When I try to read eeprom chip it says ''unknown device'' if I de solder the chip and try to read I get the same error message
I ordered 4x 74HC125M / manufacturer TI / and I got 4x 4x 20190925_151852.jpg57CG4NK HCT125, is this good?
When I try to read eeprom chip it says ''unknown device'' if I de solder the chip and try to read I get the same error message
Hy to all .today my carprog start units left .... Need to reflash ?
hi mates, I can't understand a thing about car prog, in practice I made a clear of an eprom airbag everything went well, these days I had a twin eprom on which to clear, but when I write the same clean file that I have already used verification after writing goes wrong. why?
please can you help me understand this?
thank you so much !!!
Hy to all .I find this tutorial about flashing carprog without lift the pin 55,remove the At88sc .Someone try this ?

I did all the tutorials regarding the flashing of the carprog. I tried the method that I posted to you. It is functional, I just simplified and modify the flashing procedure for that it is simple for the novices (I am one myself).
I just observed and tested the different methods in order to arrive at something simple steps.
1) No need to unsolder AT88SC.
2) no need to lift pin 55 or solder a wire on the pin 55 (according pcp) .
3) the reset is done on a single pin as in the photo.
4) photos of the connector that I made.
I did not put you the flashing procedure (there is a lot of post on this subject). I use the segger software “flash V 4.98” and of course the segger interface jlink .
PS look at the photos and make sure you have the same pcb. have a good flashing.

Does anyone have success with gm airbag modules that have 9s12, 908 and other motorola MCUs ?
All the times I tried clearing them with carprog always had errors
Jelp I have tried various caps on antenna to fix it to work without "Antena not connected" error which comes instantly as i hear antenna relay click so its then HTRC110 IC side when try PCF or ID48 reading?
Example Texas chip no problem reading and i am understanding it is done by other chip beside HTRC110.
Does that chip go through those logic chips which needs be replaced for EEPROM reading too (74HC125D)?
As i do measure antenna via relay pins it is 5.6 Ohm. Antenna itself reads same too as direct reading. Tester says 0.21mH And i have 7.7nf now there as setup.. tried larger and smaller values and no difference.. so chip itself records antenna fail bit as true for some reason maybe.
Chip itself gets 4.6V as Vdd.
Could that HTRC110 chip be bad? Replace it with another or PCF7991AT chip.
Test of Carprog says OK on first and D1 tests.
Update: Found a problem.. trying fix it. Once got smoke out bit but still works as i was faster than smoke.

Is possible rework Carprog to read/write Fujitsu MB91F MCU? .
hy all ,i need pin out for a ford kuga dash 8VT - 10849- LK to power up by bench also i want to read MC9S12XHZ512 to read km with carprog
I got reading to work. After did change those 4 chips AND the HTRC chip it started to try (Transponder signal low) and after fine tuning antenna it reads and writes finally time to time.
please dump without at88 (erased) higher than 4.01?
Have someone software for j-link china ? I cant find it in my software base... meybe delete many days ago
