Diagnostic Fault Information









Circuit/System Description

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.

Conditions for Running the DTC

The FTC module monitors for over current only when the power folding top pump motor is active.

Conditions for Setting the DTC

The FTC module will set DTC B1011 when the measured current exceeds 81 amps for 100 milliseconds.

Action Taken When the DTC Sets

* 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.

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 Testing

1. If needed, manually open the deck lid to access the hydraulic fluid bypass valve.
2. Turn the hydraulic fluid bypass valve counterclockwise to inhibit folding top movement. Refer to Folding Top Manual Operation (Folding Top Manual Operation).
3. Ignition OFF, disconnect the harness connector at the folding top pump motor.
4. Connect a test lamp between control circuit terminal A and control circuit terminal B.
5. Ignition ON, command the Pump Motor A Direction and Pump Motor B Direction On and Off with a scan tool. The test lamp should turn ON when commanding the Pump Motor A Direction and Pump Motor B Direction states.

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.

6. If all circuits test normal, replace the folding top pump motor assembly.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
