Engine Torque Control Cut Signal Low

What this code means

The PCM has detected a low signal on the engine torque control cut circuit from the traction control or stability control module. This signal requests the PCM to reduce engine torque when wheel slip is detected.

Symptoms

• Check Engine Light
• Traction control may not reduce engine power when needed
• Traction control warning light
• Stability control malfunction

Common causes

• Wiring issue in torque control signal circuit
• Faulty traction control module
• PCM input circuit fault
• Corroded connector in torque control circuit
• ABS/stability control module failure

Diagnostic steps

1. Check torque control signal at PCM on scan tool
2. Inspect wiring between stability control module and PCM
3. Test circuit for shorts to ground
4. Check stability control module for DTCs
5. Verify connector condition

Repair notes

Repair wiring in the torque control cut circuit or replace the stability control module if at fault.
