Test FD: Step 1

1) Code 74: Verify Brake Pedal Was Depressed  Code 74 indicates that when the brake pedal was depressed during the KOER Self-Test, the BOO signal did not cycle high. Possible causes for this fault are: brake pedal not depressed during self-test, open brakelight circuit (Batt + side of BOO splice), short to ground, faulty ECA. If brake was NOT depressed during KOER Self-Test, repeat test and depress and release brake pedal ONLY once during test. Depress and release brake pedal AFTER dynamic response code but before brief WOT. If pedal was depressed, go to next step.
