TEST ACTION APPLICABILITY
1NOTE: If DTC P1611, P2306 or P2332 is present with this DTC, diagnose
DTCs P1611, P2306 or P2332 before diagnosing this DTC.
NOTE: If the ECM detects and stores a DTC, the ECM also stores the
engine/vehicle operating conditions under which the DTC was set. Some of
these conditions are displayed on the DRB at the same time the DTC is
displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to
duplicate these conditions may assist when checking for an active DTC.
NOTE: The engine oil must be at the proper level for this test to be valid.
Refer to the Service Information and ensure the engine oil level is at the
specified level.
Turn the ignition on.
With the DRB, erase ECM DTCs.
Start the engine several times, letting the engine run for at least 30 seconds at a
time.
With the DRB, read ECM DTCs.
Did this DTC set again?All
Ye s!Go To 2
No!Go To 10
2WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
Refer to any Technical Service Bulletins (TSB) that may apply.
Turn the ignition off.
NOTE: This DTC implies that the engine may be contaminated by water,
engine coolant or other material due to a mechanical or service failures
such as failed gaskets, seals, cracks or incorrectly installed components.
Inspect the engine for conditions referred to in the above note.
Were any of the above conditions present?All
Ye s!Repair as necessary.
Perform ROAD TEST VERIFICATION - VER-2.
No!Go To 3
3 Turn the ignition off.
Disconnect the Engine Oil Sensor harness connector.
Turn the ignition on.
Measure the voltage of the Engine Oil Sensor Signal circuit.
Select the appropriate voltage reading.All
Voltage is above 5.4 volts.
Go To 4
Voltage is between 4.7 and 5.4 volts.
Go To 5
Voltage is below 4.7 volts.

DESCRIPTION
PARTS AND LUBRICANT RECOMMENDATIONS
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 1) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
ªGº. Chassis lubricant is identified by the latter ªLº.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.
When service is required, DaimlerChrysler Corpo-
ration recommends that only MOPARtbrand parts,
lubricants and chemicals be used. MOPARtprovides
the best engineered products for servicing
DaimlerChrysler Corporation vehicles.
AUTOMATIC TRANSMISSION FLUID - NAG1
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
Use ATF approved to MB 236.10, MB 236.12, such
as Shell ATF 3403/M-115, MOPARtpart number
05127382AA, Fuchs/Shell ATF 3353, or equivalent.
Automatic Transmission Fluid (ATF) is red in color
when new. The ATF is dyed red so it can be identified
from other fluids used in the vehicle such as engine
oil or antifreeze. The red color is not permanent and
is not an indicator of fluid condition. As the vehicle is
driven, the ATF will begin to look darker in color and
may eventually become brown.This is normal.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.

VALUBRICATION & MAINTENANCE 0 - 1
Do not blend other specific fuel additives with die-
sel fuel. They only result in unnecessary cost, and
may be harmful to the engine operation.
POWER STEERING FLUID
No fluid service required. Filled with Power Steer-
ing Fluid approved to MB 236.3, such as Mobil
ATF-D (Exxon Mobil Corporation) or equivalent.
OPERATION - AUTOMATIC TRANSMISSION
FLUID
The automatic transmission fluid is selected based
upon several qualities. The fluid must provide a high
level of protection for the internal components by
providing a lubricating film between adjacent metal
components. The fluid must also be thermally stable
so that it can maintain a consistent viscosity through
a large temperature range. If the viscosity stays con-
stant through the temperature range of operation,
transmission operation and shift feel will remain con-
sistent. Transmission fluid must also be a good con-
ductor of heat. The fluid must absorb heat from the
internal transmission components and transfer that
heat to the transmission case.

POWER STEERING SYSTEM
Power steering fluid capacities are dependent on
engine/chassis options as well as steering gear/cool-
er options. Depending on type and size of internal
cooler, length and inside diameter of cooler lines, or
use of an auxiliary cooler, these capacities may vary.

STANDARD PROCEDURE - HOISTING
Refer to the Owner's Manual for emergency vehicle

WARNING: THE HOISTING AND JACK LIFTING
POINTS PROVIDED ARE FOR A COMPLETE VEHI-
CLE. WHEN A CHASSIS OR DRIVETRAIN COMPO-
NENT IS REMOVED FROM A VEHICLE, THE

HOISTING CONDITIONS UNSTABLE. PROPERLY
SUPPORT OR SECURE VEHICLE TO HOISTING
DEVICE WHEN THESE CONDITIONS EXIST.
FLOOR JACK
When properly positioned, a floor jack can be used
to lift a vehicle. Support the vehicle in the raised
position with jack stands at the front and rear ends
of the frame rails.
CAUTION: Do not lift vehicle with a floor jack posi-
tioned under:
²An axle tube.
²A body side sill.
²A steering linkage component.
²A drive shaft.
²The engine or transmission oil pan.
²The fuel tank.
²A front suspension arm.
