Abs/Atc System (Anti-Lock Brakes); Front Axle - Monaco Cayman 2005 Owner's Manual

ABS/ATC SYSTEM
(Anti-lock Brakes)
The Hydraulic Antilock Braking System is an electronic wheel speed
monitoring and control system. The Electronic Control Unit (ECU),
located in the battery compartment, receives and processes signals
sent from the wheel sensors located on each of the wheels. The ECU
will process the signals and generate the commands to the solenoid con-
trol valves housed in the Modulator Assembly used to control the brake
pressure. This process occurs when the wheels begin to lock. The rapid
valve operations may even be noticed in the brake pedal.
The ABS indicator light located on the dash will alert the driver to
possible system faults and is used by service personnel to assist in trou-
bleshooting. In the event the ABS indicator light remains illuminated,
normal braking is not affected. However, the ABS system may not
function correctly in a panic stop. It is recommended to drive with
caution and obtain service on the ABS system as soon as possible.

FRONT AXLE

While driving the motorhome, be aware of any changes in the feel of steering and have the system
checked if there are any apparent differences. It is normal to hear some hydraulic noise from the steering,
especially when the steering is at maximum or while turning the wheel when the motorhome is not mov-
ing. Investigate any unusual or loud noises that occur. Begin by checking the hydraulic fluid level.
Traveling at slow speeds over rough surfaces may cause a "clanking" noise to emanate from the steer-
ing column, but if noise is heard on smooth surfaces while turning back and forth sharply, the noise
should be inspected and repaired as necessary.
Shimmy and looseness should be checked and corrected as soon as possible. If any looseness is felt in
the steering, the steering linkages can be observed while someone turns the steering wheel left and right.
Watch the linkages for any evident play or uneven interaction between components to help pinpoint a
problem. Have the steering system checked for damage after a severe impact, such as striking large pot-
holes or curbs, and front-end collisions. Observe the alignment of the steering wheel spokes; a change in
the alignment may indicate damage to the steering components or suspension.
