HINT:

This code is detected when a problem is determined in the ABS and TRACTION actuator assembly.

The ABS motor relay is in the ABS and TRACTION actuator assembly.

Therefore, motor relay circuit inspection and relay unit inspection cannot be performed. Be sure to check if the DTC code is output before replacing the ABS and TRACTION actuator assembly.

1. Clear the DTCs (See DTC CHECK/CLEAR  ).
2. Turn the ignition switch to the ON position.
3. Are the same DTCs recorded?

NO : END 

YES : REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
