SERVICE INFORMATION
In the May '06 issue of ServiceNews , we told you about a glitch in the charging system test software for the Honda Electrical System Analyzer (ED-18). (See the article "CHARGING SYSTEM TEST RESULT SAYS RIPPLE EXCESSIVE ") And because of that glitch, we told you if you needed to test the charging system not to use the System test on the ED-18 and to use another approved charging system tester instead.
Well, we've got some good news! We've fixed the glitch. All Acura dealerships will be sent an ED-18 Update Utility Software kit (T/N MTRESU18A2). This kit consists of a utility CD, a 25-pin-to-9-pin interface cable, and a set of illustrated, easy-to-follow installation instructions.
Updating the ED-18 is really a snap. Just hook it up to a fully charged 12-volt battery, load the utility CD into a PC or laptop, plug in the interface cable, push the ED-18's power button, and follow the prompts on the PC's or laptop's display screen. When the update is complete, you'll see SUCCESS...Update Complete! on the screen. You'll also see UPDATE COMPLETE on the ED-18's display screen. It's that easy.
