What Does P1571 Mean?
The powertrain control module has detected a malfunction in the traction control system communication or operation. The PCM cannot properly coordinate engine torque reduction for traction control intervention.
Common Causes
30%
Failed wheel speed sensor providing incorrect data
25%
Communication fault between ABS module and PCM
25%
Faulty ABS/traction control module
20%
Low system voltage or battery issues affecting module communication
Diagnostic Steps
1
Step 1: Check for additional ABS or traction control codes in all modules
2
Step 2: Verify all wheel speed sensors are reading properly and consistently
3
Step 3: Test communication between ABS module and PCM using bidirectional controls
4
Step 4: Inspect CAN bus wiring and connections for damage or corrosion
5
Step 5: Verify battery voltage and charging system operation under load
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
The powertrain control module has detected a malfunction in the traction control system communication or operation. The PCM cannot properly coordinate engine torque reduction for traction control intervention.
The most common cause of P1571 (Powertrain Indicated Traction Control Malfunction) is: Failed wheel speed sensor providing incorrect data
Typical repair costs for P1571 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Moderate safety concern. Traction control may be disabled reducing vehicle stability on slippery surfaces. Drive cautiously.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1571 to identify the root cause.
