Battery positive voltage is supplied to the folding top control (FTC) module from the BATT 2 fuse located in the underhood fuse block. When commanded, this voltage is used by the FTC module to power the folding top pump motor through the motor control circuits. When an overcurrent condition is detected, the FTC module disables the folding top pump motor in order to protect the internal FTC module circuitry.
The FTC module monitors for over current only when the power folding top pump motor is active.
The FTC module will set DTC B1011 when the measured current exceeds 81 amps for 100 milliseconds.
• | All folding top functions in progress are aborted, including calibrations of the folding top. |
• | The FTC module will suspend operation of the folding top pump motor. |
• | 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. |
The Rear Compartment Lid is also referenced as the Deck Lid for this vehicle.

⇒ | If the test lamp remains OFF during either of the commands, test for a short to ground on either control circuit. If the circuits test normal, replace the FTC module. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
