Power Window Sub-Switch Check

NOTE: If scan tool is not available, begin testing at step  2 .
  1. Using scan tool, select P/W SW UP or DOWN in DATA MONITOR mode. See SELF-DIAGNOSTIC SYSTEM  . P/W SW UP or DOWN parameter on scan tool display should change from OFF to ON as each sub-switch is pressed. If scan tool display is as specified, power window sub-switch is okay. If scan tool display is not as specified, replace LCU for malfunctioning sub-switch.
  2. Check power window sub-switch operation using on-board diagnostics Mode II (switch signal monitor). See SELF-DIAGNOSTIC SYSTEM  . If input signal is detected, power window sub-switch is okay. If input signal is not detected, replace LCU for malfunctioning sub-switch.
