Separator Pulse
WARNING: This page is about a different car, the 1993 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
Single 1/2-second separator pulse is issued 6-9 seconds after last KOEO code. Continuous Memory Codes (soft faults) are then displayed 6-9 seconds after 1/2-second separator pulse. Some digital test equipment may display separator code as "10" instead of "1".
