The faults C18F9-02 and C18EA-01 are related to the electric braking system (brake booster / VDC module).
You can perform the following checks:
-Check the 12V battery (stable voltage above 12.5V)
-Check all fuses related to the ABS / braking system
-Verify power supply and ground at the brake booster
-Check the CAN network (continuity and no short circuit)
-Inspect the module connector (corrosion or poor contact)
If everything is OK, then the brake booster is most likely faulty.

I know the procedure for checking these errors. I need a diagram to check the power supply and wire continuity.
