Circuit/System Verification
- Ignition ON, observe the driver door switch while commanding the Driver Door Switch Integrated Sw. Backlighting Test ON and OFF with a scan tool. The switch backlighting should turn ON and OFF between commanded states.
- If the backlighting does not turn On and OFF or remains always ON, replace the driver door lock and side window switch.
- Ignition ON, observe the driver memory/heated seat switch while commanding the Driver Door Switch Non-Integrated Sw. Backlighting Test ON and OFF with a scan tool. The switch backlighting should turn ON and OFF between commanded states.
- If the backlighting does not turn On and OFF or remains always ON, refer to Circuit/System Testing For Front Door Switch Backlighting Circuit Test.
- Ignition ON, observe the passenger door switch while commanding the Passenger Door Switch Integrated Sw. Backlighting Test ON and OFF with a scan tool. The switch backlighting should turn ON and OFF between commanded states.
- If the backlighting does not turn On and OFF or always remains ON, replace the passenger door lock and side window switch.
- Ignition ON, observe the passenger heated seat switch while commanding the Passenger Door Switch Non-Integrated Sw. Backlighting Test ON and OFF with a scan tool. The switch backlighting should turn ON and OFF between commanded states.
- If the backlighting does not turn On and OFF or remains always ON, refer to Circuit/System Testing For Front Door Switch Backlighting Circuit Test.
- Ignition ON, observe the scan tool BCM Dimming Control Signal parameter while operating the dimmer switch from high to low. The reading should change from a high percent to a low percent as the switch is rotated.
- If the scan tool dimmer control operates normal, refer to Circuit/System Testing For Interior Backlighting Circuit Test or the LED Dimming Circuit Test.
