DTC C1244 (cont'd):

DTC C1244

Circuit Description
Engine drag control (EDC) The EBCM sends a engine drag control (EDC) request via a dedicated data line. The PCM supplies a pull up voltage of 5 volts that the EBCM switches to ground to create the signal

Conditions for Running the DTC
The engine is running.

Conditions for Setting the DTC
The EBCM receives a serial data message from the PCM indicating that the EDC circuit has failed.

Action Taken When the DTC Sets
^ The EBCM disables the EDC for the duration of the ignition cycle.
^ The DIC displays the Service Stability System message.
^ The ABS/TCS remains functional.

Conditions for Clearing the DTC
^ The condition for the DTC is no longer present and the DTC is cleared with a scan tool.
^ The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids
The following conditions can cause this concern:
^ An open in the EDC control circuit.
^ An short to ground or voltage in the EDC control circuit.
^ A wiring problem, terminal corrosion, or poor connection in the EDC control circuit.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
9. This vehicle is equipped with a PCM which uses an Electrically Erasable Programmable Read Only Memory (EEPROM). When replacing the PCM, the replacement PCM must be programmed.
