hyundai getz no start issue. Imobilizer flashing. fix 

For the getz it is a common issue that the connector plug for the antenna causes too much resistance, this is fixed by bypassing the plug and soldering the wires together directly. For you, you may need to do some further diagnostics, is the imobilizer key light staying on the dash or flashing? . Check out jimthecarguy he has a video on hyundai accent crank no start that can help you check a few things. Like if you are getting spark and fuel, you may need a crankshaft position sensor (another common thing to fail)

If the light is solid it should mean that the immobiliser recognises the key. Does the car crank over normally but not fire? Next time try - leave the car in gear and have a friend rock the car back and forward a bit. Then release the clutch so the tyres drag, like push starting the car(if it's automatic you can turn the crankshaft manually with a wrench) if it starts after that it's the crankshaft position sensor. It also gets a dirty connection, or fails. You can unplug it and clean the connection with electronics cleaner

@@tortron thanks for reply! There is no sound at all when trying to start the engine. No relay clicks, no starter, completely silent. Drove 2 hrs, turned it off for 10 min and it wouldn’t start again. Had a friend help push start it and drove home with no issues. Should I turn the ignition whilst rocking it, or rock to change position of the crankshaft and then try?

@@nRantzau the idea is to get the crankshaft to move a bit and reset its position, key can be on or off, but if the starter isn't turning or even clicking, then that's a different issue. Thr imobilizer on these cuts the fuel if I'm remembering correctly, but if you could push start the imobilizer isn't the problem. With the starter not turning or clicking, I wonder are the leads to the battery tight and thr battery in good fully charged condition? Otherwise check the fuses, and the starter relay

@@tortron I checked all fuses in the engine, hoped it was the ignition fuse- but they all seemed to be working fine when tested. I did not however, check all the fuses under the steering column. Will try that and the starter relay tomorrow. Battery fully charged, in good condition and the leads properly attached. Everything electrical in the car works, aside from the ignition. Thanks for the tips, greatly appreciated!

​@@nRantzau hi mate, i have the same problem with you. What is the problem and how do you fix it ?

The flashing is that it recognises there is a key, but it's not turning the immobiliser off. You should be able to turn the engine over, but it won't start. If your batteries are good, then I think this fix is a good next step. The i30 is a bit different, but I have heard that they also hardwire the antenna ring on them as well, I'm not sure of the exact wiring set up on them

I think that's the same problem, how you describe the lights is what I meant to say I think (but it's been a while) it won't hurt it anyway

Yes, plug the other wires back together like normal

As I understand, The immobiliser is built into the ecu. As far as I know it cannot easily be bypassed

From what I understand, the immobiliser is in the ecu. So it's not easy to bypass. Possibly if you knew what hyundai used to code them you could write the security out (like you can do in holden), but no one has really done it from what I can tell. You may have to get a replacement key, ring and possibly the ecu from a wrecked car

Yeah, you just copy the plug

@@tortron Thanks heaps mate. time to crack out the soldering iron.

Same as mine. I did lost my immobilizer controle ...can't start the Getz...who can help

No. Does the immobiliser light come up at all when the key is switched on? If not it could be an ecu main power issue

Code P1693 is relating to the key chip, ignition transponder, the ecm, or the wiring between them. First, is the battery fully charged? If possible you can try unplug the ecm from the wiring harness and reconnect the plug. Do this 3-4 times, this will help clean any corrosion on the ecm plug connection. If no improvement, try with the plug shown in the video. If no improvement, it is possible there is some damage to the wiring (maybe corrosion or something like a mouse has eaten it) or there is an internal problem with the ecm (maybe corrosion or water damage, or failing capacitors)

Doesn't sound like much of an immobiliser ifnyou can just pull the fuse haha. In these the immobiliser is built into the ecu, I'm not aware of any easy way to bypass it (other things you can program the immobiliser out for example, but there's no available software for Hyundai)

@tortron there's literally a immobilizer fuse in the fuse box lol so figured I'd snatch it out see what p Happens

@diddymonster718 which fuse box under dash or engone bay? And it says immobiliser on it?

@tortron yea I can't post a Pic on here wish I could but it says immobilizer

@diddymonster718 what fuses is that fuse next to. I have not seen that on the diagrams, il check what I think it might be. Again though, the immobilizer is part of the ecu, if there is a fuse for the immobilizer, pulling it would make it fail in the don't start position, if you could bypass it with a fuse they would be the most stolen car
