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 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

* Ignition is in ON or ACCY
* 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

Radio functions are disabled

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.
