Service codes are transmitted through STO connector. Service codes are displayed as timed pulses, and may be read with a VOM or Super Star II tester. VOM displays codes by needle sweeps. See Fig. 2 . Turn ignition off. Ensure all procedures of EQUIPMENT HOOK-UP have been followed. Engine should be at normal operating temperature. Fig. 2: Reading Service Codes With VOM Courtesy of FORD MOTOR CO.
