Circuit Description

The Electronic Brake and Traction Control Module (EBTCM) controls the Pulse Width Modulation (PWM) on the desired torque circuit while monitoring the wheel speed sensors to detect slippage. PCM monitors the PWM signal and reduces engine torque as needed by retarding ignition timing, decreasing boost duty cycle, increasing air/fuel ratio, or in severe cases shuts off up to 3 fuel injectors.

PCM sends a PWM signal to the EBTCM on the delivered torque circuit informing EBTCM of response made to the desired torque signal. DTC will set and traction control disabled when there is a problem with the delivered torque signal circuit. And ABS/TCS DTC may also be set.

Conditions for setting this DTC:

• Ignition on.
• Improper voltage level detected on output circuit for traction control delivered torque output circuit.
• Conditions present for at least 30 seconds.
