Notice:Prepare the beaker for taking the fuel.
4. Connect the shop made cable to the injector with a firing order.
5. Connect the other end of shop made cable to the positive battery cable and negative battery cable.
6. Turn the ignition switch ON.
7. Check the injector for normal spray pattern as shown in the figure. Check injector for leaks or later drop
Injector Resistance Inspection
1. Turn the ignition switch OFF.
2. Remove the fuel injector connectors.
3. Measure the fuel injector coil resistance using a multimeter.
Specified Value
14 ~ 17Ω
Notice:Replace the fuel injector if the measured value is out of the specified values. Check the connector and wire
connection between the ECM and the injector if the measured values are normal.

Circuit Description
In order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor and
carbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen sensor pro-
duces and output signal which indicates the storage capacity of the catalyst. This in turn indicates the catalyst’s ability
to convert exhaust emission effectively. If the oxygen sensor pigtail wiring, connector, or terminal is damaged. Do not
attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly, it must have a clean air
reference provided to it. This clean air reference is obtained by way of the oxygen sensor wire(s). Any attempt to repair
the wires, connector, or terminal and degrade the oxygen sensor performance.

Circuit Description
The provision for communicating with the ECM is the Data Link Connector (DLC). It is located in the instrument panel
fuse block. The DLC is used to connect the scan tool. Battery power and ground is supplied for the scan tool through
the DLC. CAN line is used to communicate with the other module such as the Transmission Control Module (TCM) and
Transfer Case Control Unit (TCCU).
Keyword 2000 Serial Data Communications
Each bit of information can have one of two lengths: long or short. This allows vehicle wiring to be reduced by transmit-
ting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streams are also priori-
tized. If two messages attempt to establish communications on the data line at the same time, only the message with
higher prioritywill must wait.

LEFT FRONT WHEEL SPEED SENSOR FAULT
KAA4F140
Circuit Description
The toothed wheel generates a voltage pulse as it
moves past the sensor. Each tooth-gap-tooth series
on the wheel generates the pulses. The electronic brake
control module (EBCM) uses the frequency of these
pulses to determine the wheel speed. The voltage gen-
erated depends on the air gap between the sensor and
the toothed wheel, and on the wheel speed.
Diagnosis
This procedure checks for a malfunctioning wheel speed
sensor, a short to ground or to voltage in the wiring, or
a contact problem in a connector.
Cause(s)
The wheel speed sensor is defective.
There is a problem in the wiring.
There is a problem with a connector.
Fail Action
ABS action is disabled, and the ABS warning lamp is
ON.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.1. This step begins an examination for a defective
wheel speed sensor.
6. This step tests the wiring for a short to voltage.
8. This step tests the wiring for a short to ground.
10. This step tests for an open or a high resistance in
the wiring.
Diagnostic Aids
Be sure that the speed sensor wiring is properly routed
and retained. This will help to prevent false signals due
to the pickup of electrical noise.
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to inspect the
wiring and the connectors carefully and completely may
result in misdiagnosis, causing part replacement with
the reappearance of the malfunction.
Use the scan tool to monitor wheel speeds during a
road test. Watch the wheel speeds being displayed on
the scan tool to see if any of the readings are unusual,
such as one sensor varying in speed from the other
three, a signal going intermittently high or low, etc. If
this does not identify the intermittent, wet the speed
sensor harness on the underside of the vehicle and
perform a road test, monitoring wheel speeds with the
scan tool.
