BOSCH KTS POWER PROBLEM

[mcb58]

Hello Friends,
There is a KTS 550 device with Ubox2 cable. We have problem !!
- Problem is KTS doesnt take power +12v from Cars via OBD cable. no green led when you plug to the cars.Therefore no operation.
-But if you aplly external power (+15v) to KTS via KTS power adapter , green led ligts and work without problems on all cars..
-I checked the ubox2 OBD cable OBD pin16 , takes the power to the KTS box , and i measured the +12v inside KTS box, so No Ubox cable is broken.
-I also checked fuses which i can found inside KTS box, they seems to OK..
As i learnd from market this problem is very known on KTS devices..
Any help appreciated
Thanks

The cable is Ok, problem is in the KTS box i think, Because i measured the cable and the voltage +12v comes from OBD cable to KTS box..

Hi, a friend of mine epirienced such a problem after firmware update ..., I rechecked power circuit inside all was OK. Recheck the power plug connector it has a pin that has extra function, it is connected to gnd when no power is plugged in.... regards ficho

in kts520 is a common fault. I always link inside of the box external 12V with 16 pin obd
