  5. Using DRB in ohmmeter mode, check resistance of washer fluid level sense circuit (Black/Tan wire) at Natural BCM connector terminal No. 13. If resistance is less than 5 ohms, repair short to ground in Black/Tan wire. Perform TEST VER-1B. If resistance is more than 5 ohms, replace BCM. Perform TEST VER-1B.
  6. Disconnect washer fluid level switch connector. Connect a jumper wire between Black/Tan and Black wires of washer fluid level switch connector. If DRB displays CIRCUIT CLOSED, replace washer fluid level switch. Perform TEST VER-1B. If DRB does not display CIRCUIT CLOSED, go to next step.
  7. Disconnect jumper wire. Connect a jumper wire between washer fluid level sense circuit (Black/Tan wire) at washer fluid level switch connector and ground. If DRB displays CIRCUIT CLOSED, repair open in Black wire. Perform TEST VER-1B. If DRB does not display CIRCUIT CLOSED, go to next step.
  8. Gain access to BCM. BCM is located behind center console. Connect a jumper wire between washer fluid level sense circuit (Black/Tan wire) at BCM connector terminal No. 13 and ground. If DRB displays CIRCUIT CLOSED, repair open in Black/Tan wire. Perform TEST VER-1B. If DRB does not display CIRCUIT CLOSED, replace BCM. Perform TEST VER-1B.
