(1) Unplug the washer fluid level sensor wire har-
ness connector on the washer reservoir bottle. Check
for continuity between the ground circuit cavity of
the wire harness connector and a good ground. There
should be continuity. If OK, go to Step 2. If not OK,
repair the open circuit as required.
(2) With the washer fluid at the proper level,
check the resistance between the two terminals of
the washer fluid level sensor. The resistance should
be 3000 to 3500 ohms. If OK, go to Step 3. If not OK,
replace the faulty sensor.
(3) Disconnect and isolate the battery negative
cable. Remove the VIC module as described in this
group. Unplug the VIC module wire harness connec-
tor. Check for continuity between the washer fluid
level sense circuit cavity of the VIC module wire har-
ness connector and a good ground. There should be
no continuity. If OK, go to Step 4. If not OK, repair
the short circuit as required.
(4) Check for continuity between the washer fluid
level sense circuit cavities of the VIC module wire
harness connector and the washer fluid level sensor
wire harness connector. If OK, replace the faulty VIC
module. If not OK, repair the open circuit as
required.

WAIT-TO-START LAMP

The diagnosis found here addresses an inoperative
wait-to-start lamp condition. If lamp accuracy is sus-
OR
pect, diagnosis should be performed with a DRB scan
tool as described in the proper Powertrain Diagnostic
Procedures manual. For circuit descriptions and dia-
grams, refer to 8W-40 - Instrument Cluster in Group
8W - Wiring Diagrams.

If the wait-to-start lamp fails to light during the
bulb test (about four seconds after the ignition switch
is turned to the On position), replace the wait-to-
start lamp bulb with a known good unit. If the 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 tool as
described in the proper Body Diagnostic Procedures
manual. Diagnosis of the Powertrain Control Module
(PCM) should be performed with a DRB scan tool as
described in the proper Powertrain Diagnostic Proce-
dures manual.

WATER-IN-FUEL LAMP

The diagnosis found here addresses an inoperative
water-in-fuel lamp condition. If the lamp comes on
and stays on with the ignition switch in the On posi-
tion or while driving, be certain to check for excess
