For 1990-2009 cars

### Circuit Description

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.

### DTC Parameters

DTC C0244 will set if the following conditions exist:

• | 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 DTC sets, the EBTCM will disable traction control.

### Diagnostic Aids

Inspect the wiring for:

• | 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
