messages displaying the same two drivers/circuits shorted to ignition/battery as-well-as shorted to ground indicates that two actuator driver circuits are
shorted together. To ensure a proper diagnosis, repair all Short Too Complex fault messages first, all common door driver circuit related fault
messages second, and all other fault messages last. In addition, always test the door driver circuits after each repair by cycling the ignition switch and
then running the Actuator Circuit Test again to ensure that no new faults exits.
