For 1990-2009 cars

### Key-in-Ignition Reminder

The BCM sounds the key-in-ignition reminder when the ignition is off, the driver door is open (ground signal in circuit 159), and the key is fully inserted in the ignition cylinder (ground signal is circuit 80).

### Fasten-Seat-Belt Reminder

The BCM sounds the fasten-seat-belt reminder for approximately 6 seconds when the ignition switch is in the RUN position, and the driver seat belt is unfastened (ground signal in circuit 238). If the driver fastens the seat belt during the chime period, the BCM stops the chime. If the driver unfastens the seat belt within 6 seconds, the BCM resumes the chime for the remainder of the 6-second period.

### Turn Signal Reminder

The BCM sounds the turn signal reminder once per each flash of the turn signal lamps when the ignition switch is in the RUN position, the turn signal switch is in either turn position, sensing, within 1 second, an open to B+ transition in circuit 18 (left turn) or circuit 19 (right turn), and the vehicle has traveled a distance of 1.2 km (¾ mi) by counting pulses on the vehicle speed input circuit 389. The BCM keeps active the turn signal reminder when either the ignition switch is turned to the LOCK position or 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 circuit 18 (left turn) or circuit 19 (right turn).

### Headlamps-On Reminder

The BCM sounds the headlamps-on reminder when the driver door is open (ground signal in circuit 159), the headlamp switch is in either PARK position or HEAD position (open in circuit 1872), and the key is removed from the ignition switch (open in circuit 80).

### Low Oil Pressure

The BCM sounds the low oil pressure reminder when the IP sends a ground signal through circuit 9901.

### Low Fuel

The BCM sounds the low fuel reminder when the IP sends a ground signal through circuit 9901.
