DODGE NEON 1999 Service Repair Manual

NO FASTEN SEAT BELT LAMP WHEN
IGNITION SWITCH IS ON.
(1) Check for burned out lamp.
(2) Check for battery feed at cluster wire harness
connector terminal J1-6 (Fig. 1).
(3) Check for ignition feed at cluster wire harness
connector terminal J1-5. Repair as necessary.
NO TONE WHEN HEADLAMPS ARE ON AND
DRIVERS DOOR IS OPEN
(1) Check left door jamb switch for good ground
when drivers door is open.
(2) Check for ground at J2-5.
(3) Check for battery feed at cluster wire harness
connector terminal J1-6 (Fig. 1).
(4) Check for NO voltage at J1-5. Ignition voltage
must not be present for the chime to work.
(5) Check headlamp switch.
NO TONE WHEN KEY IS LEFT IN IGNITION
AND DRIVERS DOOR IS OPEN
(1) Check for continuity to ground at Pin 8 of the
J1 wire harness connector. If OK, go to Step 3. If not
OK, repair as necessary.(2) Using voltmeter, check for battery feed at Pin 6
of the J1 wire harness connector. Check for NO igni-
tion feed at Pin 5 of the J1 wire harness connector. If
OK, go to Step 3. If not OK, repair as necessary.
(3) Open driver's door and ensure the ignition key
is in the OFF or ACC position. Check for continuity
to ground at Pin 5 of the J2 wire harness connector.
If ground OK, replace cluster printed circuit board. If
no ground, check key-in switch or door switch wiring
and repair as necessary.
CHIMES CONTINUE WHEN HEADLAMPS ARE
TURNED OFF AND/OR KEY IS REMOVED
FROM IGNITION
Check for ground at J2-5. If grounded the chime
should activate. Make sure the door is closed, key is
in ignition and parking lamps are OFF. If ground is
still present check door switch, key in switch, head-
lamp switch and repair as necessary.
REMOVAL AND INSTALLATION
CHIME
The chime is built into the instrument cluster print
circuit board. Refer to Group 8E, Instrument Panel
and Gauges.
SEAT BELT BUCKLE
Refer to Group 23, Body of this service manual.
HEADLAMP SWITCH
Refer to Group 8E, Instrument Panel and Systems.
KEY-IN SWITCH
The Key-in switch is built into the ignition switch
assembly. Should the Key-in switch require service,
the ignition switch assembly must be replaced. Refer
to Group 8D Ignition System of this service manual.

DESCRIPTION AND OPERATION
INTRODUCTION
Chrysler wiring diagrams are designed to provide
information regarding the vehicles wiring content. In
order to effectively use Chrysler wiring diagrams to
diagnose and repair a Chrysler vehicle, it is impor-
tant to understand all of their features and charac-
teristics.
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.
All switches, components, and modules are shown
in the at rest position with the doors closed and the
key removed from the ignition.Components are shown two ways. A solid line
around a component indicates that the component is
complete. A dashed line around a component indi-
cates that the component 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.

CIRCUIT INFORMATION
Each wire shown in the diagrams contains a code
which identifies the main circuit, part of the main
circuit, gage of wire, and color (Fig. 1)
CIRCUIT FUNCTIONS
All circuits in the diagrams use an alpha/numeric
code to identify the wire and its function. To identify
which circuit code applies to a system, refer to the
Circuit Identification Code Chart. This chart shows
the main circuits only and does not show the second-
ary codes that may apply to some models.

SECTION IDENTIFICATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
SYMBOLS
International symbols are used throughout the wir-
ing diagrams. These symbols are consistent with
those being used around the world.

CONNECTOR INFORMATION
CAUTION: Not all connectors are serviced. Some
connectors are serviced only with a harness. A typ-
ical example might be the Supplemental Restraint
System connectors. Always check parts availability
before attempting a repair.
IDENTIFICATION
In-line connectors are identified by a number, as
follows:
²In-line connectors located on theengine com-
partment harnessareC100series numbers.
²Connectors located on theinstrument panel
harnessareC200series numbers.
²Connectors located on thebody harnessare
C300series numbers.
²Jumper harness connectorsareC400series
numbers.
²Grounds and ground connectorsare identi-
fied with aªGºand follow the same series number-
ing as the in-line connector.
Component connectors are identified by the compo-
nent name instead of a number (Fig. 2). Multiple
connectors on a component use a C1, C2, etc. identi-
fier (Fig. 3).
LOCATIONS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector
name (or number)/ground number and component
identification. Connector/ground location charts in
Section 8W-90 reference the illustration number for
components and connectors.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the Dia-
gram pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.
NOTES, CAUTIONS, and WARNINGS
Throughout this group additional important infor-
mation is presented in three ways; Notes, Cautions,
and Warnings.
NOTESare used to help describe how switches or
components operate to complete a particular circuit.
They are also used to indicate different conditions
that may appear on the vehicle. For example, an
up-to and after condition.
CAUTIONSare used to indicate information that
could prevent making an error that may damage the
vehicle.
WARNINGSprovide information to prevent per-
sonal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a
vehicle is being serviced.
WARNING: ALWAYS WEAR SAFETY GLASSES FOR
EYE PROTECTION.
WARNING: USE SAFETY STANDS ANYTIME A PRO-
CEDURE REQUIRES BEING UNDER A VEHICLE.
