Circuit Description
The RDM2 Fuse supplies battery positive voltage to the roof door module (RDM) at all times. The RDM uses this supply for the control of the header latch motor.
Conditions for Running the DTC
| • | Battery voltage between 9-16 volts |
| • | The roof may be active or inactive |
Conditions for Setting the DTC
The DTC will set when the RDM senses no voltage input from the RDM2 fuse.
Action Taken When the DTC Sets
The RDM cannot control the header latch motor.
Conditions for Clearing the DTC
| • | When the fault is no longer present, the RDM will change the current DTC to a history DTC. |
| • | The RDM will clear the history DTC after 50 fault free ignition cycles. |
| • | A current or history DTC can also be cleared using a scan tool. |
