2007 JEEP COMPASS ECU

Inspect all hose connections such as clamps and cou-
plings to make sure the are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could cause failure.
Fuel System Connections
Electronic Fuel Injection high pressure fuel systems are
designed with tubes and special connects, connections
and clamps which have unique material characteristics to
provide adequate sealing and resist attack by deterio-
rated gasoline.
You are urged to use only the manufactures-specified
tubes, connections and clamps, or their equivalent in
material and specification, in any fuel system servicing.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Section.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake And Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard and

brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.NOTE:Inspection of brake hoses should be done when-
ever the brake system is serviced and at every engine oil
change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
