not work from the remote or from the center console lock/unlock button, my fuel gauge shows empty, my automatic head lights do not come on automatically, and My dome light will not come on with the doors. I have checked the plugs to the ecu all look secure. Does this sound like the body ECU has gone bad??

You may have a bad grounding wire from the negative battery terminal to the body. This would cause all kinds of electrtical problems.

Key buttons will not operate locking system,i have changed battery but still no good.use master key,gets me into the car but alarm goes off and also when i attempt to drive it.

I have the same problem kinda. Lost my master key and sent my ecu off with a home made 2 button key to program immobiliser. This key works to start the engin and drive but I cannot get the key to program with the alarm and locking system. You can try the following steps as may work for you.

I can get my car into programming mode after step 1 but step 2 does not work for me. The locks do not go off at all, not once or twice. Battery in remote key is fine as LCD lights red.

Can anyone help please?

2000 Celica GT - I can get into the programming mode just fine, but I have tried to program THREE separate remotes and none of them will program. They are used, so I am "rewriting" them, but they never...

I saw this on one of the toyota forums;
1) Getting a Replacement Remote

Look on ebay or google, make sure the remote has the following FCC-ID: bab237131-056

2) Installing the remote (credit to iPal)

1 open door, take key out...

2 insert and remove key from ignition 2 times

3 close and open driver's door 2 times

4 insert and remove key from ignition

5 close and open driver's door 2 times

6 insert key into ignition

7 close door

8 turn ignition from 'lock' to 'on' and back to 'lock'

if you do step #8

*1 time it's for add mode

*2 times for rewrite mode

*3 times for confirmation mode

*4 times for prohibition mode

9 remove key

10 then door lock will cycle 'lock' and 'unlock' a number of times
corresponding to your key cycles in step #8

11 press lock and unlock button together for 1 ~ 1.5 sec then release

12 then within 3 sec press lock button for 1 sec then release

13 if you did correctly door lock will cycle once...

if wrong, twice... then do it over...

The remote unlock for my 2000 Jetta no longer works on the driver door. It unlocks the other doors and pops the trunk. Is it the lock? I have to use the key to unlock the drivers door.

First thing to do is check for a burned out fuse. If that is not the problem, then check for a defective relay. A lot of newer cars, including VW's, use relays for several things, including the power door locks. If you have the owners manual, the location of the fuse and relay box should be in there. If not, try to find a repair manual, or an on-line repair manual such as All-data or Mitchell on-line. If the problem is not the relay, then the problem is either going to be in the control module that recieves the signal from your remote and sends the command to lock or unlock your doors, an open in the wiring, or both lock solenoids went bad on you. As a reminder, always use caution when working on electrical systems, ans accidently shorting out something could cause a lot of other problems.
