Turn Signal On Warning

The BCM activates the turn signal warning as requested by either turn signal switch. The turn signal warning sounds when the following occurs:
^ The ignition is in RUN.
^ The turn signal switch is in either turn position, sensing, within 1 second, an open to B+ transition in the turn signal control circuit (left or right turn).
^ The vehicle has traveled a distance of 1.2 km (0.75 mi) by counting pulses on the vehicle speed input circuit.

The BCM turns off the turn signal reminder when either the ignition switch is turned to the OFF position, or the turn signal switch returns to the OFF position, sensing within 1 second, no transitions from open to B+ in either of the turn signal control circuits (left turn or right turn).
