Circuit/System Description
Battery positive voltage is supplied to the folding top control (FTC) module from the BAT MAIN 2 fuse. When commanded, this voltage is used by the FTC module to power the folding top pump motor through the motor control circuits. When an over current 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
| • | High over current--The FTC module will set DTC B1011 when the measured current exceeds 90 amps for 30 milliseconds. This tests runs every 3 milliseconds. |
| • | Medium over current--The FTC module will set DTC B1011 when the measured current exceeds 60 amps for 1 seconds. This tests runs every 3 seconds. |
| • | Low over current--The FTC module will set DTC B1011 when the measured current exceeds 40 amps for 30 seconds. This tests runs every 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. |

Circuit/System Testing
- Ignition OFF, disconnect the X431 inline harness connector.
- Connect a test lamp between the control circuit terminal A4 and the control circuit terminal B4.
- 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 all circuits test normal, replace the folding top pump motor assembly.
| ⇒ | 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. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
