4F-66 ABS AND TCS
DIAGNOSTIC TROUBLE CODE (DTC) 17/18
LEFT REAR INLET AND OUTLET VALVE SOLENOID FAULT
KAA4F200
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 left rear inlet and
outlet valves are functioning.
Cause(s)
A valve has failed.
A solenoid coil is open or shorted.Fail Action
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. his tests the outlet valve.

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 front 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.

LEFT REAR PRIME LINE AND TRACTION CONTROL
SYSTEM (TCS) PILOT VALVE FAULT
KAA4F200
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 left rear TCS valves
are functioning.Cause(s)
A solenoid coil is open or shorted.
Fail Action
Antilock brake system (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.
