Immobilizer
The remote controls have coded chips. The code must match the reader (receiver) in the ignition switch. The car can only be started if the correct remote control with the correct code is used.

Ignition keys and immobilizer
The ignition key must not hang next to other keys or metal objects on the same key ring. The electronic immobilizer could be activated by accident.

Deactivation
When the key is inserted in the ignition switch, the key blade acts on the key-in switch. The key-in switch then forwards 12V from the battery to the central electronic module (CEM) and to the communication circuit in the start control module (SCU). The central electronic module (CEM) then activates the fuel pump (FP). When the signal is received by the central electronic module (CEM), it sends this command to the start control module (SCU) instructing it to check the key. The start control module (SCU) activates the antenna ring and reads off an identification code from the key transponder. This code is transmitted to the central electronic module (CEM) and compared with the codes programmed in the central electronic module (CEM).
If the key is approved, the central electronic module (CEM) transmits a command to the steering column lock module (SCL) to unlock the steering wheel lock. The vehicle cannot be started before the spring bolt in the steering column lock module (SCL) is in the unlocked position. The immobilizer system contains several safety functions to ensure that the steering wheel lock does not lock while driving.
When the steering wheel lock is unlocked, the communication between the central electronic module (CEM) and engine control module (ECM) is checked. This is to ensure that the correct codes are programmed into both control modules. The engine control module (ECM) also checks the identity of the brake control module (BCM) by reading off its serial number. This number is compared with the number programmed into the engine control module (ECM). If these checks are completed satisfactorily, the engine control module (ECM) activates the ignition system. The engine control module (ECM) also transmits a command to the central electronic module (CEM) to allow the fuel pump (FP) to continue to run. If a fault should occur or a check is not approved, the engine control module (ECM) instructs the central electronic module (CEM) to deactivate the fuel pump (FP). The engine control module (ECM) also checks the other parameters covered by the start inhibition function. If all conditions are met, the engine control module (ECM) activates the relay for the starter motor. The engine can then be started.
If any of the above steps should fail, the engine will not start and a message will be displayed in the driver information module (DIM).

Klučavnica vžiga (S40, V50) 172 €, delo 2.5 ure 105 €. Lekše.
Treba je podret celo armaturko, da se pride do ključavnice, kajti ni ob volanu, ampak "tam nekje daleč" v armaturki poleg zračnikov in radia.

Po parih minutah pretepanja ključavnice mi je naposled le ratalo užgat. Kočija je sedaj sparkirana pred Summitom in čaka na jutranji pregled/priklop na tester.

Hja, mene je tudi mikalo bit zraven, pa kaj ko je treba bit na šihtu in to izgubo zaslužit nazaj...

Me pa nekaj zanima - ko so vam menjavali ključavnice, kolikšna sila je pri vas (stara in nova ključavnica) potrebna za obrat ključa v prvo fazo (radio), drugo (kontakt) in tretjo fazo (zaganjač)?
Pri tastari ključavnici je, tako na oko, 100 gramov, 150 gramov, 600 gramov.
Pri tanovi pa 150g, 200g, 100g. Velika razlika napram prejšnji.
(Približno sem si predstavljal silo, potrebno za dvig ustrezno napolnjenega kozarca).

Danes sem hotel vžgati avto(V50 l. 2005, 2.0D, do zdaj deloval brezhibno) in mi napiše samo KEY ERROR, TRY AGAIN.. to je vse.. avto ne vžge, ne da kontakta nič, volan je zaklenjen (skratka vsa varovala proti kraji so vklopljena).. Ključ drugače deluje (odklepanje, zaklepanje..). Probal sem izklopt akumulator da bi se računalnik v avtu resetiral ampak ne pomaga. Probal sem tudi z rezervnim ključem ampak napiše isto. Če ima kdo kakršnekoli izkušnje s tem prosim za odgovore čimprej ker mi avto stoji na parkirišču 25km od doma.

LP!

Tudi pri meni se je pojavil problem s ključavnico. Na postanku na bencinski, probam vžgat, se prižgejo vse lučke, volan se odklene, zaganjač pa miruje. Po približno dvajsetih poizkusih vžge. Nato ga nisem več ugašal, saj sem šel v službo, nato pa sem še nekajkrat probal in je delalo BP. Priporočate takojšnjo menjavo ali lahko malo počakam, dokler se težave ne pojavijo večkrat? Ali je možnost da kar naenkrat sploh ne bo več vžgal?
