Pinpoint Test F - Memory Mirrors Cannot Be Programmed
- Memory Mirror System Voltage Check - Partially remove memory mirror module. Using test light, backprobe Orange wire terminal of memory mirror module Black connector. See Figure . If test light comes on, go to next step. If test light does not come on, repair open Orange wire. Retest system.
- Ignition Input Check At Module - Turn ignition on. Using test light, backprobe Red/Light Blue wire terminal of memory mirror module Gray connector. See Figure . If test light comes on, go to next step. If test light does not come on, repair open Red/Light Blue wire. Retest system.
- Circuit Check At Memory Mirror Module - Check resistance between Black wire terminal of memory mirror module Black connector and ground. See Figure . If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open Black wire. Retest system.
- Input Check At Module - Check voltage at White/Orange wire terminal of memory mirror module Gray connector. See Figure . If voltage is 10 volts or greater, go to next step. If voltage is less than 10 volts, repair open White/Orange wire. Retest system.
- Memory Switch Input To Module Test - Connect voltmeter to Brown/Light Green wire terminal of memory mirror module Gray connector. See Figure . At driver's door front trim panel, press set button of memory seat regulator control. Within 5 seconds, press button No. 1 and read voltage. If voltage is 10 volts or greater, go to next step. If voltage is less than 10 volts, replace memory mirror module and retest system.
- Memory Switch Input Circuits Check - Turn ignition off. Unplug memory mirror module Gray connector. See Figure . Remove left memory seat regulator control. Check continuity of Brown/Light Green wire and Black/Orange wire between memory switch connector and 16-pin connector (Gray). If resistance is 5 ohms or less, replace mirror memory seat regulator control. Retest system. If resistance is greater than 5 ohms, repair open Brown/Light Green wire and/or Black/Orange wire. Retest system.
