PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the DTC check but the problem still o\
ccurs, check the circuits for each
problem symptom in the order given in the table below and proceed to the releva\
nt troubleshooting page.
NOTICE:
When replacing the ABS & TRACTION actuator, sensor or etc., turn the ignition switch to OFF.
SymptomSuspect AreaSee page
ABS does not operate
BA does not operate
EBD does not operate
If the symptoms still occur even after the following circuits
in suspect areas are inspected and proved to be normal,
replace the ABS & TRACTION actuator.
1. Check the DTC again and make sure that the normal code is output.
2. IG power source circuit
3. Speed sensor circuit
4. Check the brake master cylinder with a ABS actuator checker or hand±held tester.
If there is malfunction, check the hydraulic circuit for leak-
age.
