3.CHECK SENSOR AND SENSOR ROTOR
lCheck sensor rotor for damage.
lCheck wheel sensor for damage, disconnection or looseness.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace the malfunctioning component.
4.CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E63 and
malfunctioning wheel sensor connector E66 (FR - LH), E77 (FR - RH), C10 (RR - LH) or C11 (RR - RH).
Check terminal to see if it is deformed, disconnected, loose, etc., and repair or replace it if any malfunction
condition is found.
2. Reconnect connectors and check that interference with other parts has not cut wheel sensor cables, drive
vehicle at 30 km/h (19 MPH) or more for approximately 1minute, and perform self-diagnosis.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.
5.CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF and disconnect wheel sensor connec-
tor E66 (FR - LH), E77 (FR - RH), C10 (RR - LH) or C11 (RR -
RH) and ABS actuator and electric unit (control unit) connector
E63.
2. Check continuity between terminals. (Also check continuity
when steering wheel is turned right and left and when sensor
harness inside wheel well is moved.)
OK or NG
OK >> GO TO 6.
NG >> Repair or replace harness and connector that have malfunction.

*1: The input signal is sent to the ECM through CAN communication line.
*2: The output signal is sent from the ECM through CAN communication line.
Fuel Injection Control SystemEBS01KCE
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.

TROUBLE DIAGNOSIS
Basic Inspection
EBS01KCV
Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;
lHeadlamp switch is OFF.
lOn vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.
lAir conditioner switch is OFF.
lHeater fan switch is OFF.
lRear defogger switch is OFF.
lHeat up switch is OFF.
lSteering wheel is in the straight-ahead position, etc.
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related incident.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-8, "
PERIODIC MAINTENANCE".
3. Open engine hood and check the following:
–Harness connectors for improper connections
–Vacuum hoses for splits, kinks, or improper connections
–Wiring for improper connections, pinches, or cuts
4. Start engine and warm it up to the normal operating tempera-
ture.
>> GO TO 2.
2.PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
Connect CONSULT-II to the data link connector.
Without CONSULT-II
Install diesel tacho tester to the vehicle.
>> GO TO 3.

Component DescriptionEBS01KI4
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
Refer toEC-355, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)"for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeEBS01KI5
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KI6
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
