The 4-Wheel Anti-lock Brake System (4WABS) module is on the ISO 9141 communication network. The 4WABS module controls the brake pressure

The Automatic Ride Control (ARC) system is a computer controlled suspension system. The front and rear shock absorber contains an integrated air
spring. The front and rear air springs provide automatic load leveling and a ride adjustment with a total span of 50 mm (2 in).
The ARC module programming has a time delay compensation for normal suspension travel over rough roads so the ARC system will not attempt to
continuously adjust vehicle ride height.
There is one height sensor mounted in the front and rear of the vehicle. The height sensors have a total travel range of 80 mm (3 in).
