Have VOLVO XC90 with CEM-H, inside = "M30855FW" (CODE FLASH) and "93C86"

Seems that the software (not the hardware) from flash and/or eeprom is corrupted.

can someone "repair" the data so the CEM will be back functional ?

or check the data and confirm that the data is oke...

Thx

Thx, indeed 248742 km AND 2 keys.

i do not have car here, only CEM

The problem with the car = no engine start after the car is 3/4 days NOT active.
it's not the relais, not the starter, not tghe battery
by bridging relais make start the engine !

problem comes from the CEM...

you think (after data = oke) that the hardware is broke ?
