If the water-in-fuel lamp fails to light during the
bulb test (about three seconds after the ignition
switch is turned to the On position), replace the
water-in-fuel lamp bulb with a known good unit. If
the indicator lamp still fails to operate, diagnosis of
the lamp, the instrument cluster circuitry, or the
CCD data bus should be performed with a DRB scan

SERVICE PROCEDURES

VEHICLE INFORMATION CENTER

The following flow charts describe the procedures
to perform an initial setup of the Vehicle Information
Center (VIC), and how to reset the VIC service
OR
reminder or time/date settings.
If the vehicle is equipped with a Chrysler radio
that is connected to the Chrysler Collision Detection
(CCD) data bus network, the hour and minute set-
tings of the VIC clock will automatically be synchro-
nized to the hour and minute settings of the radio
clock. This is done by a message that the radio sends
to the VIC module on the CCD data bus. Also, the
VIC module will automatically suppress the VIC
hour and minute set functions if there is a Chrysler
radio connected to the CCD data bus, and the VIC
clock must be set through the radio clock. Refer to
Group 8F - Audio Systems for more information on
this feature.
