DTC Descriptors
DTC B101E 42
- ECU Software Performance Calibration Data Set Not Programmed




Circuit/System Description

When the ignition is turned ON, the radio performs a self test to verify if any critical malfunction exists within the system. Once the power-up mode is completed, the radio establishes communications with the body control module (BCM). During the power-up mode the radio checks for a valid calibration data set, if no valid calibration set is found the radio disables the system.


Conditions for Running the DTC

* The ignition must be in the RUN or ACC position.
* The system voltage is at least 9.5 volts and no more than 15.5 volts.
* All the above conditions are present for greater than 10 seconds.



Conditions for Setting the DTC

The calibration data set is not programmed in the radio.


Action Taken When the DTC Sets

The radio refuses all user inputs.


Conditions for Clearing the DTC

* A current DTC clears when the conditions for setting the DTC are no longer present.
* A history DTC clears after 50 malfunction-free ignition cycles.
* The radio receives a clear command code from the scan tool.
