DTC Descriptors
DTC B1310
- Convertible Top Main Movement Up Sensor Circuit
Diagnostic Fault Information
Circuit/System Description
The folding top closed switch signals the folding top control (FTC) module when the folding top is closed 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. Voltage is then applied through the folding top closed switch and the hard top connected signal circuit to the FTC module. The FTC module will then continue through the operating sequences, completing the operation.
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.
Diagnostic Aids

Circuit/System Verification
1. When the folding top is in the fully closed position, the folding top closed switch is closed to voltage and the scan tool Top Closed Limit Switch parameter reading should be On.
2. When the folding top is in the open or stowed position, the folding top closed switch is open and the scan tool Top Closed Limit Switch parameter reading should be Off.
Circuit/System Testing
1. Open the hydraulic fluid bypass valve located above the folding top motor by turning it counterclockwise.
2. Manually move the folding top to access the folding top closed switch. Refer to Folding Top Manual Operation (Folding Top Manual Operation).
3. Ignition OFF, disconnect the harness connector at the folding top closed switch.
4. Ignition ON, verify the scan tool Top Closed Limit Switch parameter is Off.
• If not the specified value, test the signal circuit terminal A for a short to voltage. If the circuit tests normal, replace the FTC module.
5. Install a 3A fused jumper wire between the signal circuit terminal A and the control circuit terminal B. Verify the scan tool Top Closed Limit Switch parameter is On.
• If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the FTC module.
6. If all circuits test normal, test or replace the folding top closed switch.
