Hi folks,

I post this thread about 6 hours earlier, but after 10 minutes it went blank and admin didn't respond, so here goes attempt number two:

I'm installing this remote starter system in my 2006 Suzuki Swift. I've done one of these before (different car), and everything has gone perfectly so far except for the immobiliser bypass. I bought an Xpresskit security bypass (pictured below) but the "2006 Suzuki Swift" instructions that come with it don't match the wire colours in the car. Grrr.



This is the immobiliser receiver:

As you can see there are four wires on the immobiliser receiver (where the key slots in) and the Xpresskit says I need to tap into the "Ignition" (not very specific) and the "Data" (again, not very specific!).


Anywho, I put my multimeter across the pins of the plug as shown below and this is what I got:

(UNPLUGGED + IGNITION OFF)
Pin 1 / Black+White wire: 0.00 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +0.08 v
Pin 4 / Yellow+Orange wire: 0.00 v

(UNPLUGGED + IGNITION ON)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +12.18 v
Pin 4 / Yellow+Orange wire: 0.00 v

(UNPLUGGED + IGNITION ON but NO KEY in RF receiver)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +11.80 v
Pin 4 / Yellow+Orange wire: +11.39 v

(UNPLUGGED + IGNITION ON and KEY in RF receiver)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +11.80 v
Pin 4 / Yellow+Orange wire: +11.39 v

Do those changes in voltage mean anything to anyone in determining the "ignition" and "data" wires?

I've sent a long email to XpressKit to see if they can help.

For the timebeing I've just taken the RF chip out of the spare key (the black rectangular thing I'm pointing to) and adhered it to the RF/transponder receiver next to the keyhole.


I'll use this quick-fix until I hear back from someone here or from XpressKit to solve the immobiliser bypass problem (the RF chip is on the left, next to the word LOCK).


Obviously this means the car is operating without its immobiliser system so it's possible to hotwire the car at the moment. You can't tell that from looking at it however so I'm not too concerned for now.

I just thought you might enjoy seeing how simple it is to temporarily override the immobiliser if you have one of the RF chips on hand.

Correction on my first post. The numbers are the same, but I mistyped the plugged/unplugged order.
These are correct:

(UNPLUGGED + IGNITION OFF)
Pin 1 / Black+White wire: 0.00 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +0.08 v
Pin 4 / Yellow+Orange wire: 0.00 v

(UNPLUGGED + IGNITION ON)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +12.18 v
Pin 4 / Yellow+Orange wire: 0.00 v

(PLUGGED IN + IGNITION ON but NO KEY in RF receiver)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +11.80 v
Pin 4 / Yellow+Orange wire: +11.39 v

(PLUGGED IN + IGNITION ON and KEY in RF receiver)
Pin 1 / Black+White wire: +12.18 v
Pin 2 / Orange+Black wire: Earth
Pin 3 / Yellow+Black wire: +11.80 v
Pin 4 / Yellow+Orange wire: +11.39 v

Also, here are the model details for the transponder unit if this helps anyone:
33970-62J00 GB
SIEMENS VDO 5WK49181
