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.
DTC C0141, C0146, C0151 & C0156: TCS Solenoid Circuit Malfunction
C0141 - Left Side TCS Solenoid No. 1 Circuit
C0146 - Left Side TCS Solenoid No. 2 Circuit
C0151 - Right Side TCS Solenoid No. 1 Circuit
C0156 - Right Side TCS Solenoid No. 2 Circuit
The ABS control module controls valve function by grounding the solenoid circuit when necessary. Solenoids No. 1 are prime valves and solenoids No. 2 are isolation valves. DTC will set if ABS control module detects an open, short to ground or short to voltage on solenoid circuit(s) inside control module. If this condition is present, ABS indicator light will illuminate, ABS will be disabled and Dynamic Rear Proportioning (DRP) will be limited to hold function only. Replace ABS control module as necessary.
