Turn Signal Reminder

The IPC activates the turn signal warning as requested by the IPC. The IPC receives a low input signal from the turn signal switch indicating the chime frequency (medium rate) and duration (continuous). 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 IPC 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, 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).
