Remote keyless entry module


First off we need to know if it is a factory or aftermarket alarm. Plus, whether you have a fob or not won't make the alarm malfunction. If I were to venture a guess you have an aftermarket alarm that has gone around the bend. But if it is a factory unit then defective door switches (the ones that turn off the dome lights when the door is closed) could be the problem. Also there could be a problem with the power door locks themselves but not real likely. The body module could have issues in the security section, again not real likely. Usually problems like this are found in bad grounds, switches, intermittent power feeds, or something similar. Even if one of the door jamb switches is just loose and able to shift around could cause weird things to happen. And don't forget the switches under the hood and trunk lid. You can try each door switch by just pushing it in and out and wiggling it around with your finger to see if it has a short or bad ground. If it does the dome light will go on and off as you wiggle the plunger and that may be your problem. Good luck. Intermittent electrical problems are the hardest ones to find.

Beings as everything that stopped working is on the passenger side, I'd think some wiring got disconnected or broken.

Can you supply me with the colour code for the wiring on the alarm/central locking unit under the dash on a 2002 vw golf ? i am fitting a remote start alarm and when i remotely lock the doors i need the vw...


This is what I have for the Golf 2001:

' ITEM ' WIRE COLOR 'POL' WIRE LOCATION '
' 12V 'red '+ 'ignition harness '
' STARTER 'red/gray '+ 'ignition harness '
' IGNITION 'black '+ 'ignition harness '
' ACCESSORY 'black/red '+ 'ignition harness '
' POWER LOCK 'yellow/blue '- 'drivers door module *1 '
' POWER UNLOCK 'green/red *2 '- 'drivers door module *1 '
' LOCK MOTOR 'purple/yellow ' 'drivers door module *1 '
' UNLOCK MOTOR 'blue/yellow ' 'drivers door module *1 '
' DISARM DEFEAT 'pur/yel or blu/yel ' 'passengers door module *3 '
' PARKING LIGHTS + 'gry/red & gry/blk ' 'drivers kick panel '
' HEADLIGHTS 'yellow/red '+ 'headlight switch '
' DOOR TRIGGER 'blue/gray *4 '- 'comfort module *5 '
' DOME SUPERVISION 'blue/gray '- 'comfort module *5 '
' TRUNK/HATCH PIN 'brn/blk or brn/blu '- 'hatch light '
' HOOD PIN 'brown/red '- 'comfort module *5 '
'TRNK/HTCH RELEASE 'brown/black '- 'comfort module *5 '
' FCTRY ALARM ARM 'arms w/ lock ' ' '
' FCTRY ALRM DISARM 'disarms w/ unlock ' ' '
' TACHOMETER 'green/stripe ' 'ignition coil '
' SPEED SENSE ' ' ' '
' BRAKE WIRE 'red/black '+ 'drivers kick panel '
' HORN TRIGGER 'black/yellow '+ 'comfort module *5 '
' WIPERS 'grn/yel and green '+ 'wiper motor

*1 The drivers door module is located in the drivers door.
*2 A double pulse will unlock all doors and disarm the factory alarm.
*3 The passengers door module is located in the passengers door.
*4 This wire will read the dome light delay. The avoid the dome light delay, use the separate door trigger wires and diode isolate each one. They are brown/white and are all located in their own door at their own door module.
*5 The comfort module is the main control module located under the drivers side of the dash.

Use this diagram for the door trigger isolation: motorsport.com/images/install_notes/149.jpg

Use DIAGRAM A.


Hope this helps.

Can not lock car by key remote . toyota rav 4 53 plate


If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.

99 Sienna pwr door lock failure


Sounds electrical/relay to me if you cannot lock by pressing the lock button on the door itself. Driver and passenger acting the same AND the remote all the same result point to only one culprit.
Let me know how it goes and best of luck!

99 sienna pwr door locks not locking


Well, I went to the dealer and was told that Integration relay does run both the remote locking, physical pressing the actual lock/unlock button on the armrest and dome light and door chime. I had NONE of these functioning, despite checking/replacing fuses, trying to reprogram the key, etc.
I do not have the picture of the relay with me right now.
Please explain the problem in little bit more detail and what did you already do try to fix it and I will see what I can do.
