    Thanks for your reply but your explanation is for an experienced technician with equipemtnt like ;mulit-meters etc and then probing ecery circuit and connection, all something that I have no kowledge of, nor the time or exprertise , or most important the time and inclination to do all of this. Thanks again but a copy o fthe alpine manual I can look through and get simpler explanations would be more helpful.

I dont have the manual, but its possible that your problem is just one error wiring; so, check this list to check it...

In the hopes of jogging someones memory here, I'm going to post what I have, know and think for the wiring schematic colour codes:

MAIN HARNESS:
RED - Ignition
YELLOW (fused) - Battery
BROWN - No clue
BLACK - Ground
BROWN w/BLACK Stripe - (no clue)
GREEN w/WHITE Stripe - (-) hood / trunk input (I'm pretty sure)
GRAY - Radar Sensor
RED w/WHITE Stripe - Valet Switch
BROWN w/WHITE Stripe - Door trigger +/- programmable
BLUE - Siren
ORANGE - Starter Cut (I believe it's an armed output, not an alarming output)
YELLOW w/GRAY Stripe - Radar Sensor
GRAY w/BLUE Stripe - Radar Sensor
YELLOW w/GREEN Stripe - ext-2 (I think)
YELLOW w/RED Stripe - LED
BLUE w/RED Stripe (fused) - Dome light supervision (COM)
BLUE w/YELLOW Stripe - Dome light supervision output (NO) (may be ext-3 programmable I think)

DOOR LOCK HARNESS:
YELLOW w/WHITE Stripe (fused) - Parking lights (COM)
WHITE - Parking lights output (NO)
BROWN w/RED Stripe (fused) - Door lock COM
BROWN w/BLUE Stripe - Door lock NC
WHITE w/BROWN Stripe - Door lock NO
GREEN w/RED Stripe (fused) - Door Unlock COM
GREEN w/BLUE Stripe - Door unlock NC
WHITE w/GREEN Stripe - Door Unlock NO


THis SEC-8047 manual has been out from Alpine site, why? dont know, but, also, its possible that this other documents can helped:
- SEC-8028


- SEC-8063

Hope helps with this.

    Thanks for your response. I am not sure if your manual is similar or not. I was told by a local tech that it was different. I know the system works a little, but the locks do not go up and down by remote. There is a connection for the valet and the locks go down when you are driving but that is all. If I push the remote you can hear the sirens until they go off, but beyond all of that ???????????????. I was hopeing to locate a connection for the locks or instructions on what do do.

Three Steps to Determine Door Lock Type
To determine what type of door lock switch you are working with, follow these three steps:

  1. Locate the harness plugged directly into the back of the door lock switch. If there are no external door lock switches, you will most likely have a vacuum type system or an *aftermarket door lock system with relays, or have an added actuator that needs relays.


  2. Next, with your multi meter, probe each of the wires in this harness and write down the readings during lock, unlock, and at rest positions of the switch. Be sure to measure for continuity to ground as well as positive DC voltage and pay close attention to any changes in voltage, resistance, and the duration of pulses. If the switch is illuminated when the lights are turned on, find this wire(s) first and ignore it.


  3. Now compare your readings to those listed below.
Door Lock Types
Single Wire Systems
There may be one, two, or three wires in the harness not counting the illumination wire(s), if any, and only changes in voltage and /or resistance on one wire to lock and unlock. Some of these will open a circuit to lock and ground a wire to unlock. Others will show a difference in resistance to ground or positive 12 V DC during lock or unlock or both. Vacuum type locks will change polarity on a single wire to lock and unlock. ( diagrams )

3 Wire Negative
There are three wires in the harness not counting the illumination wire(s), if any. One wire has continuity to ground at all times. Another wire only shows continuity to ground during lock and (+) 12 V DC at rest. The last wire only shows continuity to ground during unlock and (+) 12 V DC at rest. ( diagram )

3 Wire Positive
There are three wires in the harness not counting the illumination wire(s), if any. One wire has constant (+) 12 V DC at all times. Another wire only shows (+) 12 V DC during lock and ground at rest. The last wire only shows (+) 12 V DC during unlock and ground at rest. ( diagram )

4 Wire Reversal
There are four wires in the harness not counting the illumination wire(s), if any. One wire has constant (+) 12 V DC at all times. Another wire has continuity to ground at all times. A third wire reads nothing at rest, and (+) 12V DC during lock and continuity to ground during unlock. The fourth wire reads nothing at rest, and ground during lock and (+) 12V DC during unlock. ( diagram )

5 Wire Alternating (+) 12 V DC
There are four, five, or six wires in the harness not counting the illumination wire(s), if any. One or two of the wires has constant (+) 12 V DC at all times. One or two of the wires has continuity to ground at all times. Another wire reads continuity to ground at rest, and (+) 12V DC during lock. The last wire reads continuity to ground at rest, and (+) 12V DC during unlock. ( diagram )

Vacuum Type
There is no external switch (switch is contained in the drivers door lock actuator) or it has three wires not counting the illumination wire(s), if any. One wire always shows continuity to ground. Another always shows constant (+) 12 V DC. The third wire changes, reading continuity to ground or (+) 12 V DC depending on the position of the door locks. ( diagram )

Added Actuator(s)
The two wires of the actuator(s) will normally rest at ground, if wired as shown in this diagram, but may rest at (+) 12 V DC. Polarity changes on one wire during lock and on the other wire during unlock.

*If you are dealing with an aftermarket door lock system, locate and measure each coil wire of the lock and unlock relays. Then connect to the wires that activate each relay accordingly. If the system has a relay module, it may also have two wires (pig tail) that will energize the coils of the internal relays. These will usually be negative inputs. Some will have both positive and negative inputs to work with any alarm or keyless entry without the need for additional relays. ( diagram )

Special
These applications will be similar to others, but will require additional connections, parts, or both. ( diagrams )

Hello there top of the morning to you! First of all I just bought a 2000 Audi TT 1.8T yesterday and didn't realize a few things till i brought her home from the dealer. The key fob needed new batteries so...


once you fitted new batteries to both fobs you needed to reset the car.....put key in drivers door and unlock/hold key over(windows go down)wait 30 secs then lock/hold over key,(windows go up)wait 30 secs,then press/hold unlock button for 30 secs.you have just reset the system.you have loads of other little gizmos but i will leave you to find them all good hunting....one side parking lights/driveway illumination/and more.

Security system not working as it used to


i read this on the subaru tech bulletin page
i had the same problem - apparently i had inadvertently put the system into "valet" mode
to get back to normal, unlock with remote - open drivers door - hold down the unlock button on your remote for 2-3 sec - the flashing light will go out and your system should be back to normal
it's too bad the manual doesn't supply information about activating and deactivating "valet" mode
good luck

Reprogram remote


xl-7 programming instructions first you need to stuff your head up under the dash and locate your module drivers side upper corner under dash does it say programmable transmitter (the first models had no programable modules) if it says that then......
1 confirm all doors are shut and key is out of ignition
2 open drivers door insert key and turn to on within 10 sec
3 turn ignition switch to off in 10 sec
4 push and release drivers door switch 3 times in 20 sec
5 turn ign. switch to on in 10 sec
6 turn ign. switch to off in 10 sec
7 press and hold lock and unlock button on transmitter for 5 sec within 20 sec of step 6 alldoors will lock/unlockto confirm correct process
8 press lock unlock buttons on second remote within 5 sec after step 7 once again all doors will lock/unlock to confirm
9 to add another remote up to a max of four repeat steps 1 through 8 this was taken directly out of an owners manual supplement that comes with a new keyless entry kit (part number for a xl-7 or grand vitara can't remember which one it goes to but it works on either one is 84900-67810) which you would have to purchase if yours is not programable these instructions are the same for vitara, grand vitara, xl-7 and the esteem hope this helps

Central locking system


I have recently had this problem I believe this to has been caused by a fault in the drivers door lock assembly It seems this contains the remote receiver. In my case I think there had been some radio interference being the main cause. The remote system seems to be working OK, The door lock will still not operate with the key.
Remove and replace the fuse 25 resetting the ignition module. Starting the engine, switch off remove the key from the ignition, stay in the car lock the doors using the door button, press and hold the remote unlock button for approx 5 seconds, listen to see if you can hear the clicking of the door receiver when you press the remote buttons. Press and hold lock/unlock button. You may be lucky.
