Test M: Low Washer Indicator Never/Always On

  1. Turn ignition switch to LOCK position. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located below left side of instrument panel, to right of steering column. Turn ignition switch to RUN position. Using NGS tester, select instrument cluster active command WARNING LAMPS AND CHIMES. Trigger ALL LAMPS to ON, then OFF. Low washer display should illuminate when triggered ON and should not illuminate when triggered OFF. If low washer display operates as specified, go to next step. If low washer display does not operate as specified, replace instrument cluster.
  2. Turn ignition switch to LOCK position. Disconnect washer fluid level switch harness connector C138. Turn ignition switch to RUN position. Using NGS tester, monitor Front Electronic Module (FEM) PID WFLUID. Using a fused jumper wire, ground washer fluid level switch harness connector terminal No. 2 (White/Blue wire). With jumper wire connected, PID should display ON. Without jumper wire connected, PID should display OFF. If PID displays as specified, go to next step. If PID does not display as specified and jumper wire fuse blows, go to step  5 . If PID does not display as specified and jumper wire fuse does not blow, exit PID and go to step  4 .
  3. Turn ignition switch to LOCK position. Measure resistance between ground and washer fluid level switch harness connector C138 terminal No. 1 (Black/Orange wire). If resistance is 5 ohms or less, replace washer fluid level switch. If resistance is more than 5 ohms, repair open in Black/Orange wire between ground and washer fluid level switch. Ground point is located, at right front of engine compartment, ahead of fenderwell.
  4. Turn ignition switch to LOCK position. Disconnect FEM 22-pin harness connector C201b. FEM is located behind driver's side kick panel. See Figure . Measure resistance between ground and washer fluid level switch harness connector terminal No. 2 (White/Blue wire). If resistance is more than 10 k/ohms, replace FEM. If resistance is 10 k/ohms or less, repair short to ground in White/Blue wire between washer fluid level switch and FEM.
  5. Turn ignition switch to LOCK position. Disconnect FEM 22-pin harness connector C201b. FEM is located behind driver's side kick panel. See Figure . Turn ignition switch to RUN position. Measure voltage between ground and FEM harness connector C201b terminal No. 15 (White/Blue wire). See Figure . If voltage does not exist, replace FEM. If voltage exists, repair short to voltage in White/Blue wire between washer fluid level switch and FEM.
