3.CHECK CONNECTOR AND BRAKING PERFORMANCE
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Check brake effectiveness.
NOTE:
Driving the vehicle with the ABS actuator and electr ic unit (control unit) disconnected may induce DTCs in
electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to BRC-60,
"CONSULT-III Function (ABS)".
OK or NG
OK >> GO TO 4.
NG >> Perform Basic Inspection. Refer to BRC-56, "

4.CHECK WHEEL SENSORS
Check the following.
• Wheel sensor mounting for looseness
• Wheel sensors for physical damage
• Wheel sensor connectors for terminal damage or loose connections
OK or NG
OK >> Check ABS actuator and electric unit (contro l unit) pin terminals for damage and the connection of
harness connector. Reconnect ABS actuator and el ectric unit (control unit) harness connector.

1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check to see if stopping distance is still long.
NOTE:
Driving the vehicle with the ABS actuator and electr ic unit (control unit) disconnected may induce DTCs in
electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to BRC-60,
"CONSULT-III Function (ABS)".
OK or NG
OK >> Go to BRC-81, "ABS Works Frequently".
NG >> Perform Basic Inspection. Refer to BRC-56, "

ABS Does Not WorkINFOID:0000000005928501
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1.CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.
• Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-60, "CONSULT-III Function (ABS)".
