Test D: One-Touch Down Feature Does Not Operate
- Check Driver Door Master Window Switch - Turn ignition off. Remove and disconnect driver door master window switch. Turn ignition switch to RUN position. Connect a jumper wire between driver door master window switch 16-pin connector C74a terminal No. 9 (White wire) and driver door master window switch 4-pin connector C74b terminal No. 3 (Black wire). See Figure and Figure . Connect another jumper wire between driver door master window switch 16-pin connector C74a terminal No. 12 (Gray/Orange wire), master window switch 16-pin connector C74a terminal No. 11 (White/Green wire), and driver door master window switch 4-pin connector C74b terminal No. 2 (Violet/Blue wire). If one-touch window down does not operate, go to next step. If one-touch window down operates, replace driver door master window switch and retest system operation.
- Check Gray/Orange Wire For Open Or Short To Ground - Turn ignition off. Remove one-touch window down relay (located in driver's door). Using an ohmmeter, check resistance between driver door master window switch connector C74a terminal No. 12 (Gray/Orange wire) and one-touch window down relay connector terminal No. 4 (Gray/Orange wire). See Figure and Figure . Check resistance between ground and driver door master window switch connector C74a terminal No. 12 (Gray/Orange wire). If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, go to next step. If resistance is 5 ohms or more between connectors and 10 k/ohms or less between connector and ground, repair Gray/Orange wire and retest system operation.
- Check Violet/Orange Wire For Voltage - Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and one-touch window down relay connector terminal No. 2 (Violet/Orange wire). See Figure . If reading is more than 10 volts, go to next step. If reading is 10 volts or less, repair Violet/Orange wire and retest system operation.
- Check Black Wire For Open - Using an ohmmeter, check resistance between ground and one-touch window down relay connector terminal No. 1 (Black wire). If resistance is less than 5 ohms, replace one-touch window down relay and retest system operation. If resistance is 5 ohms or more, repair open in Black wire and retest system operation.
