Xprog UPA R270 etc Repair bricked FRM3

I get many PM’s regarding bricked FRM3 repair. So thought this thread could be a point of information for people who want to repair their bricked module. By bricked I means EEPROM damage through coding / programming due to voltage fluctuation resulting in IFH-0009 error and no communication via OBD.

In this case the module is still good but requires a good EEPROM dump / p-flash being written to it. Once the good EEPROM is in, communication via obd should be restored and vin / VO will need to changed. You also need to find a correct zusb number and flash it with Winkfp.

INFO: MCU is a 9S12XDT384 (mask 3M25J)

DATASHEET – https://goo.gl/bKDpco PROGRAMMERS confirmed to support this MCU: UPA USB Programmer XPROG-M R270 Orange 5

EEPROM DUMPS: My collection of FRM3 dumps – p-flash and EEPROM. https://goo.gl/6dQuCc METHOD: Basically… 1. Erase EEPROM (4096bytes) 2. Write good dump 3. Verify obd working and change vin / VO as if retrofitting used FRM3. 4. Flash with correct zusb number for your vehicle using winkfp.

To connect to the MCU there are 3 methods I’m aware of: 1. In socket – desolder chip 2. In circuit – BDM points – reverse of PCB – see image attached. 3. Direct – test clips onto pins like Pamona Micro Grabbers or cheaper alternative.

Connections to: BKGD RESET VDDR (5v) VSS

Hopefully this is helpful for someone.
