Problem:-2nd hand Hyundai 159.000 on the clock???
Fault .....Suddenly ,intermittently wont start. just cranks over and that's all
Did a massive google search and found its a common fault but no one explains how to fix it?
Some reference to the immobiliser.
When you stick the key into the ignition and turn it on, there is a micro chip in the key that wakes up to the induced voltage from a COIL at the top of the key barrel on the steering column (.Not the same as the battery that sends a wireless signal to open the doors.)
When the chip wakes up it sends a coded signal to the immobiliser and that turns on the electronic ignition and the car starts.
One blog said the wires need soldering on the COIL plug.
Well fault got so bad today that 50 tries would not start the car.
I pulled off the steering wheel covers (a trick on its own ,Turn steering wheel to remove screws ,parcel tray must come off too) and then car would start every time, so a poor connection looked a possibility. Then I cut out the connector plug and bypassed with straight wires.This seems to have fixed it
Raining and dark now, so see how it goes tomorrow??
Bloody hope it works.
You have found the problem and the solution.
See my post copied below from another thread:
Getz intermittent starting Message from Silver Getz:
Hi, I have an 08 Getz that has been having intermittent faults with the immobilizer. When the ignition key is turned to the on position the immobilizer warning light will flash once and the engine is ready to start. However very often the warning light will flash 5 times and then the engine will crank but not start.
The owners manual says that if the immobilizer warning light flashes 5 times it has a fault and needs to be taken back to the dealer. The first time returned to the dealer they couldn't find anything wrong( at that stage it had not been discovered it was an immobilizer fault), the second time they reset " the immobilizer" and it was fine up until 3 months ago.
Again we are having the same problem and it's getting progressively worse with many attempts to start. It has been back to the dealer and they reprogrammed the keys and replaced 1 key. On picking it up from the dealer the same no start fault occurred in their car park so we are back to square one.
Has anyone here had any experience with this problem?
My post in reply:
My wife's 2008 Getz had this starting problem which required her to make many attempts first thing in the morning. It appeared to be an immobilizer problem.
After searching on this forum and others, it seems to be a common problem worldwide - and with other Hyundai models too. In some countries the dealers know of the problem and fix it under warranty.
The cause is poor contact in the connector bock for the immobilizer coil.
I took the details to the regional Hyundai dealer and asked them to fix it under warranty, especially as it a known problem as shown on my forum print-outs.
Basicly, they were unhelpful, said it was not a common fault, said they would need to do a fault scan etc and it would not be covered by warranty. I was disappointed that the people we spoke to seemed not to understand the details of how immobilizers work and, worst of all, the poorest customer care attitude of any main dealer I have encountered.
My wife took the car to a local independent garage with instructions to remove the immobilizer coil connector block and solder the connections permanently. The cost was a fraction of that required by the Hyundai dealer to make just a fault scan.
Six months on the car still starts first time every time.
As a qualified professional electronics engineer I was horrified to find that Hyundai had used a general purpose connector intended for a few amps in a situation that carried only a few milliamps. The correct connector should have gold plated contacts. The one fitted will go high resistance at low current due to atmospheric corrosion over time. This also explained why some people have had only a temporary fix after garages have disturbed the wiring.
SUMMARY
Car difficult to start when cold overnight (car 4 years old).
One of the dashboard light was not illuminating correctly (immobilizer) but not noticed until we started to investigate.
Cause is wrong type of connector used on the wiring of immobilizer coil.
Solution: Cut out the connector bock and solder the wires direct.
Sorry it's a long post but I hope the details will help other Hyundai owners, and not just the Getz. Thanks to other forum members for pointing me in the right direction.
