Traction Control Desired Torque
Scan tool range
0-100 percent. Represents the pulse width modulation (PWM) signal from the electronic brake and traction control module. 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 the drive wheel slippage as necessary by retarding the spark timing, or by 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 a DTC to set.
