Traction Control Desired Torque

Scan Tool Range 0 percent to 100 percent. This represents the PWM signal from the Electronic Brake and Traction Control Module (EBTCM). The EBTCM reduces the Traction Control Desired Torque signal pulse width when a drive wheel slippage situation is detected. The PCM monitors the Traction Control Desired Torque signal and reduces drive wheel slippage as necessary by retarding the spark timing or increasing the air-to-fuel ratio. The PCM can also turn OFF up to three fuel injectors if the Traction Control Desired Torque signal indicates enough drive wheel slippage. A problem with the Traction Control Desired Torque signal should cause DTC P1571 to set.
