COMBINATION FLASHER WITH / WITHOUT
DAYTIME RUNNING LAMPS MODULEÐCIRCUIT
DIAGNOSTICS
The battery input (Pin 1), is brought into the Junction
Block through the Electrical Distribution Wiring (EDW)
harness (Fig. 4). It originates under the hood in thePower Distribution Center (PDC) through a 20 ampere
fuse at position 10 (9th position from the upper end) and
labeled HAZARD. This circuit (L09) is the only power
feed to the combination-flasher/DRL.
The ignition input of Pin 6 (refer to Junction Block
Terminal Call-Out and Junction Block Terminal Call-Out
with DRL tables) only senses that the ignition circuit is
ON and does not supply current to the module in a way
that would power the system. This RUN/START circuit is
brought into the junction block to a 10 ampere fuse
labeled TS BU LMP at the bottom right side. The circuit
designation out of the fuse is A22D. This circuit feeds the
combo-flasher and the following systems with Ignition
voltage if the vehicle is so equipped:
²Back-Up Lamps
²Electrochromic Inside Rear view Mirror
²A/C Control Head
²Mini-Trip Computer
²ABS Module
²Front Blower Relay Coil
²Rear Blower Relay Coil
²AWD Solenoids
²Rear Window Defogger (EBL) Relay Coil
The ignition input to the combo-flasher will draw
typically 5 mA of current while active.
For diagnostic test procedures, refer to Combina-
tion Flasher Diagnosis tables.

GENERAL INFORMATION
GENERAL INFORMATION
NS vehicles use lighting on the interior and exte-
rior of the vehicle for illuminating and indicating
purposes. Lighting circuits are protected by fuses.
Lighting circuits require an overload protected power
source, on/off device, lamps and body ground to oper-
ate properly. Plastic lamps require a wire in the har-
ness to supply body ground to the lamp socket.
Replace sockets and bulbs that are corroded.
Some of the interior and exterior lighting functions
are governed by the body controller. The headlamp,
dome, and the door ajar switches provide signals to
the body controller. The body controller in turn acti-
vates relay(s) in order to provide either a ground or
feed line to the appropriate lamp(s).
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male ter-
minals should not be bent or disengaged from the
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be
replaced to avoid recurrence of the problem symp-
toms.
Begin electrical system failure diagnosis by testing
related fuses in the fuse block and power distribution
center. Verify that bulbs are in good condition andtest continuity of the circuit ground. Refer to Group
8W, Wiring Diagrams, for component location and cir-
cuit information.SAFETY PRECAUTIONS
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PER-
SONAL INJURY CAN RESULT.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result.
Do not use bulbs with higher candle power than
indicated in the Bulb Application table at the end of
this group. Damage to lamp and/or Daytime Run-
ning Lamp Module can result.
Do not use fuses, circuit breakers or relays hav-
ing greater amperage value than indicated on the
fuse panel or in the Owners Manual.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.
