Ford Fiesta Hacker's Guide - things not in the manual

Pre use your key fob. Press the trunk button TWICE that will unlock only the hatch and all the other doors remain close... You can use it even if the KEY is inserted in the ignition...

I know but it's still a bit awkward with the fob inserted. Mas maganda pa rin may separate switch like those old-style cable release (electronic version).

Lahat naman ng hatchback walang separate release from the inside... Yaris ko wala, Honda Jazz wala. Ang hatchback talaga yung pag bukas nyan nasa labas... Kaya hatchback are called 3 door or 5 door kasi the hatch is considered a door so unlock lahat ng door for better or worse...

Mga sedan owners sila dapat mag isip ng separate switch kasi normally trunk ng sedan should be opened from the inside and not outside. Fiesta lang ata atsaka Mazda 2 yung trunk nabubukas from the outside... Kinuha lang kasi yung sedan body sa hatchback kaya ganun...

I love using the "2 presses on the key fob" to open the hatch.
It even autolocks again when you close it...sweet.

*Vivafoxpro - Nice mod with the autolock
I don't think it would be beneficial for me though.
I often pull out of our driveway, then my wife gets into the car on the road, as we have limited space in the driveway to open passenger door. Everytime I pull out, the car would lock, then I would have to unlock to let my wife in
I think an autolock for me would have to be linked to the speed of the car. Surely this could be offered by Ford via a software upgrade?
If the computer can detect the speed of the car to sound the seatbelt warning chime, then it could autolock at the same time.
With all the technology in this car, it's a bit strange it isn't included in the Asean version, but is included in the US version.

sir vivafoxpro strikes again!

this would be even better! maybe sir viva would be able to tap into the seatbelt warning and switches than the central lock switch?

go! go! viva!

nice one ha, sipag sa pagkilala ng new ride. I like yung ginawa mo sa speed sensing auto lock. Masubukan nga.

My mod worked along the programming of the computer.

The way I understand how the computer works for the boot lock is either:

1. Press the boot unlock twice on the fob

or

2. Press unlock on the dash (which unlocks the doors), then press the button at the boot handle to release the unlocked boot latch.


I do not see a way to have the doors remain locked while the boot is unlocked from the dash.

The best I can offer is unlock all doors including boot then install a parallel switch connected to the boot switch to release the latch. Two buttons needed plus doors will be unlocked.

Precisely. It all boils down to marketing strategies. Companies deliberately "water down" their products so that the more expensive models "appear" better.

I read somewhere a case regarding a TV where the manufacturer deliberately inserted some obstruction unto the speakers to "muffle" them a bit so that they won't sound as good as the premium model. Looking at the replacement part, it had an identical part number as the premium one.

Had you bought an M/T like myself, a crude "speed sensing" is to attach the switch so that the 2nd gear position of the stick bumps the switch.

Shift to second gear, POW - auto lock!

Hindi sya speed sensing Sir. Brake pedal ang trigger. Kung gusto mo speed sensing, tapat mo yung switch sa second gear ng M/T stick mo.

I assume that the computer must send a signal to the seatbelt fixture at a certain speed to check if the seatbelt is engaged in its slot.
Could this signal be "intercepted" and used to trip the dashboard lock button?
It would seem to me that as the computer has the ability to detect the speed of the car already, that would be the obvious mechanism to "hunt down" and be used to trigger the autolock.
That way, it wouldn't matter if you had a manual or auto transmission. I assume the seatbelt warning mechanism is available in all models.

That is a very unique view on how we could surmise how the computer would know the status of the seatbelt slot. The computer sends out a voltage to the slot, then waits for it to return via the other wire.

My own guess is all of these "sensor" points have a fixed voltage always. When a switch is triggered, voltage is sent up the computer. The computer saves one step and just observes if any voltage is coming from the sensors.

This second method has very little electric consumption while cutting complexity in half. The computer not asking anymore, just "listening".

Wiring is also reduced since the first scenario would require 1 wire going towards the sensor plus 1 wire coming back. With 5 doors, seatbelt, bonnet and who knows how many other sensors (ABS has one also), this could really add up.

Second scenario would just have the positive line common to all and send up just 1 signal wire for each sensor.

I think the only way to tell how it works is to open up the drivers side seatbelt slot. It may be simpler than we think. Maybe it has a microswitch in there already
I think we know who we want to volunteer....wink wink

[kevo888]

Just climbed under my driver seat to take some pics of the wiring going to the seatbelt slot.

There are 2 wires, Black and Red, going to seatbelt mechanism.








My assumption would be that the seatbelt slot has a microswitch that is closed when the seatbelt is in use, therefore completing the circuit of the Red and Black wires. The computer then checks this circuit at a certain speed.
If the circuit is not closed, the seatbelt warning will then sound. How we get that to trigger the autolock is one for the experts ie * Vivafoxpro

Update:-
I connected my multimeter to the black and red wires to try and detect a current. (The square plastic connector box can be removed easily by grasping the box from the front, pressing in the buttons on the side, and sliding the box towards the footpedals).
Interestingly, I did not detect a current. I tried with the car, engine running, in D and P without handbrake.
The only way to test it fully would be to drive around with the multimeter connected to see if the current "spikes" when the seatbelt warning chime sounds (I don't have time to do this at the moment).
If it did, and the computer is only sending the current when it needs to check if the seatbelt is engaged, then we have a good signal to trip the autolock

I tried something earlier. When I drive with the seatbelt extended but NOT LOCKED to the clip, I don't get the seatbelt warning. It's only when I release the seatbelt and it runs back in to the pillar that I start hearing the alarm. Can anyone confirm this?

[tidus1203]

Sige when I have the time I will try doing it too hausteam and I will try to confirm back here...

[river enchanter]

regarding the seatbelt chime/icon, once i have tried to connect the belt of the front passenger's to the lock of the driver's and voila! the chime stopped...i guess this is a different twist to hausteam's experiment

sir hausteam, this is not possible on my end. i've tried this long after i got the unit. ang naging solusyon ko sa ingay ay gamitin ang belt sa rear middle passenger. yun ang nakasaksak sa clip para hindi nako si-seatbelt lalo na kung around the village lang ang pinupuntahan ko.

I just found this on a UK forum regarding disabling the seatbelt chime.

"Turn the ignition to position 2 and buckle and unbuckle drivers seatbelt 9 times. The light in the cluster will flash 3 times"

Source - http://www.fordownersclub.com/forums...howtopic=17854

Or just push another buckle in the slot, either rear belt or passenger.
Please don't turn this into a discussion on seatbelt wearing. I just posted this for anybody that is interested. I always wear my seatbelt, so don't need reminding, but I will leave the chime enabled anyway.
