Circuit/System Description

The internal fault detection is handled inside the control module. No external circuits are involved.

Conditions for Running the DTC

The module runs the program to detect an internal fault when power up is commanded. The only requirements are voltage and ground. This

program runs even if the voltage is out of the valid operating range.

Conditions for Setting the DTC

The module has detected an internal malfunction.

Action Taken When the DTC Sets

The module refuses all additional inputs.

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.

* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 100, without a repeat of the malfunction.

Diagnostic Aids

* This DTC may be stored as a history DTC without affecting the operation of the control module.

* Do not replace a control module based only on DTC B1000 being set in history with the exception of the following control modules:

- Sensing and Diagnostic Module (SDM)

- Rollover Sensor

- Passenger Presence System Module

* If DTC B1000 is set as current, replace the appropriate control module.

Circuit/System Verification

If the DTC is set, replace the appropriate control module.
