Test 34A - Washer Pump Operation
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see WIRING DIAGRAMS
. Perform TEST VER-1 after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector.
- Ensure washer fluid reservoir is full. Check windshield washer pump operation. If washer pump does not operate, go to step 3). If washer pump operates, turn ignition switch to OFF position. Disconnect Body Control Module (BCM) Bone connector. BCM is located behind right kick panel. Go to next step.CAUTION: DO NOT keep washer button pressed longer than necessary to test for voltage. Damage to washer pump may occur.
- Turn ignition switch to ON position. Using DRB in voltmeter mode, while pressing windshield washer button on end of wiper/washer stalk, check voltage on BCM Bone connector terminal No. 10 (Brown wire). If voltage is less than 10 volts, repair open Brown wire between BCM and switch. If voltage is more than 10 volts, replace BCM.
- If wipers operate in step 1), go to TEST 34B. If wipers do not operate, turn ignition switch to OFF position. Disconnect Body Control Module (BCM) Bone connector and multifunction switch connector. BCM is located behind right kick panel. Multifunction switch connector is located on upper part of steering column, behind trim cover. Go to next step.
- Using an external ohmmeter, check resistance of Brown wire between BCM Bone connector terminal No. 10 and multifunction switch connector terminal No. 2. If resistance is more than 5 ohms, repair open Brown wire. If resistance is less than 5 ohms, replace multifunction switch.
