Monitor Lamp Service Function

1. Turning the ignition switch from OFF to RUN position energizes all system controls and suspends height sensor requests for 7---13 seconds, except for the service monitor lamp which is activated immediately, when the ignition switch is turned to RUN position.
2. The monitor lamp blinks approximately 1.0 Hz jointly whenever the compressor relay is ON.
3. Monitor lamp is kept on at abnormal system conditions for the following Key ON operations:
a. Disconnected rear height sensor electrical connector or any one detached line.
b. Accumulated ON time of compressor motor relay (110---130 seconds).
c. Continuous ON of vent solenoid for (55---65 seconds). If the rear height lowers to or below trim position, the vent operation is reset and monitor lamp turns off, for both Key-ON and Key-OFF operations.
4. When abnormal program run is detected, the control module suspends all controls and the service monitor lamp remains ON.
5. All system functions of the control module, except compressor relay ON, are energized for 29---31 minutes after ignition switch is turned OFF.
6. To reset the system, cycle the ignition switch from OFF to RUN position.
