STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
Phenomenon Explanation
System check sound When starting the engine, a thudding sound can sometimes be heard coming
from inside the engine compartment. This is because the system operation check
is being performed.
ABS operation sound a.Sound of the motor inside the ABS hydraulic unit operation (whine).
b. Sound is generated along with vibration of the brake pedal (scraping).
c. When ABS operates, sound is generated from the vehicle chassis due to
repeated brake application and release
(Thump : suspension; squeak: tires)
ABS operation (Long braking
distance) For road surfaces such as snow- covered and gravel roads, the braking distance
for vehicles with ABS can sometimes be longer than that for other vehicles.
Accordingly, advise the customer to drive safely on such roads by lowering the
vehicle speed.
Diagnosis detection conditions can vary depending on the diagnosis code. When checking the trouble symptom after
the diagnosis code has been erased, ensure that the requirements listed in "Comment" are met.
SCAN TOOL (PRO) CHECK
1. Turn the ignition switch OFF.
2. Connector the Scan tool to the 16P data link connector located the driver's side kick panel.

c.Stop lamp switch circuit.
d. Check the hydraulic circuit for leakage.
Communication with Scan tool is not possible.
(Communication with any system is not possible) a.
Power source circuit
b. Diagnosis line
Communication with Scan tool is not possible.
(Communication with ABS only is not possible) a.
Power source circuit
b. Diagnosis line
c. HECU
When ignition key is turned ON (engine OFF), the ABS
warning lamp does not light up. a.
ABS warning lamp circuit
b. HECU
Even after the engine is started, the ABS warning lamp
remains ON. a.
ABS warning lamp circuit
b. HECU
During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such phenomena are
due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking and is
not an abnormality.
DETECTING CONDITION
Trouble Symptoms Possible Cause
Brake operation varies depending on driving conditions and road
surface conditions, so diagnosis can be difficult.However if a normal
DTC is displayed, check the following probable cause. When the
problem is still occurring, replace the ABS control module. a.
Inoperative power source circuit
b. Inoperative wheel speed sensor circuit
c. Inoperative hydraulic circuit for leakage
d. Inoperative HECU
INSPECTION PROCEDURES

connector and body ground.
Specification: approximately B+
Is the voltage within specification?
▶ Check the ground circuit.
▶ Check the harness or connector between the fuse (10A) in the engine compartment junction block and the ABS
control module. Repair if necessary.

control module. Repair if necessary.
CHECK THE GROUND CIRCUIT.
1.Disconnect the connector from the ABS control module.
2. Check for continuity between terminals 1,4 of the ABS control module harness side connector and ground point.
Is there continuity?
▶ Check the wheel speed sensor circuit.
▶ Repair an open in the wire and ground point.
CHECK THE WHEEL SPEED SENSOR CIRCUIT.
Refer to the DTC troubleshooting procedures.
Is the system operating to specifications ?
▶ Check the hydraulic circuit for leakage.
▶ Repair or replace the wheel speed sensor.
CHECK THE HYDRAULIC CIRCUIT FOR LEAKAGE.
Refer to the hydraulic lines.
Inspect leakage of the hydraulic lines.
Is the system operating to specifications ?
▶ The problem is still occurring, replace the ABS control module.
▶ Replace the leaking hydraulic lines.
DETECTING CONDITION
Trouble Symptoms Possible Cause
Brake operation varies depending on driving conditions and road
surface conditions, so diagnosis can be difficult.However if a normal
DTC is displayed, check the following probable cause. When the a.
Inoperative power source circuit
b. Inoperative wheel speed sensor circuit

DTC is displayed, check the following probable cause. When the
problem is still occurring, replace the ABS control module.b.
Inoperative wheel speed sensor circuit
c. Inoperative hydraulic circuit for leakage
d. Inoperative HECU
INSPECTION PROCEDURES
DTC INSPECTION
1. Connect the Scan Tool with the data link connector and turn the ignition switch ON.
2. Verify that the system is operating to specifications.
Is the system operating to specifications ?
▶ Check the wheel speed sensor circuit.
▶ Erase the DTC and recheck using Scan Tool.
CHECK THE WHEEL SPEED SENSOR CIRCUIT.
Refer to the DTC troubleshooting procedures.
Is the system operating to specifications ?
▶ Check the stop lamp switch circuit.
▶ Repair or replace the wheel speed sensor.
CHECK THE STOP LAMP SWITCH CIRCUIT.
1. Check that stop lamp lights up when brake pedal is depressed and turns off when brake pedal is released.
2. Measure the voltage between terminal 20 of the ABS control module harness side connector and body ground
when brake pedal is depressed.
Specification: approximately B+
Is the voltage within specification?
▶ Check the hydraulic circuit for leakage.
▶ Repair the stop lamp switch. Repair an open in the wire between the ABS control module and the stop lamp
switch.
CHECK THE HYDRAULIC CIRCUIT FOR LEAKAGE.
Refer to the hydraulic lines.
Inspect leakage of the hydraulic lines.
Is the system operating to specifications ?
▶ The problem is still occurring, replace the ABS control module.

CHECK FOR BLOWN FUSE
Check continuity of fuse (10A) from the engine compartment junction block.
Is there continuity?
▶ Repair an open in the wire between ABS fuse and 1 of cluster connector.
▶ Replace the blown fuse.
DETECTING CONDITION
Trouble Symptoms Possible Cause
If the HECU detects trouble, it lights the ABS warning lamp while at
the same time prohibiting ABS control. At this time, the HECU
records a DTC in memory.Even though the normal code is output, the
ABS warning lamp remains ON, then the cause may be probably an
open or short in the ABS warning lamp circuit. a.
An open in the wire
b. Inoperative instrument cluster assembly
c. Inoperative ABS warning lamp module
d. Inoperative HECU
INSPECTION PROCEDURES
CHECK DTC OUTPUT.
1. Connect the Scan Tool to the 16P data link connector located behind the driver's side kick panel.
2. Check the DTC output using Scan Tool.
Is DTC output ?
▶ Repair circuit indicated by code output.
▶ Check instrument cluster.
CHECK INSTRUMENT CLUSTER
Disconnect the cluster connector and turn the ignition switch ON.
Does the ABS warning lamp remains ON?
▶ Replace the instrument cluster.
▶ Check for open the wire.
CHECK FOR OPEN IN THE WIRE
Check for continuity in the wire between cluster and ABS control module.
Is there continuity?
▶ Replace the ABS control module and recheck.
▶ Repair an open in the wire between cluster and ABS control module.
BLEEDING OF BRAKE SYSTEM
1. Remove the reservoir cap and fill the brake reservoir with brake fluid.
If there is any brake fluid on any painted surface, wash it off immediately.

When pressure bleeding, do not depress the brake pedal.
Recommended fluid........ DOT3 or DOT4
2. Connect a clear plastic tube to the brake caliper bleeder plug and insert the other end of the tube into a half filled
clear plastic bottle.
3.Connect the scan tool to the data link connector located underneath the dash panel.
4.Select and operate according to the instructions on the scan tool screen.
You must obey the maximum operating time of the ABS motor with the scan tool to prevent the motor pump
from burning.
(1) Select kia vehicle diagnosis.
(2) Select vehicle name.
(3) Select Anti- Lock Brake system.
(4) Select air bleeding mode.
(5) Press "YES" to operate motor pump and solenoid valve.

(6)Wait 60 sec. before operating the air bleeding again. (If not, you may damage the motor.)
5.Pump the brake pedal several times, and then loosen the bleeder screw until fluid starts to run out without bubbles.
Then close the bleeder screw.
6. Repeat step 5 until there are no more bubbles in the fluid for each wheel.
7.Tighten the bleeder screw.
Bleed screw tightening torque:
7~1 3 Nm (0.7 ~1.3 kgf·m, 5.06 ~ 9.4 lb - ft)
