  3. Ensure ignition switch is in ON position. Using DRB in voltmeter mode, check voltage on message center connector terminal No. 4 (Dark Blue/White wire). If voltage is less than 10 volts, repair open Dark Blue/White wire. If voltage is more than 10 volts, go to next step.
  4. Reinstall low washer fluid lamp. Reconnect message center connector. Connect jumper wire between message center connector terminal No. 6 (Red wire) and ground. If low washer fluid lamp does not illuminate, replace message center. If low washer fluid lamp illuminates, go to next step.

  7. Using DRB, read washer fluid switch status. If DRB displays WASH FLUID LOW, replace washer fluid level switch. If DRB does not display WASH FLUID LOW, disconnect jumper wire. Go to next step.
  8. Connect jumper wire between washer fluid level connector terminal No. 2 (Black/Tan wire) and ground. If DRB displays WASH FLUID LOW, repair open Black/Tan wire. If DRB does not display WASH FLUID LOW, go to next step.
  9. Gain access to Body Control Module (BCM). BCM is located behind right kick panel. Leave BCM connectors connected. Connect jumper wire between BCM Gray connector terminal No. 17 (Black/Tan wire) and ground. If DRB displays WASH FLUID LOW, repair open Black/Tan wire. If DRB does not display WASH FLUID LOW, replace BCM.
