Pinpoint Test F - Memory Seat Does Not Work Properly
- Voltage Supply To Power Seat Memory Module Check - Using test light, check Black/White wire for voltage at seat memory module connector. If test light comes on, go to next step. If test light does not come on, repair open in Black/White wire. Retest system.
- Ignition Input At Memory Module Check - Turn ignition on. Using test light, check White/Purple wire for voltage at seat memory module connector. If test light comes on, go to next step. If test light does not come on, repair open in White/Purple wire. Retest system.
- Memory Module Ground Circuit Check - Using ohmmeter, check resistance between Black wire at seat memory module connector and ground. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Black wire. Retest system.
- Input Circuit Test (White/Orange Wire) - Using voltmeter, backprobe White/Orange wire at seat memory module connector. Press memory seat switch. If reading is 10 volts or more, go to next step. If reading is less than 10 volts, repair open in White/Orange wire. Retest system.
- Memory Switch To Memory Module Input Test - Using voltmeter, backprobe Brown/Light Green wire at seat memory module connector. Press set button at memory seat switch. Within 5 seconds, press button No. 1 and read voltage. If less than 10 volts exists, go to next step. If 10 volts or more exists, replace power seat motor. Retest system.
- Memory Switch Input Circuit Check - Turn ignition off. Disconnect seat memory module connector. Using ohmmeter, measure resistance of Brown/Light Green wire between memory switch connector and seat memory module connector. Measure resistance of Black/Orange wire between memory switch connector and seat memory module connector. If resistance in both wires is 5 ohms or less, replace memory switch. If resistance in either or both wire(s) is more than 5 ohms, repair open in suspect circuit. Retest system.
