Test C: One-Touch Down Feature Inoperative
- Check For Voltage To One-Touch Down Control Unit - Turn ignition off. Disconnect 5-pin one-touch down control unit connector C205 (located behind left side of instrument panel). Using a voltmeter, check voltage between ground and one-touch down control unit 5-pin connector C205 terminal No. 3 (Black/White wire). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair Black/White wire and retest system operation.
- Check One-Touch Down Control Unit Ground Circuit - Using an ohmmeter, check resistance between ground and one-touch down control unit 5-pin connector C205 terminal No. 5 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black wire between one-touch down control unit 5-pin connector and ground. Retest system operation.
- Check Red/Black Wire For Open - Disconnect 15-pin driver door master window switch connector C509. Disconnect 5-pin one-touch down control unit connector C205 (located behind left side of instrument panel). Using an ohmmeter, check resistance in Red/Black wire between driver door master window switch connector C509 terminal No. 13 and one-touch down control unit connector C205 terminal No. 4. If resistance is less than 5 ohms, replace one-touch down control unit and retest system operation. If resistance is 5 ohms or more, repair open in Red/Black wire and retest system operation.
