EEC-IV KOEO Test (Key On Engine Off)
How to pull error codes for an EEC-IV equipped vehicle such as the Mazda 626, Mazda MX-6, Ford Probe, Mercury Cougar, Mercury Mystique, Ford Mustang, Ford F-150, Ford Ranger, etc...
In the video I use 3 different methods for pulling codes: jumper wire, test lamp, and code reader (Innova Equus 3145).
This video is for 1993-1995 Mazda 626 2.0L AUTOMATIC TRANSMISSION owners. The 1993-1995 Mazda 626. 2.0L MANUAL TRANSMISSION has a completely different diagnostic system called MECS (Mazda Engine Control System). No matter what type of Mazda 626 2.0L transmission you I do have a forum topic that covers all diagnostic procedures for your needs here: http://mazda626.net/topic/39240-obd-i-obd1-code-reading-or-scanning/
