Test 26C - Wiper Switch Mode Sense Circuit

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.
  1. Stop wiper motor actuation test. Using DRB, read intermittent wiper sensor status. Observe DRB while gradually moving wiper switch from off to high position. If DRB displays INTRMT WIPE 0V (zero volts) or more, replace Body Control Module (BCM). If DRB does not display INTRMT WIPE 0V (zero volts) or more, go to next step.
  2. Disconnect multifunction switch connector. Connector is located on upper part of steering column, behind trim cover. Using DRB in voltmeter mode, check voltage on multifunction switch connector terminal No. 3 (Dark Blue wire). If voltage is less than 10 volts, repair open Dark Blue wire between switch and fuse No. 10. If voltage is more than 10 volts, go to next step.
  3. Disconnect BCM Bone connector. BCM is located behind right kick panel. Using DRB in ohmmeter mode, check resistance of BCM Bone connector terminal No. 16 (Dark Green/Red wire). If resistance is less than 5 ohms, repair short to ground in Dark Green/Red wire. If resistance is more than 5 ohms, go to next step.
  4. Using an external ohmmeter, check resistance of Dark Green/Red wire between multifunction switch connector terminal No. 1 and BCM Bone connector terminal No. 16. If resistance is more than 5 ohms, repair open Dark Green/Red wire between switch and BCM. If resistance is less than 5 ohms, go to next step.
  5. Reconnect multifunction switch connector. Turn wiper switch to low or high position. Using DRB in voltmeter mode, backprobe multifunction switch connector terminal No. 16 (Dark Green/Red wire). If voltage is less than 10 volts, replace multifunction switch. If voltage is more than 10 volts, replace BCM.
