ADJUSTING METHOD FOR JAM PROTECTION
Note. Use this procedure when power window motor has been replaced or when power window motor has been run while removed from vehicle.
To adjust limit switch to OFF position, connect motor to harness connector and operate power window motor in UP direction for 4-5 seconds. This sets limit switch to full UP position (OFF).
WINDOW REVERSES WHEN OPERATED IN AUTO UP MODE (DRIVER'S WINDOW ONLY)
If window reverses when window is being raised in AUTO UP mode, check door glass run, window regulator, window motor or window guide for sign of damage or misalignment. Resistance in window glass movement causes window to reverse direction. Check power window motor limit switch for proper adjustment. See ADJUSTING METHOD FOR JAM PROTECTION under ADJUSTMENTS. If all mechanical checks are okay, replace driver's power window master switch with a known-good unit and retest.
AUTO REVERSE INOPERATIVE WITH OBSTRUCTION IN WINDOW
Note. This test diagnoses inoperative AUTO REVERSE operation (jam function) when foreign object restricts window up operation. AUTO REVERSE mode will not operate when window is within .157" (4 mm) of fully open position.
- Ensure all power window modes function normally (i.e., UP, DOWN, AUTO UP, AUTO DOWN and key OFF). If all modes function normally, go to next step. If all modes do not function normally, perform appropriate symptom test.
- AUTO REVERSE should operate when there is resistance to power window motor while raising window. If window opening is greater than 7.874" (200 mm) when window glass travel is obstructed, window will automatically lower 1.969" (50 mm) and stop. If window opening is 7.874" (200 mm) or less when window glass travel is obstructed, window will automatically lower until opening is 7.874" (200 mm) and stop. If operation is as specified, system is okay at this time. If operation is not as specified, go to next step.
- Check power window motor limit switches for proper adjustment. See «ADJUSTING METHOD FOR JAM PROTECTION»(ref-5106-S33347473212000080300000) under ADJUSTMENTS. Ensure power window motor is installed correctly. If motor is installed correctly and AUTO REVERSE still does not operate as specified, replace power window master switch or power window control switch.
ONE-TOUCH POWER WINDOW IS INOPERATIVE
Note. When a fault for one-touch mode in driver's power window master switch occurs, AUTO light on power window master switch will output a flash code. After 30 seconds, AUTO light will stop flashing and will stay on. If ignition switch is turned to OFF position during flash mode, flashing will stop.
Scheme 10
- Turn ignition switch to ON position and toggle power window master switch to UP or DOWN position for driver's side window only. Ensure power window master switch AUTO light begins to flash fault code. (Scheme 10) For Fault Code 1, go to next step. For Fault Code 2 or 3, go to step 3. If AUTO light does not stay illuminated after 30 seconds, or flashes stop after ignition switch is turned to OFF position, replace power window master switch.
- Fault Code 1 occurs when there is an error in power window motor limit switch. Remove power window master switch from door panel, with connector attached. Measure voltage by backprobing between power window master switch connector terminals No. 1 and 5. Voltage should change from zero volts when window is fully closed, to 10-14 volts while window is opening. If voltage is not as specified, go to next step. If voltage is as specified, replace power window master switch. If AUTO UP and AUTO DOWN does not work after power window master switch is replaced, replace power window motor.
- Disconnect power window master switch and driver's power window motor from harness connectors. Check continuity between appropriate power window master switch terminals and driver's power window motor terminals. See «ONE-TOUCH POWER WINDOW TESTS»(ref-5106-S00160914782000080300000) table. If continuity is present at all measurements, go to next step. If continuity is not present at any measurement, repair open circuit in affected wire.
