Problem Symptoms Table

WARNING: This page is about a different car, the 2006 Toyota Tundra and 2005 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

If a normal system 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. Then, proceed to the relevant troubleshooting step.

NOTE: When replacing the master cylinder solenoid, sensor, etc., turn the ignition switch OFF.

PROBLEM SYMPTOMS TABLE - ANTI-LOCK BRAKE SYSTEM WITH EBD

Symptom	Suspected Area
ABS does not operate BA does not operate EBD does not operate	Check the DTC again and make sure that the normal system code is output IG power source circuit and ground circuit Speed sensor circuit Check the hydraulic brake booster with the hand-held tester. (Check hydraulic brake booster operation using the active test function.) If abnormal, check the hydraulic circuit for leakage If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
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 system code is output Speed sensor circuit Stop light switch circuit Check the hydraulic brake booster with the hand-held tester If abnormal, check the hydraulic circuit for leakage If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
ABS warning light abnormal	ABS warning light circuit Master cylinder solenoid (skid control ECU)
ABS DTC check cannot be done	Check the DTC again and make sure that the normal system code is output TC terminal circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
Sensor signal check cannot be done	TS terminal circuit Master cylinder solenoid (skid control ECU)
VSC and/or TRAC does not operate	Check the DTC again and make sure that the normal system code is output IG power source circuit and ground circuit Check the hydraulic circuit for leakage Speed sensor circuit Yaw rate/Deceleration sensor circuit Steering sensor circuit 4WD switch circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
SLIP indicator light abnormal	SLIP indicator light circuit Master cylinder solenoid (skid control ECU)
VSC OFF indicator abnormal	Check the DTC again and make sure that the normal system code is output TRAC control switch circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
VSC DTC check cannot be done	Check the DTC again and make sure that the normal system system code is output TC terminal circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
VSC TRAC warning light abnormal	Check the DTC again and make sure that the normal code is output VSC TRAC warning circuit If the symptoms still occur even after the above circuits in suspect areas are inspected and proved to be normal. replace the master cylinder solenoid
AUTO LSD does not operate	Check the DTC again and make sure that the normal system code is output AUTO LSD switch circuit 4WD switch circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
AUTO LSD indicator abnormal	Check the DTC again and make sure that the normal system code is output AUTO LSD indicator circuit If the symptoms still occur even after the above circuits are inspected and proved to be normal, replace the master cylinder solenoid
VSC warning buzzer abnormal	VSC warning buzzer circuit
BRAKE warning light abnormal	BRAKE warning light circuit Master cylinder solenoid (skid control ECU)
