Vehicle Startup

During vehicle startup, the LEDs located on the control unit illuminate for three (3) seconds, turn off for two (2) seconds, then indicate the current parking brake status. At normal startup the parking brake status should indicate that the park brake is set by the LEDs being illuminated. See Fig. After the brake pedal is depressed and the ignition power is on, the driver can release the parking brake.
