There are no DTCs output but the problem still occurs, check the circuits for each problem symptom in the order given in table below .

NOTE: When replacing the skid control ECU, sensor, etc., turn the ignition switch off.

PROBLEM SYMPTOMS TABLE - ANTI-LOCK BRAKE SYSTEM WITH EBD

Symptoms	Suspected Areas
ABS does not operate BA does not operate EBD does not operate	Check the DTC again and make sure that the normal code is output, IG power source circuit and ground circuit. Speed sensor circuit Check the brake actuator with a hand-held tester, If abnormal, check the hydraulic circuit for leakage, If the symptoms still occur even after the above circuits in suspected areas are inspected and proved to be normal, replace the skid control ECU.
ABS does not operate efficiently BA does not operate efficiently EBD does not operate efficiently	Check the DTC again and make sure that the normal code is output. Speed sensor circuit Stop lamp switch circuit Check the brake actuator with a hand-held tester. If abnormal, check the hydraulic circuit for leakage. If the symptoms still occur even after the above circuits in suspected areas are inspected and proved to be normal, replace the skid control ECU.
ABS warning light abnormal (Remain ON)	ABS warning light circuit Skid control ECU
ABS warning light abnormal (Does not light up)	ABS warning light circuit Skid control ECU
DTC of ABS check cannot be done	Check the DTC again and make sure that the normal code is output. TC terminal circuit If the symptoms still occur even after the above circuits in suspected areas are inspected and proved to be normal, replace the skid control ECU.
Sensor signal check cannot be done	TS terminal circuit Skid control ECU
VSC and/or TRAC does not operate	Check the DTC again and make sure that the normal code is output. IG power source circuit and ground circuit. Check the hydraulic circuit for leakage.
