Repair of Electronic Ignition Switch 211.

1. Solder out chip from EIS (see the picture below).



2. Put it into programmer (see the picture below).

We use adaptor for programmer, specially designed in the AeroOBD JSC to avoid soldering chip into programmer and out (see the picture below).

3. Connect programmer to the PC.


4. You may see on the PC screen content of the chip (dump) through the programmer software and store it on your PC hard disc.

You may learn more about programmers on the site http://www.etlweb.net/. We use MC69HC912/MC68HC9S12/EEPROM programmer.

5. Launch the Dump Editor program and open the dump file in it.

The Dump Editor program is reading information of dump and shows it on the screen. Edition occurs during saving the dump file (control amounts are counting and so on).

Moreover, the Dump Editor Program allows you to change a run (see the picture below), VIN-code, a key, to write comments.

There is a log file in it, where all the actions are written. There is a search in the log file, so you can easily find any action which has ever been done in the dump.

The Dump Editor Program for the Electronic Ignition Switch allows to copy information to the Key Dump Editor Program to restore the key.

Let's take for example a key, the big one.


1. Take out chip from the key.
