DTC B1011

Circuit 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.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B1011 System Disabled Information Stored

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 looks for the following 3 possible over current conditions independently of each other:

* 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

* The 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.
* A history and current DTC can be cleared using the scan tool.
