How to Repair VW DCM6.2V No Start Issue on Foxflash

 Problem: How do I read and write down a driver in a vw dcm6.2v with foxflash in boot mode, because after installing stage 1 (via OBD) the car does not start and I can’t bet anything?


Foxflash VW DCM6.2V ECU Car Not Start Solution

Solution:

That situation usually comes from checksum handling or wrong patch area — DCM6.2V is picky.

If you can still read and connect to ecu, write original file, test if it starts.

If yes, then manually checksum the file and write it back. If it still causes problems solution is not good (bad file).

Foxflash don’t have bench or boot protocol for this ECU.

You can also take boot read and restore ecu.

 How to read a Chevrolet SIM2K-D160 ecu with pcmtuner ? Use this in Module 30, 1,3,5 — ECU ground (just connect one of the contacts) 77 — CAN-High 78 — CAN-Low 76 — K-Line 2 — +12V (ignition on) 4 — +12V (power supply of the main relay) 6 — +12V (non-switchable power supply) You may not be able to do this ECU in BSL 53 as main processor is MPC756MXP56 Second Processor TC1738. You could try OBD Module 30 Kia/Hyundai SIM2K 2.0L, 2.5L (SIM2K-D160) But failing that, you would have to do this in BSL mode 53 http://www.pcmtuner.org/pcmtuner-module-53-infineon-tricore-bsl-operation/
