jimmyberka Posted July 28, 2013 Share Posted July 28, 2013 My service manual says to leave Test mode connetor connected on one page and disconnected on another page, when retrieving codes. Which is it? And, is the test mode connector thr blue one with only one wire on it? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted July 28, 2013 Share Posted July 28, 2013 You can follow the instructions on my website as they give the proper procedure. www.surrealmirage.com/subaru/engine.html To perform the read memory mode, you connect just the black connectors and do not connect the green T connectors. If you want to perform the active diagnostic, you connect only the green T connectors. If you want to clear the ECU memory, you connect both the green T & black connectors.
