DTC DESCRIPTORS

DTC 1307 58
Movable Roof Latch Signal Circuit incorrect reaction after event

DTC 1307 59
Movable Roof Latch Signal Circuit circuit/component protection time out

CIRCUIT/SYSTEM DESCRIPTION
S14 is the Folding Top Front Latch Actuator Position switch. The folding top control (FTC) module uses S14 to determine when the top is latched in both the open and closed positions. S14 closes and pulls the signal circuit low when the top is latched.

CONDITIONS FOR RUNNING THE DTC
The Folding Top is being commanded.

CONDITIONS FOR SETTING THE DTC
- An open or short to ground on the signal circuit of S14.
- An open on the low reference circuit of S14.

ACTION TAKEN WHEN THE DTC SETS
The top may be disabled and will not operate properly.

CONDITIONS FOR CLEARING THE DTC
The fault is no longer present and the top completes one cycle.

DIAGNOSTIC AIDS
- A short to B+ may damage S14 and cause a B1307 58 to set.
- A weak battery could cause the top to operate slowly and set B1307 59.

CIRCUIT/SYSTEM VERIFICATION

CIRCUIT/SYSTEM TESTING
1. Disconnect S14.
2. Ignition ON, probe the signal circuit of S14 with a test lamp connected to ground. The test lamp should illuminate.
- It the test lamp does not illuminate, test for an open or short to ground on the signal circuit.
- If circuit tests OK, replace FTC Module.
3. Use a scan tool to monitor the Folding Top Bell Crank Sw. parameter.
4. Connect a fused jumper wire between the signal circuit and the low reference circuit of S14. The scan tool should indicate Over Center.
- If the scan tool does not indicate Over Center, test the low reference circuit for an open or high resistance.
- If circuit tests OK, replace FTC Module.
5. If circuits test OK, replace S14.
