4F-68 ABS AND TCS
DIAGNOSTIC TROUBLE COED (DTC) 19/20 - RIGHT REAR INLET AND
OUTLET VALVE SOLENOID FAULT
Circuit Description
The solenoid valve coil circuits are supplied with power
from the battery when the valve relay is energized.
Switched ground is provided by the electronic brake
control module (EBCM) to each coil.
Diagnosis
This procedure checks whether the right rear inlet and
outlet valves are functioning.
Cause(s)
A valve has failed.
A solenoid coil is open or shorted.Action Taken When the DTC Sets
ABS is disabled, and the ABS warning lamp is turned
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.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This begins the test of the inlet valve
3. This tests the outlet valve.

Step
1. Raise and suitably support the vehicle.
2. Turn the ignition to ON.
3. Install the scan tool to the data link connector
(DLC) and select “Wheel rear right” to begin the
solenoid tests at that wheel. This will test both the
inlet and the outlet valves.
4. When the scan tool indicates “Pressure hold”,
press and hold the brake pedal until the end of the
test.
5. Have an assistant attempt to rotate the wheel.
Can the wheel be rotated?
1. Maintain pressure on the brake pedal.
2. When the scan tool indicates “Pressure increase”,
have an assistant attempt to rotate the wheel
again.
Can the wheel be rotated now?
1. Maintain pressure on the brake pedal.
2. When the scan tool indicates “Pressure release
on”, have an assistant attempt to rotate the wheel
again.
Can the wheel be rotated?
1. Release brake pedal pressure when the scan tool
indicates “Pressure release off”.
2. Clear all DTCs.
3. Road test the vehicle.
Does the DTC set again?
1. Check the wiring harness and connector terminals
for an intermittent problem.
2. Repair any problem found.
Is the repair complete?
Replace the ABS unit.

attempt to rotate the wheel.
Can the wheel be rotated?
When the scan tool indicates that the prime valve
was turned OFF, attempt to rotate the wheel again.
Can the wheel be rotated now?
When the scan tool indicates that the pilot valve and
the pump motor were switched OFF, attempt to rotate
the wheel again.
Can the wheel be rotated?
1. Clear all the DTCs.

DIAGNOSTIC TROUBLE CODE (DTC) 12
VALVE RELAY CIRCUIT FAULT
KAA4F210
Circuit Description
When the ABS is active, the valve relay provides voltage
to actuate the solenoid valves. The valves do not use
this voltage unless the ABS control module provides
the ground for each solenoid coil.
DTC 12 will set if the valve relay voltage is low or if the
relay supply line is at 12 volts when the ABS control
module is not requesting it. This DTC will also set if the
ABS control module detects three or more solenoid
valve circuits are open or shorted during the self-test.
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 wiring harness is damaged.
The ground terminal is not conducting properly.
The valve relay is defective.
The EBCM is defective.
Fail Action
ABS/TCS is disabled, and the ABS warning lamp is
turned ON for the remainder of the ignition cycle. If the
failure is intermittent, the control module will enable
the system at the next ignition cycle and set a history
DTC 12.
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) 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.
