What it means
C0141 is reserved in the generic SAE/ISO code list, so it has no standard generic fault meaning. A vehicle may use it for a manufacturer-specific fault, which requires the vehicle's service information to interpret.
How it works
C0141 is reserved in the generic SAE/ISO code list, so its title alone does not confirm a fault in the left TCS solenoid #1. A vehicle maker may assign the code a different meaning; the vehicle-specific code definition is needed before identifying the monitored circuit or setting condition.
Common causes
Most likely first.
- Manufacturer-specific code assignment
- Incorrect scan tool code lookup
Symptoms
- ABS or traction control warning may appear
- Symptoms depend on the vehicle-specific fault
How to diagnose it
- Check the scan tool’s code description and vehicle identification to confirm that C0141 is being decoded for this exact vehicle.
- Record freeze-frame data and any related ABS or traction-control codes, which may point to the system or condition that triggered the manufacturer-specific code.
- Look up C0141 in the vehicle’s service information and confirm whether it refers to the left TCS solenoid #1 or another fault.
- If the service information confirms the solenoid assignment, inspect its wiring and connector for disconnection, corrosion, chafing, or damage.
- Test the identified circuit and solenoid using the vehicle-specific procedure and compare results with the manufacturer’s specification before suspecting the control module.
Common fixes
- Use a scan tool with the correct vehicle-specific code definition to verify the fault.
- Repair damaged or poorly connected wiring or connectors identified by the applicable diagnostic procedure.
- Repair or replace the component identified by the vehicle-specific test results.
- Repair the brake or stability control module only if its circuit fault is confirmed.
Can I keep driving?
If an ABS or traction-control warning is on, assume that assistance may be limited and drive cautiously, especially on slippery roads. The code’s title may not match its meaning on your vehicle, so confirm the vehicle-specific definition before deciding what system is affected.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
