Washers
When the GEM detects the ignition switch circuits are in RUN or ACC states, and the GEM detects a
WASH request from the wiper delay/wash circuits, the GEM will activate the washer pump relay circuit
for as long as the request is present up to 10 seconds.
Activation of the washer pump when in INTERVAL or OFF is delayed until a wash request is active for
a minimum amount of time. In this scenario, the wash request must be present continuously for at least
210 ms. This allows a wash request that is present for less than 210 ms, to provide additional
functionality by initiating a single wipe, called "mist wipe". The mist wipe function is a single wipe at low
speed without activating the washer motor.
When in LOW or HIGH, any WASH request, regardless of the length of time it is present, will activate
the washer pump. When in INTERVAL or OFF mode, upon deactivation of the washer motor, this
feature shall provide two wipes at low speed before returning to the INTERVAL or OFF state as
defined by the inputs. These additional wipes are provided to clear residual washer fluid from the front
windshield.
Inspection and Verification
1. Verify the customer concern by operating the wiper/washer system.
2. Visually inspect for obvious signs of mechanical and electrical damage.
3. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the
diagnostic tool menu. If diagnostic tool does not communicate with the vehicle:
zCheck that the program card is correctly installed.
z Check the connections to the vehicle.
z Check the ignition switch position.
4. If diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If diagnostic tool responds with: zCKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418 -
00 .
z NO RESPONSE/NOT EQUIPPED for GEM, go to Pinpoint Test A.
z SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs),
erase the continuous DTCs and carry out self- test diagnostics for the GEM.
