MOD: Horn beeps on keyless entry remote lock/unlock

GMJAP · Post by **GMJAP** » Mon Dec 26, 2005 8:10 am

Now, I know many of you are quite happy that the Vibe doesn't make a peep when using the keyless entry remote to lock/unlock it. However, I've always missed the audio confirmation, particularly when locking it. I'm usually walking away from it when locking (so I don't see the lights flash), and often only the driver's door is unlocked, so there's not much of a click to hear. I've come back to it in parking lots several times only to find it unlocked (oops). Also, the other day after I installed this mod I heard it make the "unlock" beep in the driveway as I took my keys out of my pocket in the kitchen. Before, I would've never known I accidently hit it.Essentially what I did was add a circuit that monitors the flasher relay, and gives 1 short beep when it blinks for lock, and 2 short beeps when it blinks for unlock when using the keyless remote. It will not beep when using the hazard lights or turn signals, nor when locking or unlocking using the door switches.If a door is open and lock is pressed, it won't beep so you know something's open (hatch!). (This is because it doesn't blink on lock when a door is open).The downside is the beeps are delayed about half a second or so from after the button is pressed, because it has to wait to see if the blinkers are being flashed once (lock) or twice (unlock). I set it up so it can be disabled without uninstalling it, or set up to only beep on lock (no beeps on unlock). I was planning on using it just in lock beep mode after testing it for a few days, but hearing it unlock when I took my keys out of my pocket has given me second thoughts.The circuit uses a simple microcontroller to monitor the signal to the flasher relay to figure out if it's being sent a lock flash, an unlock flash, or none of the above. To beep the horn, it briefly grounds the horn relay.Since the circuit is more complex than the usual mod, and requires tools for programming a microcontroller, I'm not sure a full how-to discussion is really appropriate here (and might put a lot of you to sleep.) However, for you do-it-yourself'ers I plan on- Following this up with a posting on the details of the flasher relay signals, and getting access to the horn relay signal. (In a day or two)- If you are intersted in details of the module circuitry, IM me (or post) and I'll be happy to answer any questions.- I have enough extra parts to make a few modules, and am thinking of selling them at the cost of the parts, $18, + shipping for anyone that's interested in adding this feature to their Vibe. The installation requires connecting to 2 wires of the flasher relay, and the horn relay wire. I'll include T-Slices (or T-Taps) which just clip around the wires with no soldering or wire cutting. IM me if you're interested.-------- NO MORE KITS AVAILABLE AS OF 8/11/2009 --------This is a clip of the mod "in action" - lock followed by unlock:(the puny Vibe horn sounds extra crappy in this clip)http://forums.genvibe.com/zerofile/9110/Beeps.WMVAnd this is a pic of the module: (The blue jumpers are used to disable it, or set it up to only beep on lock).

Now, that is a great mod! My wife's RAV4 has that audible lock indicator and I've always wondered how it could be done for the Vibe.I don't have the skills/tools to program a microprocessor, so I'll be opting for a hand-manufactured set. I'll IM you later, GMJAP.

Here's info for anyone interested. Apologies for the crappy photo quality. The wife was out with the "good" camera when I did the install. Anyway here's some info on the flasher relay and horn.The flasher relay is found behind the compartment to the left of the steering wheel. Pull up on the drawer when slightly open to pop it out. Note that the flasher "relay" is actually an electronic module that's more than just a relay. The connector is below it (see picture). Press in the tab and pull down to remove the connector.The two wires of importance that I used are White/Black, which is ground, and Yellow/Black, which is used for the lock/unlock flash signals from the MFAM (Multi Function Alarm Module) and the hazard blinker button.The Ye/Bk wire is normally at 12v. The hazard switch connects it to ground continuously when pressed, and the flasher relay does the blinking by itself.However, the MFAM pulses the wire to ground once for lock, and twice for unlock, at the timing given next to the picture below. The easiest place to get access to the horn relay signal is in a wire in the bundle coming down the steering column. It's fairly easy to remove the trim on the bottom of the steering column. There are three screws (see pic below) to remove. Then, grasp the trim from in the hole for the tilt adjustment lever and pull it down to pop it apart and pull it off.(NOTE!!!! - be careful messing with the steering column wires, as the control line to the airbag is in this bundle. Be sure you have the correct wire, and don't unplug any of the connectors. Best yet, disconnect battery negative while working.)The problem here is that the horn signal wire is Green/Yellow, but the cruise control wire is in the same bundle and is also Gn/Ye. How to tell them apart? Well, the 2 of them connect into the steering wheel coil via a connector circled in the bottom right pic, along with a brown wire. The first green/yellow wire is the Horn, the one in the middle (next to the brown wire) is cruise. On mine, the yellow stripes were different widths, so I was able to tell which was which further down in the bundle by the stripe.To sound the horn, connect the Ge/Ye wire (normally at 12v) to ground. This turns on the horn relay and sounds the horn. The pic shows a T-tap being put on the horn relay wire.Hope some of you find this useful.

okay computer fixing took over my weekend....damn you windows!, but i think next weekend ill be able to throw this sucker in and ill make a little write up of it as i was going to wire some switches for the jumpers. thanks again GMJAP

northvibe · Post by **northvibe** » Wed Aug 30, 2006 9:47 am

grr i got this installed but, i have no horn on lock/unlock. When i lock the car no lights blink, but when i unlock they blink twice.Now after initial install when i put the negative battery terminal back on the battery the car beeped, but after that what is above is all it does EDIT: ha it wouldnt blink on lock because my door was open... so my car does everything normal just no horn The only difference between my wire and gmjap's is that his brown on the steering column was my white/black. Then there were the two green/yellow. GMJAP you have a PM

MNMSGALL · Post by **MNMSGALL** » Wed Aug 30, 2006 11:34 am

I had the exact same problem when I first got mine wired up. After thrashing up my garage a bit, I took a look again, and found that one of my wires was loose, so I actually lengthened the wires GMJAP sent and used different splicers on the flasher relay end, and voila....it worked perfect, and has for about 2 weeks now. I will admit, the wires on the flasher harness were the biggest pain in the @## that I have ever encountered! No slack whatsoever by the manufacturer. Anyway, maybe give that a shot....Also, I ended up taking off the vent/trim above to get easier access to the whole flasher relay area.

ZubenElGenubi · Post by **ZubenElGenubi** » Wed Aug 30, 2006 11:51 am

I had the same initial results when I first installed mine (no horn on lock/unlock), but the lights flashed. Turned out that one of my taps came loose.You're right about the limited work space and slack to the flasher...PITA. The only wierd side-effect now is that the horns will beep quickly when I press the Hazard switch.

GMJAP · Post by **GMJAP** » Wed Aug 30, 2006 12:33 pm

northvibe- responded to your PM.As the other guys mentioned, make sure the T-Taps are crimped tightly around the wires, and check that the lug is pushed all the way onto the T-Tap. They need some elbow grease to get all the way on, but then they should cover most of the T-Tap end. My picture in part 5 of the install instructions isn't very good 'cause it doesn't show it all the way on. Since it beeps when you connect the battery, the problem is likely the yellow wire connection.Zuben- Hmmmm..... it shouldn't beep when you press the hazard button. Does it always do that? I'll have to look at it at the meet.

northvibe · Post by **northvibe** » Wed Aug 30, 2006 12:52 pm

well it only beeped that one time, it never has beeped again when putting the battery terminal on. So idk tomorrow Ill take a look again, maybe take off my whole freakin dash cuz yea there is no work space! stupid yota my dad is a electrician and he even looked at it and doesnt know what would be wrong, all the t clamps are very tight and the plug is snug on them :s?

After you have the on/off jumper out for a few minutes, it should beep when you put the jumper back on. If it doesn't, check the white and green wires.Edited - had a brain fart. The top of the board isn't plated, only the bottom, so the test has to be done by shorting one jumper pin to another:PS- you can check white and green wire connectivety by removing the on/off jumper and using a wire, bent up paper clip, or something else conductive to short the jumper pin above "IN=ON" to the pin on the other jumper above "IN=L&U". My 'visual aid':Try both of these tests & see what you get.

This should make the horn honk as long as you short it. If it doesn't, then either the green or white wires aren't making good connection.so have the jumper pins touching the metal of the green and white wires on the bottom?

Do you still have kits? My only concern is disconnecting the Negative terminal of the battery. I have the XM radio with the Moon and Tunes option and if it looses power, the radio security code will have to be reset and it has to be done by a GM Dealer who charges a lot for the service.I have added a pair of Fiamm Freeway Blaster horn and I kept the origional horn for a third note. It sounds great. (Pages 4 and 5 "Tech Info & Do-It-Yourself Info Â» Horn Installation Walk Through")

GMJAP · Post by **GMJAP** » Wed Jan 10, 2007 4:01 am

Still have kits for $20 inc. shipping.The Vibe radios don't have any kind of theftlock on them, unlike most GM radios. Have you had problem with this in the Vibe before? (Is it specific to the XM receiver?)

NCVIBEOWNER · Post by **NCVIBEOWNER** » Wed Jan 10, 2007 4:23 am

This anti theft code does apply to the XM radio. There is reference to this in the manual and the GM service dealer told me that if the battery is discharged or disconnected that the dealer has to get a specific code and proceedure for the specific radio and then they need approxametly an hour or more to install the code before the radio will work again.When I installed the GM Aux in for the radio, the Stereo installer was aware of this and as a result he made sure that the radio was not disconnected from the +12 volt power source.On one of the Genvibe threads I remember reading about one owner who discovered this the hard way and had to go through the above process.

GMJAP · Post by **GMJAP** » Wed Jan 10, 2007 4:34 am

The other option, then, would be to remove the fuses for the circuits related to installing the kit. There isn't any need to remove the radio fuse. I'd have to look up the specific fuses in the service manual later.
