Its official, car is haunted. Getting a video.

Scrached that, was only opening and closing because the drivers side was open.

Well, the doors lock when I start the car. That is it though. I can't lock or unlock all the doors from anywhere.

Heres the video for shits and giggles.

Here is a video of just the two doors being hooked up but from the inside.

I just plugged in a new clcu and still doesn't work. Going to try disconnecting.

Ah right makes sense. I gather this is the same logic behind a "reset" of the system which I've read of:

1) disconnect battery
2) unlock all doors/trunk/gas cap
3) reconnect battery

Assuming all this doesn't work and the actuator is indeed bad, can this be confirmed by jumping the wires on the actuator connector to simulate the lock/unlock? If it's only the driver's door actuator that's bad, jumping the connector wires should unlock/lock everything else properly right?

[e30partsguy]

CL system will not work if actuators are out of sync (passenger in lock position and trunk in unlock position), unplugging the trunk and gas door actuators, now we only have driver and passenger actuators, if passenger door still won't unlock, the actuator is bad

[evilnickwong]

Try unplugging the actuators in the trunk and gas tank then put key in driver side door, turn key to lock then unlock.

What does unplugging the trunk and gas filler actuators accomplish?

Trying to understand as my CL system isn't working either.

:DGood luck!

Crap, well thanks for the help I might PM you if I got any questions. Now to go on a mission for ECU and actuators...

[rav320uk]

Change the ECU first, then go to the actuators

[Wardie]

Nothing still :/

Must be the unit or relay?

Im concerned it might be something with the passenger door, you can't unlock it manually you have to go into the door and rip out the actuator.

[rav320uk]

Fingers crossed this time:D

Look at the pic below, it should make more sense.
BUT, do you know what wire you cut from where????
If so, join them back together and start again!!!!!!!!!!

Look at this pic, it's simple.

Yeah I know which from where, also silly I was confused for a second by the drawing but I forget you're from England :P

So, basically just join the thicker wire with the thin wire.. ALRIGHT gonna go clean up my mistakes and try this again.

[rav320uk]

Kind of...

So wire No.2 & No.3 are car side

No.4 is relay

No.1 Goes to a-pillar

Then there the thicker wire which runs from a-pillar to unit.

Seeing I cut one to many wires, will the final connection be a three way? or.. do I leave a wire out? Alittle confuzzled right now.


EDITED: Added awesome paint picture.



This is currently how the wiring looks.

LOL, i just posted a pic too.
looks like you cut the wrong wires.
You need to cut the "Unit to Plug wire and connect it to 1/2 on the Car side.
