DIAGNOSTIC TROUBLE CODE (DTC) 28
LOW VOLTAGE FAULT
KAA4F240
Circuit Description
Proper operation of the electronic brake control module
(EBCM) requires a certain minimum voltage. The EBCM
monitors the ignition feed circuit to determine if the
voltage falls below a minimum level.
Diagnosis
This test checks for battery output, proper grounding,
blown fuses, faulty ignition switch, and problems in the
circuitry.
Cause(s)
The battery is defective.
There is a defective ground connection.
A connector is damaged.
A wire is broken or shorted.
A fuse is blown.
The ignition switch is malfunctioning.Fail Action
ABS action is disabled during the period of low voltage,
and the ABS warning lamp is ON for the remainder of
the ignition cycle. If the failure is intermittent, the EBCM
will enable the system at the next ignition cycle and
set a history DTC 28.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This step determines whether there is voltage at
the battery and at the high current source.
7. This step checks for voltage at the ignition 1
source.
15. This step begins the check for voltage at the EBCM
end of the ABS harness.
Diagnostic Aids
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to do so may re-
sult in misdiagnosis, causing part replacement with the
reappearance of the malfunction.

DIAGNOSTIC TROUBLE CODE (DTC) 02
ABS CONTROL MODULE INTERNAL FAULT
KAA4F240
Circuit Description
The ABS control module performs various diagnostic
checks on itself. If it finds a problem, it sets DTC 02.
Diagnosis
This procedure checks whether there is a poor ground
connection for the electronic brake control module
(EBCM).
Cause(s)
A connector terminal is corroded.
The EBCM is malfunctioning.
Fail Action
ABS is disabled, and the ABS warning lamp is turned
ON. If the failure is intermittent, the control module will
enable the system at the next ignition cycle and will
store a history DTC 02.Test Description
The number(s) below refer to step(s) on the diagnostic
table.
3. This step begins the testing for a poor voltage or
ground connection.
Diagnostic Aids
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.
