C0076PWM for Traction Control
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- Covers the pulse-width-modulated signal used within the traction control interface, for example a PWM torque-request or status line exchanged between the stability and powertrain controllers or driving a traction-related actuator. The module monitors the PWM signal's duty cycle, frequency and presence and sets this code when it is missing, out of range or implausible. Traction-control patents describe the controller commanding torque reduction and actuators through defined signal interfaces; a corrupted PWM link breaks that chain. A fault limits traction control and sets the ABS/ESC warning lamp while base braking remains, usually alongside the torque request/deliver codes. No code-specific public bulletin was confirmed; the entry follows the SAE J2012 generic definition and traction-control signalling design.
