TURN SIGNAL INDICATOR LAMP
The turn signal indicator lamps are located in the
instrument cluster. They flash with the exterior turn
signal lamps to give the driver a visual indication
that a turn signal or the hazard warning system is
operating. For diagnosis and service of these lamps,
refer to Group 8E - Instrument Panel Systems.
VEHICLE INFORMATION CENTER
Models equipped with the optional Vehicle Infor-
mation Center (VIC) have a “turn signal on” warning
feature. The VIC module monitors the turn signal
circuit through the combination flasher. The VIC
module will display a Turn Signal On message and
send a request to the Body Control Module (BCM) on
the Chrysler Collision Detection (CCD) data bus net-
work for six chime tones, if a turn signal remains
activated for more than approximately one-half mile
of driving.
Refer to Group 8E - Instrument Panel Systems for
more information on the VIC module. For diagnosis
of the VIC, the BCM or the CCD data bus, the use of
a DRB scan tool and the proper Diagnostic Proce-
dures manual are recommended.
TURN SIGNAL LAMP
The exterior lamps in the turn signal and hazard
warning circuits include the front park/turn signal,
the front side marker, and the rear tail/stop/turn sig-
nal. For diagnosis and service of these lamps, refer to
Group 8L - Lamps.
DIAGNOSIS AND TESTING
INTRODUCTION
When diagnosing the turn signal or hazard warn-
ing circuits, remember that high generator output
can burn out bulbs rapidly and repeatedly. If this is a
problem on the vehicle being diagnosed, refer to
Group 8C - Charging System for further diagnosis of
a possible generator overcharging condition.

(1) Turn the ignition switch to the On position.
Actuate the turn signal lever or the hazard warning
button. Observe the turn signal indicator lamp(s) in
the instrument cluster. If the flash rate is very high,
check for a turn signal bulb that is not lit or is very
dimly lit. Repair the circuits to that lamp or replace
the faulty bulb, as required. Test the operation of the
turn signal and hazard warning systems again. If the
turn signal indicator(s) fail to light, go to Step 2.
(2) Turn the ignition switch to the Off position.
Check the turn signal fuse in the junction block
and/or the hazard warning fuse in the Power Distri-
bution Center (PDC). If OK, go to Step 3. If not OK,
repair the shorted circuit or component as required
and replace the faulty fuse(s).
