Turn Signal Reminder

Radio activates turn signal warning as requested by Instrument Panel Cluster (IPC). IPC sends a class 2 serial data message to radio indicating chime frequency (medium rate) and duration (continuous). Turn signal warning sounds when following occurs:

• Ignition switch is in RUN position.
• Turn signal switch is in either turn position, sensing, within 1 second, an open to battery voltage transition in turn signal control circuit (left or right turn).
• Vehicle has traveled a distance of 3/4 mile (1.2 km) by counting pulses on vehicle speed input circuit.

IPC turns off turn signal reminder when either the ignition switch is turned to OFF position, or turn signal switch returns to Off position, sensing, within 1 second, no transitions from open to battery voltage in either turn signal control circuits (left turn or right turn).
