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.

WARNING: BEFORE SERVICING A STEERING COL-
UMN EQUIPPED WITH AN AIRBAG REFER TO
GROUP 8M, RESTRAINT SYSTEMS FOR PROPER
AND SAFE SERVICE PROCEDURES.
REMOVAL
(1) Release hood latch and open hood.
(2) Disconnect and isolate battery negative cable.
(3) Remove upper and lower steering column
shrouds, refer to Group 19, Steering for proper pro-
cedures.
(4) Disconnect wire connector from back of turn
signal multi-function switch (Fig. 6).
(5) Remove screws holding turn signal switch to
steering column adapter collar.
(6) Remove turn signal switch.
INSTALLATION
