Hello guys,

I have read this suzuki airbag module with jtag, vvdiprog and upa.
Every reading or verification shows about 4 to 10 differences.

Is there a reason for this, and a solution?

Hello to all. Go to drop down menu in upa and select:

Device-----------Settings-----------and set last parameter to ( 1 )

[rob h]

Thank you,

Those are the settings i used before.
And 16000khz
And tried a few different baudrates.

Same verify errors remain.


Is there a section i can skip, and rewrite partial?

[slick_dick]

with this processor i would read only

clear then write

all i know is those bytes that change are needed to be programmed back as read first time.

they should really be empty bytes

Today, i tried a Kia
Renesas RH850 R7F701019x
95910-G6200

Same problem with upa, verify errors, about 5 to 7.

Do i need to remove, ground or bridge something, to get a better reading?

[sanchos]

I have the same problem.
Orange 5 or Smok j-tag
If i read i have 5-7 errors verify.

any idea ?

[slick_dick]

don't verify then.

[sanchos]

))) i kill 2 srs module like this

ok but if i vrite new one dump then if i read again and verify everything is ok.

what pinout did you use to read the module ?
I am trying to read with UPA

[rob h]

Look for the pinout from jtag

sckb jtag only.
Instead using upa or vvdiprog, connect flmd1, you will need to follow pin on print.
