I try that one but tango say unknown version and VVDI say wrong ISN

[Josue]

I have tried with VVDI2 and if it has given me the ISN

[davorOS]

Can aanyone check and correct this flash dump
looks like someone try to downgrade CAS and flash is damaged

I made new key and remote work but I can't get ignition
dump from CAS

only one thing I'm not sure is CAS eeprom ISN have two bytes different then ISN in ECU
this is correct or not

CAS ISN AC 857A 9FBA6EAB 394464427B 2688 3418
ECU ISN AC 857A 9FBA6EAB 394464427B 2699 3418

THANK YOU

Test this Flash, it work with your CAS number

[davorOS]

still same
remote work but no light on dash

[lion0304]

There are 2 solutions:

Update the CAS

Or find another used then clone Flash + eeprom

[davorOS]

thank you but I allready try that I also try new CAS but same
I think I have problem with terminal 15 but I can't find where is a problem
fuse and relay are OK most be electrical problem

You have any error in dash when you insert the key?
Did you try to make elv off?

[davorOS]

only fault I have is CAS internal fault
I also try to add ELV emulator but same situation
when I insert key to slot no lights on dash,like dash is dead but when I press button on dashboard display work so dash is OK
I don't remember fault codes in dash but I will plug in diag in morning and check

car work before customer lost key after that car is dead

i was lucky last week auto AA guy walked away from a job someone else touched and I easily solved glad autohex restored cas

[davorOS]

hello
still fighting with this one
I now have lights on dash and car crank but not start no faults in CAS
can anyone check ISN in CAS and ECU?
AVDI say dme>cas synhronization OK but I'm not sure

try cas => dme sync with other diagtool the avdi.
sometimes avdi say is oke but is not.
and you use other tool and is oke.

[davorOS]

I will try other tool
VVDI say synhronization not possible

only fault I can't clear is A54D FUEL PUMP CONTROL MODULE
I will have to find control module to test
