C0244

PWM DELIVERED TORQUE MALFUNCTION
Traction control is simultaneously controlled by the electronic brake and traction control module (EBTCM) and the powertrain control module (PCM) engine control module (ECM). The PCM/ECM sends a delivered torque message via a pulse width modulated (PWM) signal to the EBTCM confirming the delivered engine torque level for proper traction control system operation. The EBTCM supplies the pull up voltage.

CODE PARAMETERS
DTC C0244 will set if:
^ There is an interruption in the delivered torque circuit between the EBTCM and PCM/ECM.
^ The EBTCM receives an out of range or no signal for 2 seconds continuously.
^ Ignition voltage is present and the EBTCM detects engine RPM greater than 480.
^ When this trouble code set the EBTCM will disable traction control.

DIAGNOSTIC AIDS
^ It is very important to thoroughly inspect wiring components and connectors, Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
^ Inspect any circuitry that may be causing the complaint for the following conditions:
- Backed out terminals
- Improper mating
- Broken connector locks
- Improperly formed or damaged terminals
- Poor terminal-to-wiring connections.
- Physical damage to the wiring harness.
^ Possible causes for DTC C0244 to set:
- Open in the delivered torque circuit
- The delivered torque circuit shorted to ground or voltage
- Communication frequency problem
- Communication duty cycle problem
- The delivered torque circuit has a wiring problem, terminal corrosion, or poor connections
- EBTCM not receiving information from PCM/ECM
