Motor Timeout

To protect the tail door window motor from damage, the motor outputs have a fail-safe inhibit relative to the window height. This prevents the motor from being overdriven. If the fail-safe limit is reached, the CCU will energise the tail window down relay, to fully lower the window, and change the window position setting to uncalibrated. The calibration procedure will need to be performed to restore normal tail door window operation.
