Circuit Description
The folding top closed switch signals the folding top control (FTC) module when the folding top closes against the windshield header. The FTC module checks the signal circuit at least once every 300 milliseconds. The folding top closed switch will close as the RH receiver detects the RH pin from the folding top. The accessory voltage supplied to the folding top closed switch will be applied through the limit switch through the hard top connected signal circuit, to the FTC module. The FTC module will then continue through the operating sequences, completing the operation.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B1310 Convertible Top/Moveable Roof Main Movement Up Sensor Circuit
Conditions for Running the DTC
The battery voltage is between 9-16 volts
Conditions for Setting the DTC
The FTC module detects the folding top closed switch is active, closed, when the folding top position sensor indicates the top is open, past the folding top open reference position.
Action Taken When the DTC Sets
| • | Stores a current and history DTC B1310 in the FTC module. |
| • | The folding top operation is suspended. |
| • | The FTC module sends a class 2 message to the driver information center (DIC), displaying TOP NOT SECURE. |
Conditions for Clearing the DTC
| • | This DTC will clear on the current status after the condition for setting the fault is corrected. |
| • | A history DTC will clear after 50 consecutive ignition cycles without a fault present. |
| • | History and current DTC can be cleared using the scan tool. |
Diagnostic Aids
If the DTC does not reset after the code is cleared, then the switch may be the intermittent fault. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
