NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagram, see WIRING DIAGRAMS article in this section.
CAUTION: Always turn ignition off prior to disconnecting or connecting any module connector.
  1. Check washer fluid level. If washer fluid is not full, add fluid as necessary. Perform TEST VER-1B  . If washer fluid is full, go to next step.
  2. Using DRB, read washer fluid switch status. If DRB displays CIRCUIT OPEN, go to step 6). If DRB does not display CIRCUIT OPEN, go to next step.
  3. Disconnect washer fluid level switch connector. If DRB displays CIRCUIT OPEN, replace washer fluid level switch. Perform TEST VER-1B  . If DRB does not display CIRCUIT OPEN, go to next step.
  4. Turn ignition off. Disconnect Natural Body Control Module (BCM) connector. BCM is located behind center console. Check connector, and clean or repair connector as necessary. Perform TEST VER-1B  . If connector is okay, go to next step.
  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  .
