I will limit myself in my review to a small service instructions for the "Mazda Demio, Bj. 1998 'with existing ZV that can be operated only through the driver's side. Although some manufacturers expected an additional servomotor on the passenger side, but this is not necessary at the Demio. The system itself is well explained, solid and reliable - but I put a little expertise in the assembly forward. Ideally, you have a multimeter (measuring device) as a soldering iron and know each other a little bit so that out.
IMPORTANT: Please use this disgusting NOT "Fuscherklemmen" with which one picks up from an existing cable by squeezing it a signal. The often lead to bad contacts! I always isolating a small portion of the cable, to which I would like (if the cable itself is not cut that goes well and carefully with a lighter), giving the desired cable by either twist it, it solder and insulating the body with either " Rubber Tape "(so an ISO tape that can be extremely stretch, there is in any hardware store) or with heat-shrinkable tubing.
If the battery is disconnected: Please make sure that you eventually needed a code for your radio (still) have at hand!
Install at your own risk!
1) To make sure your testing please if your Mazda Demio also has a servomotor on the driver's side and not just have a signal transmitter. Unlock and open single door. Now with the door open to the pin on the driver's side push down. He has come up again - by itself. If he does: Is everything okay!
2) In the footwell, driver's side at the top left is a black box with a white, wide plug it - this is the control unit for the central locking. The plug can be pretty easily removed by pressing the tab. Deducts the plug and testing whether the ZV still goes: If not, then it is the right plug.
3) At the connector is a green-red and a green-yellow cable. These two cables also go to a connector inside the door panel of the driver's door. Who wants to play it safe: Mounted the trim from. But you can also trade fairs: If you take a normal multimeter (meter) and a measurement tip to the green-yellow cable pressed (just plug of Box deduct and measuring tip to the contact of the plug to keep) and the other tip to ground (Caution: Ignition does not always work, best mass with a small extension cable (jumper cables) from the battery decrease), then the device must be a passage or "short circuit" show (some cheep also) when the pin is pushed down on the driver's side. When green-red cable is exactly the reverse: through if PIN UP (ie ZV open).
4) Now you connect (please with the battery disconnected!) The box of the JOM Central locking with continuous powersupply and earth. If your looking down on the steering column behind the trim: direct right of it is a wider connector. There you will find a thick red and a thin BROWN cables. Red = positive, brown = ground. For safety here also again remeasure!
5) Is the JOM box on juice? Excellent! Clamps the battery briefly and then test whether a "clunk" when you press the remote control off. If yes: Has the JOM-BOX power! Disconnect the battery again.
6) You now separates the green-red and green-yellow cable as far away from the connector ZV box in the footwell of the Demio by - so that sufficient length remains available to solder properly. Before you Solder: Sort the cables please the JOM-BOX, so that it afterwards are not as a tangle of cables! Unused cable: insulate ends and tie them together with cable ties.
NOTE TO CABLES GENERAL:
Pay attention when laying the cables, make sure that no cables anywhere scrub, you can not get stuck accidentally with the foot and is clamped nothing. The cable containing the fuses of JOM-BOX (Plus, control line indicators, etc.) you lay so that you come in case of need to the fuses. Pushes the so somewhere in the "last corner" of the Demio!
7) The ZV the Demio is mass control. So each a ground signal to the severed cable has green-red and green-yellow when opening and closing. By the way: The ZV NOTHING works thereafter per key! The castle itself is YES, the ZV: No. The reason is simple: When you open with key lock on the signal is always at ground, while closing as well. There can be no "pulse" from the outside can be applied because this already is permanently available - but I think: One can cope with! You could get around this by a relay again - but that's what advanced!
8) At the JOM box finds her a yellow and a yellow-black cable. These are the cables on the you can give any signal that then when you press the remote control on the white and black and white wire (opening, closing) is switched through. So you already suspect, which signal to yellow and black and yellow do? Correct: mass! Soldering BOTH CABLES together easily with the you have your box also connected to the power supply to the ground terminal.
IMPORTANT: PLEASE all joints always good INSULATE!
9) the white wire (is a backup between, you need actually only positive controlled ZV) connects her now with the green-yellow cable, the white-black have with the green-red cable that you disconnected from the connector as far away ( Important: Of course, the cables connect go to the plug, ie in the ZV-Box from the Demio).
10) If the test: Connect the battery to make door, press remote control: Runs? Excellent! It goes on!
11) There are two BROWN wire on the JOM BOX. Kappselt gently with a screwdriver the switch for the hazard warning lights on the dashboard. In most cases, you will find on one side of two green cable. Green-red-yellow Gründ (random, one already knows from the ZV). Mostly, these two green cables sit alone on one side of the connector and side by side.
12) removes a piece of the insulation of the two cables (carefully with a lighter or cutter knife), threaded by means of wire both brown cable of JOM-BOX for hazard switch, soldered each a brown cable with a green, isolated everything finished.
13) Anyone who wants can now looking for a suitable job in the Demio, drill a hole with a drill and connect the signal LED of the JOM-BOX. The is a kind of "immobilizer" simulate by flashing. I have this LED mounted centrally above the left vent (the two seated in the middle).
Reconnect HORN AND TRUNK:
If you want, you can still control the hooter as "Alarm" or "search" on the JOM-BOX. I let the conscious, as I look at it as not necessary. Is smart, who buys stronger lifter for the trunk lid - a button is still a channel free for the servomotor of the tailgate individually control - press: "Sssst" - moves the tailgate by itself high. But you do not ;-): Can you make
Good luck and enjoy with your JOM Central locking ;-)
