WIRING DIAGRAM
INFORMATION
DESCRIPTION - HOW TO USE WIRING
DIAGRAMS
DaimlerChrysler Corporation wiring diagrams are
designed to provide information regarding the vehi-
cles wiring content. In order to effectively use the
wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important
to understand all of their features and characteris-
tics.
Diagrams are arranged such that the power (B+)
side of the circuit is placed near the top of the page,
and the ground (B-) side of the circuit is placed near
the bottom of the page (Fig. 1).
All switches, components, and modules are shown
in the at rest position with the doors closed and the
key removed from the ignition (Fig. 2).Components are shown two ways. A solid line
around a component indicates that the component is
complete. A dashed line around the component indi-
cates that the component is being shown is not com-
plete. Incomplete components have a reference
number to indicate the page where the component is
shown complete.
It is important to realize that no attempt is made
on the diagrams to represent components and wiring
as they appear on the vehicle. For example, a short
piece of wire is treated the same as a long one. In
addition, switches and other components are shown
as simply as possible, with regard to function only.
SYMBOLS
International symbols are used throughout the wir-
ing diagrams. These symbols are consistent with
those being used around the world (Fig. 3).

(4) If the voltmeter registers voltage or the test
lamp glows, there is a short to ground in that gen-
eral area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR
SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
(1) Refer to the wiring diagrams and disconnect or
isolate all items on the suspected fused circuits.
(2) Replace the blown fuse.
(3) Supply power to the fuse by turning ON the
ignition switch or re-connecting the battery.
(4) Start connecting the items in the fuse circuit
one at a time. When the fuse blows the circuit with
the short to ground has been isolated.
STANDARD PROCEDURE - TESTING FOR A
VOLTAGE DROP
(1) Connect the positive lead of the voltmeter to
the side of the circuit closest to the battery (Fig. 7).
(2) Connect the other lead of the voltmeter to the
other side of the switch or component.
(3) Operate the item.
(4) The voltmeter will show the difference in volt-
age between the two points.

v

When testing voltage or continuity at any control
module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the
insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as
to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a
second DTC could be set, making diagnosis of the
original problem more difficult.

GENERAL INFORMATION

TEST ACTION APPLICABILITY
3WARNING: 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.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRB
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DRB Freeze Frame information. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.

TEST ACTION APPLICABILITY
1Note: The following list of items must be checked before continuing with
any no start tests.
The battery must be fully charged and in good condition. A low charged battery may
produce invalid test results. If the battery is low, charge the battery and then attempt
to start the vehicle by cranking the engine for 15 seconds, 3 consecutive times.
This will allow any DTC's to set that may have been erased due to a dead battery.
Ensure the Powers and Ground to the PCM are ok.
Make sure the PCM communicates with the DRB and that there are no DTC's stored
in the PCM memory. If the PCM reports a No Response condition, refer to the
Communication category for the proper tests.
Read the PCM DTC's with the DRB. If any DTC's are present, they must be repaired
before continuing with any other No Start diagnostic tests. Refer to the Symptom list
for the related P-code that is reported by the PCM.
Ensure that the PCI bus is functional. Attempt to communicate with the Instrument
Cluster and SKIM, If you are unable to establish communicate refer to the
Communication category for the proper symptoms.
The Sentry Key Immobilizer System must be operating properly. Check for proper
communication with the DRB and check for DTC's that may be stored in the Sentry
Key Immobilizer Module (SKIM). repair the DTC(s) before continuing.
If no DTC's are found, using the DRB select Clear PCM (Batt Disconnect).
Crank the engine several times. Using the DRB, read DTC's. If a DTC is present
perform the DTC diagnostics before continuing.
Were any problems found?All

Caution: Stop All Actuations.
4 Turn the ignition off.
WARNING: The fuel system is under a constant pressure even with the
engine off. Before testing or servicing any fuel system hose, fitting or line,
the fuel system pressure must be released.
Install a fuel pressure gauge to the fuel rail test port.
Turn the ignition on.
With the DRBIIIt, actuate the ASD Fuel System test and observe the fuel pressure
gauge.
NOTE: Fuel pressure specification is 400 kPa +/- 34 kPa (58 psi +/- 5 psi).
Choose a conclusion that best matches your fuel pressure reading.All
