galletto v52 error wake k-line

[fordy51]

Anyone got any tricks to fix this error?

Tool works fine on BDM as that's all I used it for since I brought it.


Doesn't work on K-line ecu id,read,write
But works fine via Canbus obd ecu id,read,write (very slow for 2mb edc16)

Tried 2 laptops, deleted drivers etc.
Reflowed connections on board and some SMD resistors

I think the 1FW transistor is faulty, but unable to find a replacement?

Anyone able to help

Solution for non-working K-line problem:
Replace 2x smd resistor
Now there is a 2700 trade for 270 ohm
Now there is a 4700 trade for 470 ohm
I change a circuit for HCF40106 HEF40106BT

Why you replace one 270 ohm resistor by another 270 ohm?
Why you replace one 470 ohm resistor by another 470 ohm?
It is nonsense.
Best option is change the hcf by hef and even better give higher supply to that IC. (changing a resistor, the one on the right of U16 which is 103 (10k) to 4k7).

Ok you have right, i have found this quick on some sellers site, my litle mistake

[fordy51]

here is picture of chip, so replace this chip for hef

Also where is resistor to change for better power?

In your photo is below blue resistor in bottom left side.

I see 3 smd. 1002,273, blank.

which of these 3 need changing and too what resistance?

Many thanks for help so far

You go and read my posts in this thread, i already have given GPS position of the resistor

[fordy51]

you say bottom left but there is 3 resistors there haha

[morgano]

R69 change with 4k7

only change resistor or hcf too?

[morgano]

If you can BOTH.

[ruscic]

Mine is v54, can works, boot works, k dont wake, bdm non tested. Resistor and hef fix kline on v54?

[veloseeped]

Mine is v54
Resistor and hef fix kline on v54?

Real V54 has different electrical shema and "resistor fix" not pass for it.

[ruscic]

Is there solution for kline? For v54?
