Turn Signal On Warning

The BCM sounds the turn signal reminder once per each flash of the turn signal lights when these conditions are met:
^ The ignition switch is on.
^ The turn signal switch is in either the left or right turn position (sensing, in the past 2 seconds, a turn signal on signal via the Class II serial data link.)
^ The vehicle has traveled a distance of 1.2 km (3/4 mile) by sensing vehicle speed signals via the Class II serial data link.

The BCM keeps active the turn signal reminder until one of these conditions is met:
^ The ignition switch is off.
^ The turn signal switch returns to the off position (sensing, in the past 2 seconds, no turn signal signals via the Class II serial data link.)
