Problem Symptoms Table

If a normal code is displayed during the DTC check 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 page.

PROBLEM SYMPTOMS TABLE - ABS AND TRACTION CONTROL SYSTEM

Symptom	Suspect Area
ABS does not operate	Only when 1 to 4 are all normal but the problem still occurs, replace the ABS & TRAC ECU. Check the DTC reconfirming that the normal code is output IG power source circuit Speed sensor circuit Check the ABS & TRAC actuator with a checker. If abnormal, check the hydraulic circuit for leakage
ABS does not operate efficiently	Only when 1 to 4 are all normal but the problem still occurs, replace the ABS & TRAC ECU. Check the DTC reconfirming that the normal code is output Speed sensor circuit Stop light switch circuit Check the ABS & TRAC actuator with a checker. If abnormal, check the hydraulic circuit for leakage
ABS warning light abnormal	ABS warning light circuit ABS & TRAC ECU
DTC check impossible	Only when 1 and 2 are all normal but the problem still occurs, replace the ABS & TRAC ECU. ABS warning light circuit TRAC OFF indicator light circuit Tc terminal circuit
Speed sensor signal check impossible	Ts terminal circuit ABS & TRAC ECU
TRAC does not operate	Only when inspection circuits for each problem symptom are all normal but the problem still occurs, replace the ABS & TRAC ECU. Check the DTC, reconfirming that the normal code is output IG power source circuit Check the hydraulic circuit for leakage Speed sensor circuit
SLIP indicator light abnormal	SLIP indicator light circuit
TRAC OFF indicator light abnormal	Only when inspection circuits for each problem symptom are all normal but the problem still occurs, replace the ABS & TRAC ECU. TRAC OFF indicator light circuit TRAC cut switch circuit
