VDC/TCS/ABS SYMPTOMS


Symptom Table


PROBLEM SYMPTOMS TABLE
If there are no DTCs output but the problem still occurs, check the circuits for each problem symptom in the order given in the table below and proceed to the relevant troubleshooting.

CAUTION:
When replacing the brake ECU, sensor, etc., make sure that the ignition switch is turned OFF, the stop lamp switch is off, and 2 minutes have elapsed since the driver's door was closed.

NOTE:
- Inspect the fuse and relay before investigating the suspected areas shown in the table below.
- Inspect each malfunctioning circuit in numerical order for the corresponding symptom.
- Since the oil passage is blocked off by the master cut solenoid during Electronically Controlled Brake control, there is no kickback (vibration) to the brake pedal, creating a quiet operating sound even while the ABS is operating.
