Reading the 95128 EEPROM
The crash data of this module is stored in a 95128 serial EEPROM (SPI bus, usually an 8-pin package). A complete dump of this chip is exactly 16,384 bytes (16 KB). If your file is a different size, the read is incomplete or a different chip was read.
Read it in-circuit with a clip or with the chip removed, 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 95128 memory of the A2129018801 module with your programmer and save the dump.
- Upload that file here and enter the part number A2129018801.
- 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.
