900 L4-1985cc 2.0L SOHC (1988)
If the motion sensor has been disabled on the 1992 9000 alarm system, the alarm will chirp whenever the drivers door is locked as a reminder that
the motion sensor is inoperational. The chirp will occur if the motion detector is disabled temporarily (by holding the key in the locked position for
3 seconds) or permanently (by using the procedure on p. 70 of the 1992 9000 News Book). This is a built-in feature of the system and does not
indicate any malfunction.
