TROUBLE DIAGNOSIS
Inspection 1 Wheel Sensor System
AFS0011D
INSPECTION PROCEDURE
After using the CONSULT-II SELF-DIAG RESULTS to determine the location of the malfunctioning wheel sen-
sor, check all areas to determine the component to be replaced.
CAUTION:
? Do not measure the resistance value and also voltage between the sensor terminal with tester etc.,
because the sensor is an active sensor.
? Do not expand the terminal of the connector with a/the tester terminal stick, when it does the
inspection with the tester.
1. TIRE INSPECTION
Check air pressure, wear, and size.
Are the air pressure, wear, and size within the standard values?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2. SENSOR AND SENSOR ROTOR INSPECTION
? Check the condition of the sensor mount (for looseness, etc.).
? Check the surface of the front sensor rotor rubber for damage.
? Check the rear sensor rotor for damage.
OK or NG
OK >> GO TO 3.
NG >> Repair the sensor mount or replace the sensor rotor.
3. SELF-DIAGNOSIS RESULT CHECK
Check self-diagnosis results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 4.
NO >> Inspection End
4. CONNECTOR INSPECTION
1. Disconnect ABS control unit connector E51 and the malfunctioning wheel sensor connector E42 (FR - LH)
or E27 (FR - RH) or T5 (RR - RH, LH). Check the terminal to see if it is deformed, disconnected, loose,
etc., and replace it if any non-standard condition is found.
2. Reconnect the connector, drive at a speed of approximately 30 km/h (19 MPH) for approximately 1
minute, and conduct self-diagnosis.
OK or NG
OK >> The connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.
Self-diagnosis results

FR LH SENSOR-1, - 2
RR RH SENSOR-1, -2
