Circuit Description

Traction control is simultaneously controlled by EBCM and PCM. PCM sends a delivered torque message via a Pulse Width Modulated (PWM) signal to EBCM confirming delivered torque level for proper traction control system operation. EBCM supplies pull up voltage.

DTC sets when ignition voltage is present and PWM signal is out of range or no signal is received for a period of 2 seconds.
