For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

When the front door is opened, the puddle lamp operates at the same time and conditions as the overhead courtesy lamps. The Body Control Module sends the command to the Door Module to turn it on or off.

- When Monitored:
Whenever the Puddle (courtesy) lamp is on.

- Set Condition:
When the Driver Door Courtesy Lamp Driver circuit falls below 3.0 volts for over 2000 ms. and the above conditions are met, this code will set.
