During top operation, the Folding Top Control (FTC) Module sends a signal to the window regulators to index the windows open on the retractable hard top request circuits. Upon completion of top operation it sends a signal to close the windows. The FTC monitors the retractable hard top request circuits for proper operation.

The Folding Top Control (FTC) module is active.

A short to ground or short to voltage is detected on one or both retractable hard top request circuits.

The top is disabled.

The fault is no longer present and the top completes one cycle.

An open on either retractable hard top request circuit will cause the windows to be inoperative during top operation.

1. Disconnect C 1 from the FTC Module.
2. Probe C 1 pin 23 with a test lamp connected to ground. The test lamp should not illuminate.

⇒	If the test lamp illuminates, repair a short to voltage.

3. Probe C 1 pin 11with a test lamp connected to ground. The test lamp should not illuminate.

⇒	If the test lamp illuminates, repair a short to voltage.

4. If circuits test OK, replace FTC Module.
