Both C1352 and C1354 on your Lexus LS460 point to issues with the brake actuator—specifically the solenoids that control pressure to the rear wheels (left and right). These solenoids are inside the brake actuator assembly, which is part of the ABS/VSC system.
This problem is pretty common on LS460s as they age. Unfortunately, you can’t just replace the solenoids—the whole brake actuator usually has to be replaced.
Before doing that, check:
- Brake fluid level and condition (old or dirty fluid can trigger solenoid issues)
- Wiring and connectors at the actuator
- For any signs of internal brake fluid leaks
But if everything looks good and the codes keep coming back, chances are the actuator is failing internally. It’s a dealer-level part, but a good independent shop can handle the job if they have the right tools to bleed the system afterward.
