Turn Signal on Reminder

The BCM sounds the turn signal reminder once per each flash of turn signal lights when these conditions are met:
^ The ignition switch in the RUN position.
^ The turn signal switch is in either the left or the right turn position (sensing, within one second, an open to B+ transition in either circuit 18 or 19).
^ The vehicle has traveled a distance of 1.2 km (3/4 mile) by counting pulses on the vehicle speed input circuit 389.

The BCM keeps active the turn signal reminder until one of these conditions is met:
^ The ignition switch is turned to the LOCK or OFF position.
^ The turn signal switch returns to the off position (sensing, within 1 second, no transitions from open to B+ in either circuit 18 or 19).
