Hello guys! I have a Suzuki Grand Vitara 2.0 2006 with ecu mitsubishi. It has P1621 code stored, and check light blinking. Obviously dont start. I try to write key to the immo with CK-100 - the key is stored okey but the problem still same. I check with Effi Zed Bull, make key to dump and the immobox dump was correct. So must be the ECU dump. I read the 24c04 from ecu and is very strange - there is only first line with data. Can someone help me to pair this dumps or has a working pair? Thanks in advance!!!

Immobox: 33970-65d01 grey mem 24c01
ECU: mitsubishi 33921-65DG1 165DG A9 mem 24c04

Hello! The car is still same. Code P1621. Any other thing i can try? I will try with a new key, also can be wiring or the immobox problem. I found a wire that goes from immobox to the ECU, but i dont now if its correct, dont have the pinout.

Hi,If all goes well with the wiring you had to start the car with my dump.

**shtyrya2** · 28th July, 2014, 07:32 PM

What wiring should i check? Do you have the pinout or diagram?

After installing ecu and immo with your dumps, light still blinking and the immo eeprom changes into this (files attached). Just connect all,put ignition on, and the immobox eeprom changes some bytes. I try two times, both same bytes was changed into different values.

**shtyrya2** · 30th July, 2014, 04:04 PM

Checking the dumps, i can see that the values that changes are ones that also are stored in ecu. So those bytes are the sync between ecu and immo, and they change when i connect the immobox... so it looses the sync. Why?????

The key is Texas 4C Tiris format : 7E F5 29 89 09 00 00 00 00 F5 87 7E 00 00

Please, does anyone have the PINOUT for this immobox? I need to check the wiring, because when i connect the immobox, the content of x24c01 changes and it looses sync.

immobox: 33970-65d01

Thanks!

Try to put the new IMMO box can be a problem in it.

**shtyrya2** · 31st July, 2014, 08:37 PM

I connect the immobox on bench, and now i see i have a dead IC - the S57780 MA. Its a controller for 4C transponder and its a comun fault in japan cars. So i need to get new immo or new IC. Thanks qwertyuiop12, when i have a new immobox i will use your files and let you now.
