DIAGNOSTIC TROUBLE CODE (DTC) 04
RIGHT FRONT WHEEL SPEED SENSOR FAULT
KAA4F150
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 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.

WHEEL SPEED SENSOR FREQUENCY ERROR
KAA4F180
Circuit Description
The toothed wheel generates a voltage pulse as it
moves past the wheel speed sensor. Each tooth-gap-
tooth series on the wheel generates the pulses. The
electronic brake control module (EBCM) uses the fre-
quency of these pulses to determine wheel speed. The
voltage generated depends on the air gap between the
wheel speed sensor and the toothed wheel, and on the
wheel speed.
Diagnosis
This DTC will set when the EBCM cannot identify which
wheel speed sensor is causing the malfunction. It is
nec-essary to check all wheel speed sensors and
associated wiring to determine the cause of the DTC.
Cause(s)
Incorrect number of teeth on the toothed wheel.
Damaged or broken teeth on the toothed wheel.
Discontinuity or short in speed wheel speed sensor
wiring.

STOPLAMP SWITCH FAULT
KAA4F230
Circuit Description
When the brake pedal is pressed, the contacts on the
brake light switch close to illuminate the brake lights.
Battery voltage is also applied to terminal 48 of the
elec-tronic brake control module (EBCM), which signals
the ABS controller that the brakes are applied and ABS
may be needed. Without this, signals from a wheel
speed sensor that may indicate the need for ABS
intervention are questionable. When the brake pedal is
not pressed, the EBCM terminal 48 is grounded through
the stoplamps.
Diagnosis
This procedure will check whether there is no output or
constant output from the stoplamp switch and will deter-
mine the cause as a faulty switch or a problem in the
circuitry.Cause(s)
The ground connection or the positive connection
at the EBCM has failed.
There is an open, short to ground, or short to positive
in the vehicle wiring.
The stoplamp switch has failed.
Fail Action
The system records a DTC 27. ABS operation is not
dis-abled.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
12. This step begins the process of troubleshooting
stoplamps that are always on.
Diagnostic Aids
Inspect the wiring and the connectors carefully and
thoroughly. Failure to do so could result in misdiagnosis,
causing part replacement with the reappearance of the
malfunction.
