Computer Control Module

The computer control module is mounted on the compressor bracket. It controls the compressor relay and vent solenoid. The control module controls power and ground to the rotary sensor. The control module provides a 7-13 second time delay before any circuit can be completed.

The control module monitors air suspension system through inputs from the height sensor and ignition circuits. It limits compressor run time to 2 minutes and exhaust solenoid time to 1 minute. This function is to limit continuous compressor operation in case of severe system leak or a malfunctioning exhaust valve. The timer function is reset when ignition key is turned to the "OFF" and "RUN" positions.
