Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Service Procedure




1. Remove and replace current ECM with the appropriate new ECM referring to pages 6E3-C1-6 through 6E3-C1-7 of the 1991 Geo Storm Service Manual. It is not necessary to perform the "EEPROM" reprogramming in this procedure. The ECMs being used in this campaign have been programmed at the factory and already contain the needed software calibrations.


2. Install Campaign Identification Label.
