What Does C1244 Mean?
The ABS/traction control module has detected a malfunction in the powertrain-indicated engine drag control system. Engine drag control reduces engine braking torque to prevent driven-wheel lockup during deceleration. This code indicates a communication or functional failure between the powertrain control module and the chassis stability system regarding engine torque management.
Common Causes
30%
Communication fault between the PCM and ABS/TCS module over the CAN bus network preventing engine torque data exchange
25%
PCM software calibration issue or PCM malfunction preventing proper engine drag control torque reporting
25%
ABS/TCS module internal software or hardware fault in the engine drag control processing logic
20%
Throttle body or electronic throttle control fault preventing the PCM from managing engine drag torque
Diagnostic Steps
1
Step 1: Check for additional powertrain DTCs (P-codes) in the PCM that may indicate an engine management fault preventing drag control. Also check for U-codes indicating communication faults.
2
Step 2: Verify CAN bus communication between the PCM and ABS module using live data. Both modules should show valid data exchange with matching vehicle speed values.
3
Step 3: Inspect the CAN bus wiring (typically a twisted pair) between the PCM and ABS module for damage, chafing, or corrosion at connectors.
4
Step 4: Verify the electronic throttle body operates smoothly through its full range. Check for binding, carbon buildup, or TPS signal errors.
5
Step 5: Clear all codes from both PCM and ABS modules. Test drive under deceleration conditions (engine braking downhill) and monitor for code recurrence.

The most common cause of C1244 (Powertrain Indicated Engine Drag Control Malfunction) is: Communication fault between the PCM and ABS/TCS module over the CAN bus network preventing engine torque data exchange
Typical repair costs for C1244 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Engine drag control is not functioning, which may cause driven wheels to lock during sudden deceleration on slippery surfaces. Drive cautiously, especially in wet or icy conditions, and repair soon.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1244 to identify the root cause.
