C1345 Lexus Code - Linear Solenoid Valve Offset Learning Undone
Quick Answer
The skid control ECU stores and corrects the difference in each individual part such as the stroke sensor, actuator soelnoid, and stroke simulator solenoid. Common causes include Initialization of linear solenoid and calibration undone, Faulty Skid Control ECU, Skid Control ECU harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

The C1345 - Linear Solenoid Valve Offset Learning Undone code appears after brake service because the ABS system needs to be recalibrated to account for the new brake components. Since your ABS lights stayed on after replacing the brakes, the system has detected that the solenoid valve offset has not been relearned.
What Causes C1345?
- The ABS system requires a solenoid valve learning procedure after brake system components are changed (such as brake pads, rotors, or calipers).
- The ABS actuator and pump assembly need to relearn their proper settings for brake pressure control.
How to Fix It:
1. Perform ABS Solenoid Valve Offset Learning (Calibration)
To clear the C1345 code, you must perform the linear solenoid valve learning process using a scan tool that supports ABS functions, such as:
- Toyota Techstream (Recommended)
- An advanced OBDII scanner that supports Toyota/Lexus ABS systems
Steps Using Toyota Techstream:
- Connect the scan tool and navigate to the ABS system.
- Select "Solenoid Valve Offset Learning" or "ABS Linear Valve Calibration."
- Follow the on-screen prompts and let the system complete the relearning process.
- Clear the code and restart the vehicle.
2. Manual Calibration (If No Scanner)
If you don’t have a scanner, you can try this manual method:
- Turn the ignition ON (do not start the engine).
- Press the brake pedal firmly multiple times (around 20-30 presses).
- Drive the vehicle at low speed (under 10 mph) for a short distance to allow the ABS system to adjust.
- If the ABS light remains, a scanner may be required.
3. Check for Additional Issues
- If the calibration doesn’t work, inspect the ABS actuator wiring and connectors to ensure they were not disturbed during brake replacement.
- Check for other stored ABS-related codes that might indicate additional issues.
Final Steps
- If you successfully perform the calibration, the ABS light should turn off.
- If the light remains on and the code persists, a professional scan tool is needed to reset the system properly.
