Clearing fault codes 94 E320

[jcwells]

Greetings:

After completing the repairs on the 1994 E320 I would like to clear the fault codes and get the CEL off, before my emissions test.

I have tried the following:
- Pushed the button on the diagnostic connector for 2-3 seconds, the error code flashes, then I hold down the button for 6 to 8 seconds, repeat for the next error code.

I thought this was the procedure, but the error codes are not erased.

What am I doing wrong?


Thanks,

John
