Windshield Wiper Test 3B - Wipers Not Working In Intermittent Mode
NOTE:
Perform WINDSHIELD WIPER TEST 3A
before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Using scan tool, monitor intermittent wiper voltage level. Rotate wiper switch from low intermittent to high intermittent level. If voltage changes from approximately 2.5 to 12 volts, replace CTM. If voltage does not change from approximately 2.5 to 12 volts, go to next step.
- Disconnect 24-pin multifunction switch connector. Using an external ohmmeter, measure resistance of White wire between multifunction switch connector terminal No. 1 and CTM 14-pin Green connector "A" terminal No. 12. if resistance is less than 5 ohms, replace multifunction switch. If resistance is 5 ohms or more, repair open White wire between multifunction switch and CTM.
