Gen3 - Fault Code - N09

Notes
This fault code can appear when the stow switch has an internal contact fault
The stow switch is never in a disconnected state. Depending on whether the switch is activated or not, it's always either connected to 12 Volts or Ground. The N09 fault is displayed when the switch is electrically in a disconnected state from either the 12 Volt line or the Ground.

Furthermore, it is possible for the stow switch to develop a fault where it makes electrical contact for part of it's travel but not the rest (in either/both up-stroke/down-stroke).

The easiest method of testing the switch is to look at the 'Stow Switch' field on the Gen 3 display.  To achieve this task, the operator needs to navigate to the 'Diagnostics Menu' screen.

The navigation path from the Gen 3 main screen is: 
1. Press the center 'Enter' button on the 5 button user control.
2. Navigate to the 'System Menu'.
3. Navigate to the 'Diagnostics Menu'.
4. Observe the 'Stow Switch' field on the display unit whilst exercising the CALM stow switch.

Info
Exercising the Stow Switch through full movement
1. Observe the Stow switch field.
2. Press the Stow switch up-ward until an engage click is heard. 
3. The state on the display should change from - Inactive to Active.
4. Continue pressing slowly through the rest of the up-ward cycle and keep observing the Stow Switch state - it should remain in the Active state.
5. Release the stow switch and the state on the display should revert back to the - Inactive state.
6. Press the Stow switch down-ward until an engage click is heard. 
7. The state on the display should change from - Inactive to Active.
8. Continue pressing slowly through the rest of the down-ward cycle and keep observing the Stow Switch state - it should remain in the Active state.
9. Release the stow switch and the state on the display should revert back to the - Inactive state.

If your observations are not the same as described above then it's possible that your stow switch is internally faulty and you need to open an EQSS support request. Upon opening a support request, you can then send the Gen 3 cable reeler back to EQSS for diagnosis/repair.
