Hello Mate,
What can be the Purpose of the second white LED at the middle of the EZS picture EZS1 as compared to the Pictures EZS2 that has only ONE LED.
Please this question is coming up because i have here the Original EZS1 with 02 LED at the middle which is damaged. I got from a used EZS2 with only ONE LED in which i have soldered the Two MCUs from the Original EZS1.
As result, having programmed the key, the steering Lock ESL unlock, and Dask is turned ON but Starter Motor will attempt to crank just ONCE in less than 2 second and Stop.
I have checked soldering of the MCUs and all OK.So what can be the problem.The EZS

Best Regards

ezs 2 led :1led send signal,1led take signal.
ezs 1 led:send/take signal both in 1.
Thats all.


Fault code in ecu?
Look actual data,ecu atorization status.
Maybe need renwe ecu and agane atorization.

Hello Mate,
Once again thanks for these useful information.
Furthermore, the car Original EZS damaged has a Part Number 2085450108 with 02 LED and i have swapped its MCUs into an EZS with Part Number2105450008 with 01 LED Could it be the reason why there is intermittent cranking?

Once again Thanks for these information.Will scan the car as recommend.Furthermore, you may be right saying that the ECU may need to be renew and adapted, because before changing this EZS, i removed just the EZS and ESL from another car and when i fitted on my car, the starter motor tried to crank for about a second.May be that is when the ECU file was corrupted.

Can the problem also be related to the fact that the car Original EZS damaged has a Part Number 2085450108 with 02 LED and i am using an EZS Part Number2105450008 with 01 LED ?


Best Regards
