alaska_mech Posted October 2, 2017 Share Posted October 2, 2017 Hello all. New member here. I have a 98 Pathfinder, and recently it fried the part of the ECM that controls the fuel injectors. I want to replace the ecm and have found one on ebay for under $100. The question I have is do I have to reprogram, or reset. It does not have keyless entry, or at least I don't have a key fob for keyless. Any input would be appreciated. Link to comment Share on other sites More sharing options...
RCWD21 Posted October 2, 2017 Share Posted October 2, 2017 As long as it's an ECU out of a 98 or similar model and an automatic transmission model it should work just fine. If yours is a manual transmission model you should be fine with whatever ECU you get. Keyless entry is handled by a separate unit entirely so no worries there. Once you get a new one I'd still clear it with a scan tool just in case the previous vehicle has stored any codes. 1 Link to comment Share on other sites More sharing options...
