SEATS
WARNING
WARNINGS - RESTRAINT SYSTEM
WARNING: To avoid personal injury or death, during and following any seat beltorchildrestraintanchor
service, carefully inspect all seat belts, buckles, mounting hardware, retractors, tether straps, and anchors
for proper installation, operation, or damage. Replace any belt that is cut, frayed, or torn. Straighten any
belt that is twisted. Tighten any loose fasteners. Replace any belt that has a damaged or ineffective buckle
or retractor. Replace any belt that has a bent or damaged latch plate or anchor plate. Replace any child
restraint anchor or the unit to which the anchor is integral that has been bent or damaged. Never attempt to
repair a seat belt or child restraint component. Always replace damaged orineffective seat belt and child
restraint components with the correct, new and unused replacement parts listed in the DaimlerChrysler
Mopar
Parts Catalog.
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column,airbag, seat belt tensioner, impact
sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative
(ground) cable, then wait two minutes for the system capacitor to discharge before performing further diag-
nosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the
proper precautions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death on vehicles equipped with airbags, before performing any
welding operations disconnect and isolate the battery negative (ground)cable and disconnect all wire har-
ness connectors from the Occupant Restraint Controller (ORC). Failure totake the proper precautions could
result in accidental airbag deployment and other possible damage to the supplemental restraint system cir-
cuits and components.
WARNING: To avoid personal injury or death, do not attempt to dismantle an airbag unit or tamper with its
inflator. Do not puncture, incinerate, or bring into contact with electricity. Do not store at temperatures
exceeding 93° C (200° F). An airbag inflator unit may contain sodium azide and potassium nitrate. These
materials are poisonous and extremely flammable. Contact with acid, water, or heavy metals may produce
harmful and irritating gases (sodium hydroxide is formed in the presence of moisture) or combustible com-
pounds. An airbag inflator unit may also contain a gas canister pressurizedtoover2500psi.
WARNING: To avoid personal injury or death, when handling a seat belt tensioner retractor, proper care
should be exercised to keep fingers out from under the retractor cover and away from the seat belt webbing
where it exits from the retractor cover.
WARNING: To avoid personal injury or death, replace all restraint system components only with parts spec-
ified in the DaimlerChrysler Mopar
Parts Catalog. Substitute parts may appear interchangeable, but internal
differences may result in inferior occupant protection.
WARNING: To avoid personal injury or death, the fasteners, screws, and bolts originally used for the
restraint system components must never be replaced with any substitutes.These fasteners have special
coatings and are specifically designed for the restraint system. Any timea new fastener is needed, replace
it with the correct fasteners provided in the service package or specifiedin the DaimlerChrysler Mopar
Parts Catalog.
WARNING: To avoid personal injury or death, when a steering column has an airbag unit attached, never
place the column on the floor or any other surface with the steering wheel orairbag unit face down.

B10B2–A/C COOL DOWN TEST PERFORMANCE (DUAL-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The Cooldown Test checks A/C system performance based on Evaporator Temperature Sensor input. The main cri-
teria is to lower evaporator temperature 11.11°C (20°F) within one minute. Before starting the test, the evaporator
temperature must be above 13°C (55°F) and the front blower speed must be setto high speed. When the test is
running, A/C Select and A/C Request will be on and the A/C status indicator will flash. When the test is complete,
the scan tool will display one or more test status messages to indicate the outcome of the Cooldown Test. A Suc-
cessful Cooldown – Test Passed status message indicates that the main testcriteria was met. A DTC Set During
Routine – Test Not Passed status message indicates that the A/C system is unable to lower the evaporator tem-
perature 11.11°C (20°F) within one minute. A Conditions Too Cold – Test NotRun status message indicates that the
evaporator temperature was below 13°C (55°F) when starting the Cooldown Test. A Blowers Not On High – Test Not
Run status message indicates that either the front blower speed was not setto high speed prior to starting the
Cooldown Test or the front blower speed was changed from high speed to another setting after starting the
Cooldown test. A Refrigerant Temperature Sensor Error status message indicates that a fault occurred with the
Evaporator Temperature Sensor/sensor circuits. A No Results Stored/Test Not Complete status message indicates
that the power was cycled while the test was running.
When Monitored:
When the Cooldown Test is executed.
Set Condition:
If the A/C system is unable to lower the evaporator temperature 11.11°C (20°F) within one minute.

Diagnostic Test
1.DIAGNOSE COOLDOWN TEST STATUS MESSAGES
WereanyofthefollowingstatusmessagespresentafterperformingtheCooldown Test?
Yes, Conditions Too Cold - Test Not Run
If running, turn the A/C compressor off. Verify that the work area ambient temperature is above 15.6°C
(60°F). If not, move the vehicle to a warmer work area. Verify that the evaporator temperature is above
13°C (55°F). If not, set the blower to high speed and allow the blower to run for five minutes. Then, run
the Cooldown Test again.
Yes, Blowers Not On High - Test Not Run
Set the blower speed to high speed and then run the Cooldown Test again.
Yes, No Results Stored/Test Not Complete
Verify that power is not interrupted while rerunning the Cooldown Test.
