Test S: Power Sliding Door On/Off Switch Open Circuit

  1. Turn ignition switch to RUN position. Ensure power sliding door is completely closed and latched. Press overhead console on/off switch to ON position. Using New Generation Star (NGS) tester, perform Left Power Siding Door Module (LPSDM) or Right Power Siding Door Module (RPSDM) self-tests. If DTC B2604 is retrieved, go to next step. If DTC B2604 is not retrieved, conditions were not correct for self-test. Repair any remaining DTCs. See LEFT POWER SLIDING DOOR MODULE DTC INDEX  or RIGHT POWER SLIDING DOOR MODULE DTC INDEX  table under SELF-DIAGNOSTIC SYSTEM.
  2. Using NGS tester, perform RPSDM self-test. If DTC B2604 is not retrieved, go to next step. If DTC B2604 is retrieved, go to step  4.
  3. Disconnect overhead console switch 8-pin harness connector C915 and LPSDM 12-pin harness connector C355. Measure resistance of Violet/White wire between LPSDM harness connector C355 terminal No. 6 and overhead console switch harness connector C915 terminal No. 4. If resistance is less than 5 ohms, clear LPSDM DTCs and repeat LPSDM self-test. If DTC B2604 is retrieved, replace LPSDM. If resistance is 5 ohms or more, repair open in Violet/White wire.
  4. Open and close right power sliding door from overhead console open/close switch. If door does not operate correctly, go to next step. If door operates correctly, go to step  6.
  5. Disconnect overhead console switch 8-pin harness connector C915. Measure resistance between overhead console switch harness connector C915 terminal No. 6 (Black wire) and ground. If resistance is less than 5 ohms, replace overhead console switch assembly. If resistance is 5 ohms or more, repair open to in Black wire.
  6. Turn ignition switch to RUN position. Measure voltage between overhead console switch harness connector C915 terminal No. 4 (Violet/White wire) and ground. If reading is 10 volts or less, go to next step. If reading is more than 10 volts, repair short to voltage in Violet/White wire.
  7. Disconnect overhead console switch 8-pin harness connector C915 and RPSDM 12-pin harness connector C352. Measure resistance of Violet/White wire between RPSDM harness connector C352 terminal No. 6 and overhead console switch harness connector C915 terminal No. 4. If resistance is less than 5 ohms, clear RPSDM DTCs and repeat RPSDM self-test. If DTC B2604 is retrieved, replace RPSDM. If resistance is 5 ohms or more, repair open in Violet/White wire.
