Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code P1571, Traction Control Desired Torque Out Of Range: Notes
Traction control system uses ABS system in conjunction with control module fuel and ignition controls to limit drive wheel slippage during acceleration. Control module portion of traction control system uses spark timing retardation, air/fuel mixture alteration or turning off up to 3 injectors to reduce engine torque. Control module determines amount of torque reduction by monitoring PWM signal from EBTCM. Control module also provides a delivered torque PWM signal to EBTCM to inform of engine torque.
When Code 1571 is set, control module will command EBTCM to set ABS/TCS Code 124, turn off traction control system and light TCS indicator or "SERVICE TRAC CTL" indicator. Code 1571 does not light "SERVICE ENGINE SOON" indicator.
- Checks circuit for an open or short to ground.
- Ensures EBTCM is proving a proper PWM signal to control module.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
