B1058 - Recirculation Door Control Circuit/Performance: Notes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Volkswagen Routan, 2013 Volkswagen Routan, 2012 Volkswagen Routan, 2011 Volkswagen Routan, and 2010 Volkswagen Routan. However, it is still accessible from the selected car via links, so may be relevant.

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS information.

Theory of Operation

The A/C heater control drives the recirculation door actuator via the recirculation door driver and the common door driver 2.

>>When Monitored:<< With the ignition on.
>>Set Condition:<< If the A/C heater control detects a short to ground or to voltage on the recirculation door driver, the passenger blend door driver, the driver blend door driver, the mode door driver, or the common door driver 2 circuits while attempting to drive the recirculation door driver.
