Reading the R7F701330 microcontroller
This module has no separate EEPROM: the crash data is kept in the data flash of its Renesas RH850 microcontroller (R7F701330). Read it over the serial flash-programming interface with a programmer that supports this MCU.
Make two reads and compare them before you upload, and keep the original file as your backup.
How the reset works for this module
- Read the R7F701330 memory of the A2069007619 0285020772 module with your programmer and save the dump.
- Upload that file here and enter the part number A2069007619 0285020772.
- We remove the crash record and return the repaired file, usually within minutes.
- Write the file back to the module and clear the fault codes.
Before you fit it back: clearing crash data does not repair the car. Deployed airbags, used pretensioners and damaged sensors must be replaced and the system checked fault-free before the vehicle goes back on the road.
No programmer? You can also send us the module. More answers in the FAQ.
