help reading HC11F1 (E87J) with clone carprog v.7.28

[shanker1212]

hello everybody please help me read mcu hc11f1 mask E87J existed on opel gm multec (plug purple)
i use a brand new clone carprog v.7.28 adapter A10 .
i used external 12v power supply and disconnected the reset terminal i used 12000k for frequency and tried many frequencies but the carprog kept trying to read with no success
( reading attempt 1...2....3....4...5 ) .
am i missing something ?
is there anyway to read it with carprog .
is there any terminals that i have to pull up beside the reset ?
thank you all .

Show the picture of your connection

i tried what you said " Pin 1 2 3 together gnd still the same , couldn't read.
the connection is as mentioned in the carprog manual.
the brown cable to vss (pin 1 )
the orange mod/b stdby (pin 2)
blue to reset ( pin 17 )
green rx to ( pin 28 )
Yellow tx to ( pin 29 )
red VDD to ( pin 34 )
i tried many times with different frequencies .
i also checked the connections with multimeter for proper conductivity .
best regards and thanks for your help .

After sone hours of disperation I've managed to read/write the MC68HC11F1 inside a IAW 16FM.E6 using carprog. Taught I'd share the solution.

Use the scheme in the carprog manual to connect to the chip and short pins 2/3 MODA/MODB.


Give power to ECU 12V+ PIN 26,35
GND PIN 17,34

That worked fine for me!!!

Hi people i know its old post but i managed to read it with my xprog 5.5.1 and i would like to share solution that worked for me

Lift pins MODA MODB Reset and RxD connect like it says in xprog manual and set oscilator on 16mhZ

So other people wont have headache here is my solution,no feeding 12V etc. Its Opel Vectra Delco ECU

Enjoy :beer:

Dear Stefyhgs,

I am currently trying to read and write the same ECU (Marelli IAW 16FM.E6 from Fiat 600 1.1) and can't get Carprog to read it.
I have connected a spare voltage supply to the ECU pins you provide and have shorted pins 2 & 3 (MODB&A) to ground.
From Carprog, GROUND, TXD, RXD, 5V and RESET pin are connected as described. I didn't connect Orange (MODB) as it is connected to ground already.
There is no communication.

I have checked TxD and RxD with an oscilloscope, on RxD (Green) there is PWM activity once I am trying to connect but not on TxD (yellow), only voltage supply. I have set the parameters to read differently (Oscilator to 4000/8000/16000 and Auto) there is no communication.

Maybe the procedure is wrong? Should I remove voltage supply from the ECU main plug after each attempt?
Hope you can shed some light on this. Already bought a second ECU as I thought the first was faulty.

I have both Clone and Original Carprog.

Best regards,
