TROUBLE DIAGNOSIS
Revision: 2006 July 2007 FX35/FX45
Note 1: After completing repairs of shorted sensor circuit, when turning ignition switch ON, ABS warning lamp turned on. Make t hat ABS
warning lamp turned off while driving vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute according to self-
diagnosis procedure. In addition, if wheel sensor 2 is displayed for wheels, check wheel sensor circuit and also check ABS actu ator and
electric unit (control unit) power voltage.
Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line
first.
Note 3: “ACTUATOR RLY” on the CONSULT-II self-diagnostic results indicates the malfunction of actuator relay or circuit. Actuat or relay
is imbedded in ABS actuator and electric unit (control unit).
Note 4:Only AWD models. DECEL G SEN SET

TEST ITEM
Solenoid Valve
NOTE:
The example shown is for the front right wheel. The procedure for the other wheels is the same as given
below.

When performing an active test of the ABS function, select the
main item for each test item. In addition, when performing an
active test of the VDC/TCS function, select the item menu for
each test item.

For the ABS solenoid valve, touch “UP” “KEEP” “DOWN”, and
for the ABS solenoid valve (ACT), touch “UP” “ACTUATOR UP”
“ACTUATOR KEEP”, and check to make sure that all solenoid
valve (in, out) are operating as given in the table below.
*: ON for 1 to 2 seconds after the touch, and then OFF
NOTE:

If active test is performed with brake pedal depressed, pedal stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds after operation starts.

After “TEST IS STOPPED” is displayed, touch “BACK” and perform the test from the Step 8.
ABS Motor
Touch “ON” and “OFF” on the screen. Make sure ABS motor relay
operates as shown in table below.
NOTE:

If active test is performed with brake pedal depressed, pedal
stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds
after operation starts.

TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Wheel Sensor CircuitNFS000NJ
DTC C1101-C1108, C1115
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 sensor terminal with tester etc.,
because sensor is an active sensor.

Do not expand terminal of connector with a tester terminal stick, when it does the inspection with
tester.
INSPECTION PROCEDURE
1. CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear, and size within the standard values?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2. CHECK SENSOR AND SENSOR ROTOR

Check condition of the sensor mount (for looseness, etc.).

Check surface of front sensor rotor rubber for damage.

Check rear sensor rotor for damage.
OK or NG
OK >> GO TO 3.
NG >> Repair sensor mount or replace sensor rotor.
3. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 4.
NO >> INSPECTION END
4. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector and malfunctioning wheel sensor con- nector E46 (FR-LH), E33 (FR-RH) or B69 (RR). Check terminal for deformation, open circuit, poor con-
tact, etc., and repair or replace if any malfunctioning condition is found.
2. Reconnect connectors, drive at a speed of approximately 30 km/h (19 MPH) or more for approximately 1 minute, and perform self-diagnosis.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.
