B16A3-15-PASSENGER WINDOW SWITCH BACKLIGHTING - CIRCUIT SHORT TO BATTERY OR OPEN







- When Monitored:
Whenever the module is awake.

- Set Condition:
When the Passenger Window Switch Illumination Driver circuit current draw is greater than 120mA for over 2000 ms. and the switch illumination output is turned off or there is no current draw when the switch illumination is turn on.





1. CHECK FOR OPEN CIRCUIT
1. With the scan tool, record and erase DTCs.
2. Make sure the passenger window lock out switch is on.
