Test 44A - Repairing Faulty Washer Fluid Level Circuit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Check washer fluid level. If washer fluid is not full, add fluid as necessary. If washer fluid is full, read washer fluid switch status using DRB-II. If DRB-II displays CIRCUIT OPEN, go to step 4). If DRB-II does not display CIRCUIT OPEN, disconnect washer fluid level switch connector.
  2. If DRB-II displays CIRCUIT OPEN, replace washer fluid level switch. If DRB-II does not display CIRCUIT OPEN, turn ignition switch to OFF position. Disconnect Natural body controller connector. Body controller is located under left side of instrument panel.
  3. Check connector, and clean or repair connector as necessary. Using DRB-II in ohmmeter mode, check resistance of washer fluid level sense circuit at Natural body controller connector terminal No. 13 (Black/Tan wire). If resistance is less than 5 ohms, repair short to ground in Black/Tan wire. If resistance is more than 5 ohms, replace body controller.
  4. Disconnect washer fluid level switch connector. Connect a jumper wire between Black/Tan and Black wires of washer fluid level switch connector. If DRB-II displays CIRCUIT CLOSED, replace washer fluid level switch. If DRB-II does not display CIRCUIT CLOSED, disconnect jumper wire.
  5. Connect a jumper wire between washer fluid level sense circuit (Black/Tan wire) at washer fluid level switch connector and ground. If DRB-II displays CIRCUIT CLOSED, repair open in Black wire. If DRB-II does not display CIRCUIT CLOSED, gain access to body controller.
  6. Body controller is located under left side of instrument panel. Connect a jumper wire between washer fluid level sense circuit at Natural body controller connector terminal No. 13 (Black/Tan wire) and ground. If DRB-II displays CIRCUIT CLOSED, repair open in Black/Tan wire. If DRB-II does not display CIRCUIT CLOSED, replace body controller.
