PCMTuner PCR 2.1 Procedure

 PCMTuner supports VW PCR 2.1 read and write. BSL unlock it, then OBD read it.

Module 57

1) Check the current lock status with ECU 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 (PCR2.1) and unlock.

Reading writing can be done with ECU in car.

 

 

PCMTuner PCR 2.1 procedure

1) Check the current lock status with the ecu in the car, by using the ID function. if the check is disabled it will say :

verification check: Disabled

you can read-write with ECU in car.

Otherwise follow the instructions

2) Remove the ecu from the car, open it, transfer the processor to BSL mode using the PCB connection in pictures using 1k ohm resistors. Connect to ECU connector as shown in picture :

Red – +12,

Black – GND,

Yellow – CAN-HIGH,

Blue – CAN-LOW

3) Choose PCR2.1 (EEPROM/UNLOCK/BSL)

4) Click Identification – save ECU data somewhere in a text file.

5) Click Read – save the EEPROM as back up

6) Given that ECU is blocked, we perform Initialization once for PCR2.1 and will get something like this displayed :

Module initialization

Entering programming mode

Transfer bootloader

Examination

The digital signature verification check: Disabled

Done

You can now remove bsl connections and return ECU to car for read /write

 

 

bsl – open ecu, connect resistors
