Details of the c0271 OBD Code
C0271 pertains to a fault in the ABS/TCS system related to the motor circuit.
OBD code C0271 means a fault has been detected in the ABS/TCS Motor Circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects an issue with the motor circuit of the Antilock Brake System (ABS) or Traction Control System (TCS).
The EBCM monitors the motor circuit for proper voltage levels and operation to ensure the ABS and TCS functions work correctly.
If there is a fault in the motor circuit, the EBCM will set code C0271 to indicate the issue.
Mechanic’s Tech Notes
Code C0271 indicates a fault in the ABS/TCS system related to the motor circuit.
OBDII code C0271 indicates a fault with the TCM (Transmission Control Module) power and ground circuit.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage and continuity.
Utilize a scan tool to confirm TCM communication over the CAN network.
Visually inspect wiring harnesses and connectors for any damage, corrosion, or loose connections.
Ensure connector pins are intact.
If no visible issues are found, consider reprogramming or reflashing the TCM.
