The function of the Automatic Level Control (ALC) system
is maintaining a constant trim height at the rear suspension when the vehicle
is loaded beyond a predetermined amount. The ALC system is active with
the vehicle ignition switch in the ON position. The system consists of
the following components:
• | An automatic level control sensor |
• | Automatic level control air lines |
• | An automatic level control air compressor assembly, consisting
of the following components: |
- | Automatic level control air compressor motor and head |
- | Automatic level control air compressor bracket |
- | Automatic level control air dryer |
- | Automatic level control Air dryer filter |
- | Automatic level control air compressor relay |
- | Automatic level control air compressor filter |
An inflator system is included as part of the overall ALC system. The
function of the inflator system is to provide air under pressure up to 482 kPa
(70 psi) to an automatic level control solenoid valve for the purpose
of inflating items other than the vehicle air shocks, such as sports balls,
bicycle tires, automobile tires, etc. The automatic level control solenoid
valve and the automatic level control inflator air switch are located behind
the passenger-side body-side trim panel. The inflator system is active
with the vehicle ignition switch in the ON position. The inflator system
consists of the following components:
• | An automatic level control solenoid valve |
• | An automatic level control inflator air switch |
• | An automatic level control timer relay |
