Turn Signal Reminder
WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
The body control module (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 the RUN position.
- The turn signal switch is in either turn position, sensing, within one second, an open to battery positive voltage 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.
