PROBLEM SYMPTOMS TABLE
If there are no DTCs output and the problem still occurs, check the circuits for each problem symptom in the order given in the following table and proceed to the relevant troubleshooting page.
NOTICE:
When replacing the brake actuator assembly, sensors, etc., turn the ignition switch off.
HINT:
Symptom |
Suspected Area |
See page |
---|---|---|
ABS, BA and/or EBD does not operate. |
Check for DTCs again and make sure that the normal system code is output. |
|
