PCMtuner ECU Operation: Infineon Tricore BSL on Bench

 Here is the PCMtuner Module 53 — Infineon Tricore BSL operation guide by PCMtuner Marty.

MODULE 53 — Infineon Tricore BSL

Description and example operation 1

This module is for qualified users only and requires access to the ECU pcb and in some cases the soldering of additional components. The work is performed in bench mode (BUT ECU disassembling is required).

The module supports many ECU’s with the TC1724, TC1728, TC1736, TC1738, TC1762, TC1766, TC1767, TC1782, TC1792, TC1793, TC1796, TC1797 and TC1798 microcontrollers of Bosch, Siemens / Continental and Delphi ECUs.

The password can be read from SIM2K-24x, Ford EMS22XX, Ford SID20X, Bosch, Bosch GPT ECUs.

The opens to possibilities to MANY ecus not supported by other modules.

Working Example.

For our example we are going to Read and write both Flash memory and EEPROM from a Delphi CRD3.10 in this case, the ecu is from a 2012 Mercedes C250 blue efficiency model, a car not on our current module list.

PCMtuner-Infineon Tricore BSL on Bench

With a little research we can find

  • ECM type and specifications
  • ECM pinouts
  • boot loader connections for pcb

      • Processor type TC1797

      Password: Not implemented

      Eeprom external

      PCMtuner-Infineon Tricore BSL on Bench

      Step 1

      We need to dismantle the ECU in order to access the PCB to enable us to place the ecu in boot mode so that we can read/write.

      First we remove the screws from the ecu case.

      PCMtuner-Infineon Tricore BSL on Bench

      Next, using a heat gun, we gently heat the edges of the ECU lid to help loosen the bonding material, whilst gently prying the lid. Care must be taken not to use excessive heat or force!!

      PCMtuner-Infineon Tricore BSL on Bench

      After removing the Lid we now have access to the ECU’s pcb.

      PCMtuner-Infineon Tricore BSL on BenchPCMtuner-Infineon Tricore BSL on Bench

      Closer inspection of the processor shows it to be a tricore 1797

      Now we must prepare the PCB for boot mode. Below are just some of the Schematics available via online resources on how to place this ecu into BSL or boot mode. Some some will show connections for resistors to be soldered. These type are usually our last resort if we cannot use our boot and cnf cables.

      PCMtuner-Infineon Tricore BSL on Bench

      Others may show the Labels L and H

      PCMtuner-Infineon Tricore BSL on Bench

      and others BOOT and CNF1

      PCMtuner-Infineon Tricore BSL on Bench

      L = Boot H = CNF1 which also relate to the cables on PCMtuner bench wires with crocodile clips.

      In order to connect to the points shown we can use pen probes (recommended ) or we can solder leads directly to these points that are usually pads, vias or IC pins.

      PCMtuner-Infineon Tricore BSL on Bench

      With our PCMtuner interface NOT powered, we can connect or bench cable to the ECU

      PCMtuner-Infineon Tricore BSL on Bench

      And connect our BOOT and CNF1 to the appropriate leads or Probe pens on the PCB

      PCMtuner-Infineon Tricore BSL on Bench

      Step 2.

      Power on our PCMtuner hardware, open PCMflash, and select module 53 TC1797 Micro (4096kb)

      Our Micro is where our flash memory containing maps etc is located.

      PCMtuner-Infineon Tricore BSL on Bench

      Next we click on Identification to ensure our connections and selection is correct :

      PCMtuner-Infineon Tricore BSL on Bench

      If you cannot ID then please check all connections to PCB, check ECU pinouts, or, in some cases you may have to revert to a diagram that shows boot and cnf connections as resistors rather than a physical connection to your bench cable.

      Next we click on Read, We will be asked to select password, in this ECU case we specify that it is not implemented.

      PCMtuner-Infineon Tricore BSL on BenchPCMtuner-Infineon Tricore BSL on Bench

      When read is complete we will be asked to save the file

      PCMtuner-Infineon Tricore BSL on Bench

      click save…

      Now we will read our eeprom.

      In the case of this particular ECU its is an external Ic, so we select the option via MODULE 53>>external eeprom>>Delphi CRD3.1 eeprom

      PCMtuner-Infineon Tricore BSL on Bench

      Again, click Identification..then read

      PCMtuner-Infineon Tricore BSL on Bench

      and again save on the computer when done

      PCMtuner-Infineon Tricore BSL on Bench

      To write a file to flash, we select our micro and click the file selection box

      PCMtuner-Infineon Tricore BSL on Bench

      we then choose the file we wish to write…..

      PCMtuner-Infineon Tricore BSL on Bench

      we then choose the file we wish to write…..

      On this Particular ECU we must do our checksum before in our file editor as this automatic checksum

      PCMtuner-Infineon Tricore BSL on Bench

      So we click Yes

      For our ECU we must select ‘other (no crc checks) in the first drop down box.

      Password is Auto (as not used on this ecu)

      ‘use write optimizations’ is unchecked. This means the full flash file is written. If checked, only changes in the file will be written to Flash — We then click OK

      PCMtuner-Infineon Tricore BSL on Bench

      Sit back, have a beer and wait on your latest masterpiece being written to the ECU

      PCMtuner-Infineon Tricore BSL on Bench

      If all goes to plan….Successful write!!!

      PCMTuner Unlock Audi SIMOS 8.6 in BSL Mode

      Image
       SIMOS 8.6 requires unlocking in BSL mode by the appropriate module. BSL is usually boot mode for unlock. Same as PCR2.1 . Example: Audi A7 2012 2.8 fsi simos 8.6 unlock, after read/write simos8.6 with pcmtuner successfully. all resistor 1 kom How to work with blocks that require unlocking (PCR2.1, SIMOS8.6): 1) Check the current lock status in the car, if the check is disabled, you can go to read-write, otherwise follow the instructions 2) Remove the unit from the car, open it, transfer the processor to BSL mode using the connection below (PCR2.1, SIMOS8.6), the work as a whole as in the package 53 (you can use tools like powerbox, and you can do without them) SIMOS8.6 Unlock pcmtuner pinout Red — +12, Black — GND, Yellow — CAN-HIGH, Blue — CAN-LOW 3) Choose "SIMOS8.6 (EEPROM/UNLOCK/BSL) or PCR2.1 (EEPROM/UNLOCK/BSL)" depending of ECU type 4) Click Identification — save ECU data somewhere in a text file. 5) Click Read — save the EEPROM 6) Given that EC...

      How to Find Bosch ECU Serial Numbers and Correct Pinouts

      Image
       Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify. So all bosch ecus start with serial numbers 028… 026. We just head to bosches page next https://www.bosch-repair-service.com/ Here you search by oe or bosch number, i have random bosch ecu here and it’s 0 281 014 544 and bosch page ends up with a result. We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...

      FoxFlash Read and Write Volvo Denso MB279700-9xxx

      Image
       Foxflash Volvo Denso MB279700–9xxx works perfectly, just follow the steps of foxflash , reading, unlocking, and writing all done on the bench. PROCEDURE: 1 — Read the Ecu AND unlock the Ecu 2 — Write the ECU READING AND UNLOCKING: Connect the following pinout using the multifunction cable. Start the driver: CAR > VOLVO > TOOLS VOLVO >UNLOCK DENSO MB279700 9641 SH72546R CAN Click on the READ FILE button to read the file. After reading, click on the UNLOCK button to unlock and enable the writing of the control unit. WRITING: Now it will be possible to reconnect the control unit to the car and write the modified file via OBD. Use the following driver: CAR > VOLVO > Model >2.0 DENSO MB279700 9641 SH72546R CAN Alternatively, you can WRITE also the ECU on the table using the pinout on the next page. Note: Compared to the read pinout, the CAN line is moved. FOXFLASH PINOUT FOR WRITING: Just follow the foxflash instructions: read file 15 min, unl...
