ED-18 Battery Analyzer Update Information

(Supersedes 09-027, dated June 30, 2009, to revise the information marked by the asterisks)


Under SOFTWARE VERSION, the method to check the current software was updated.*


The software for the ED-18 Battery Analyzer (or tester) is updated periodically to fix software bugs and enhance the tool's function. To help you

update the ED-18 tester more quickly, Acura no longer distributes CDs for the tester. You can now use the Midtronics ED-18 update wizard to

download software and firmware to your ED-18 tester using a PC and the Internet. It is extremely important to use the latest ED-18 software to

ensure that the current battery testing procedures are used.

Acura introduced a new policy to ensure that ED-18 testers are updated promptly. The ED-18 software must now be updated within 3 days of

receiving notification from an iN message or other Acura communication. If an out-of-date version is used, any battery replacements may not be

covered under warranty.
