KT200 Read and Write PCR2.1 both Bench and OBD mode no problem.

1. Bench mode: OK 

Question: How ECUHELP KT200 ecu programmer Read and write pcr2.1 on Bench? Do I have to unlock eeprom first and after reading and writing normally? What is the process for using the KT200 ECU programmer to read and write PCR2.1 on the bench? Do I need to unlock the EEPROM first before proceeding with normal read and write operations?

On Bench, you can first read the EEPROM and immediately rewrite it. This will automatically unlock the software, allowing you to read the flash and write modified flash. Have done many on Bench, and is relatively straightforward. However, it is recommended to use a better power supply for optimal performance.

Tips to unlock pcr2.1 on Bench:
Please first encrypt before unlocking pcr2.1 on Bench.

 

2. OBD mode: OK

KT200 is possible to read and write pcr2.1 via OBD, it can be a lengthy process that requires careful attention to instructions.

For visual guidance, please watch the videos here:

Tips to unlock pcr2.1 via OBD:
Take Audi A1 1.6tdi PCR2.1 unlock via obd for example:
-Choose “unlock via obd”
-Read “VR file”
-Write “VR file” and apply the patch
Be aware audi a1 battery in boot, so prepare before writing just to save time
It took 17 Minutes

Then went to the option “Read / Write”
Done – read – fast
Modified file
Wrote modified file – 3 minutes

FAQ:
Q: When using KT200 to unlock pcr2.1 by obd, got the error “virtual file not present in database” and on bench nothing happens when he tried to read.

Image 2: try to unlock pcr2.1 on Bench

Possible reason and solution:
1. Low power supply, add to 13V power supply.
2. wrong checksum, better manually do checksum via Winols / Lsuite/ Davinci.

Q: When attempting to use KT200 ECU programmer to write VW Simos PCR2.1, there is no response from the system, and I receive the error message “ECU LOCKED by EEPROM/FLASH” as displayed below. Could you kindly provide guidance on resolving this issue?

What to do next:
Unlocking PCR2.1 with ECUHELP KT200 via OBD or on Bench

Prepare:
Before proceeding with unlocking PCR2.1, it is crucial to take a few preparatory measures:
1. Encrypt before unlocking pcr2.1 on Bench.
2.Give 13V power supply instead of 12V, 12.4V etc.

Please ensure the correct checksum.
Method 1: ECUHELP KT200 unlock PCR2.1 on Bench or via OBD.
Connect the bench box v.2 to the tool and connect the
multifunction cable as follows:

To read and write use the following driver:
→ BENCH MODE
→ VW / AUDI / SEAT / SKODA
→ TC1796 – VAG
→ SIMOS PCR2.1

ATTENTION:
In addition to reading/writing the full backup, you can also use this driver to unlock the serial write for the OBD driver “R/W MAPS”:

By loading the EEPROM file, if the software sees that the Eeprom is locked, the following message will be displayed:

Set unlock EEPROM for
serial maps programming?

Choosing OK will apply the unlock on the EEPROM and you can also write the ECU in OBD using the serial driver R/W MAPS.

We also remind you that you can also read and write PCR2.1 via OBD using the driver:
SIMOS PCR 2.1 ONLOCK BY OBD *CAN
This driver reads the file with virtual read and unlocks the control unit directly while writing by applying a patch on the micro file during writing.

Method 2.ECUHELP KT200 unlock PCR2.1 in boot

SIEMENS SIMOS PCR2.1 [ TC1796 INT.F.] – VW, Audi, Seat, Skoda

ATTENTION:
From now on it’s possible to read/write a full backup of the control unit and unlock the serial write for the “R/W MAPS” driver without opening the ECU
directly from pinout using the driver in the BENCH MODE section of the software.

We also remind you that you can also read and write PCR2.1 via OBD using the driver:
SIMOS PCR 2.1 ONLOCK BY OBD *CAN
This driver reads the file with virtual read and unlocks the control unit directly while writing by applying a patch on the micro file during the writing

Below we show how to connect via Boot:
Kit to use:

Multifunction cable
2 resistances of 560 Ω
1 resistance of 1000 Ω
PASSWORD SEARCH:
Connect the pinout below with multifunction cable.
Use the driver:
→ TOOLS BOOT MODE
→ INFINEON TRICORE Tool Password
→ PASSWORD SIMOS PCR2.1
→ Click on “Find Password” and follow the software messages.

Now that the password has been found it’s possible to read and write the control unit. See the next step.

READ AND WRITE ECU:
Connect with the multifunction cable the following pinout and the boot shown below.
Use the driver:
→ TOOLS BOOT MODE
→ INFINEON TRICORE Boot
→ SAK TC1796
