Code 74
Expert:  Daniel Wilson replied 2 years ago.
Thanks for the info.
Flash Code 74 indicates that the park brake digital input is shorted to ground between the vehicle interface harness connector and one of the switches (park brake switch, neutral switch, hood switch or optional OEM interlock). ?
If this code is inactive, it may indicate that the vehicle moved during optimized idle operation or that two consecutive engine start attempts were not successful.
Flash Code 74 may also indicate that the relay coil is open or is shorted (causing the unsuccessful engine start).
