Kia Sedona (2008 year). Instruction — part 13

MONITOR SCAN TOOL DATA

1. Engine "ON".

2. Connect scan tool to Data Link Connector (DLC).

3. Start and drive vehicle in gear and maintain vehicle speed at or above 12km/h (7 mph).

4. Monitor the "Wheel speed sensor" parameter on the scan tool.

Specification: Approx. 12 km/h or more (7 mph or more)

Case1

ABS-control is active
at a front wheel and a
rear wheel.



Improper installation
of wheel speed
sensor



Abnormal Rotor and
wheel bearing



Inoperative Wheel
speed sensor



Inoperative HECU

Enable Conditions



Every time, if a gap in
the wheel speed sensor
signal occurs
cyclically with one
wheel rotation, a fault
counter is increased by
one. If the fault
counter exceeds its
limit of 10 V, a wheel
specific fault is stored
in the EEPROM.

Case2

Monitoring Period



Continuous

Enable Conditions



If following
interference and signal
disturbance is
detected, a failure is
set after 10 s.

non-plausible high
frequency received.

non-plausible high
wheel acceleration.

non-plausible high
wheel jerk.

non-plausible delta T
and edges at low
speed.

Fail Safe

Refer to DTC C1200.

5. 5 Is parameter displayed within specifications?

YES



Fault is intermittent caused by poor connection in wheel speed sensor harness and/or HECU's
connector or was repaired and HECU memory was not cleared Go to "COMPONENT
INSPECTION" procedure

NO



Check for improper installation of wheel speed sensor If NG, repair as necessary and then go to
"VERIFICATION OF VEHICLE REPAIR" procedure



Check for damage of rotor teeth or wheel bearing If NG, repair as necessary and then go to
"VERIFICATION OF VEHICLE REPAIR" procedure



Substitute with a known-good Wheel speed sensor and check for proper operation If problem is
corrected, replace Wheel speed sensor and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure



If OK, Go to "COMPONENT INSPECTION" Procedure

COMPONENT INSPECTION

1. Ignition "OFF".

2. Engine "ON".

3. Start and drive vehicle in gear and maintain vehicle speed at or above 12 km/h(7 mph).

4. Does warning lamp remain On?

YES



Substitute with a known-good HECU and check for proper operation. If problem is corrected,
replace HECU and then go to "VERIFICATION OF VEHICLE REPAIR" procedure.

NO



Fault is intermittent caused by open or short of wheel speed sensor harness, inoperative wheel
speed sensor. Go to the applicable troubleshooting procedure.

VERIFICATION OF VEHICLE REPAIR

After a repair, it is essential to verify that the fault has been corrected.

1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode

2. Using a scan tool, Clear DTC.

3. Operate the vehicle within DTC Detecting Condition in General Information. Start and drive vehicle in

gear and maintain vehicle speed at or above 12 km/h (7 mph).

4. Are any DTCs present?

YES



Go to the applicable troubleshooting procedure.

NO



System performing to specification at this time.

SENSOR-OPEN/SHORT; DTC C1206 RL WHEEL SPEED SENSOR-OPEN/SHORT; DTC C1209 RR
WHEEL SPEED SENSOR-OPEN/SHORT.

DTC DESCRIPTION

The ABS ECU monitors the wheel speed sensor signal continuously. This code is set when there is no wheel
speed signals within 10 ms to 20 ms at a vehicle speed > 43.2 km/h or a deviation between sensors exceed the

Signal monitoring

Case1

Monitoring Period



Continuous (only no under
voltage is not detected)

Enable Conditions



If one (or two) wheel are at 2.75
km/h and the other wheels are
above 12 km/h for longer than
1s.



During driving, when the vehicle
accelerates 18 km/h after a
particular wheel speed gets to
2.75 km/h and stays there. At
that time, If one (or two) wheel
are at 2.75 km/h.



This monitoring is
performed at the following
condition.

1. At the time the vehicle is

accelerated to 12 km/h

2. Once after energizing the

system.

3. If the vehicle was

stationary for approx. 2 s.



If one (or two) wheels are under
5 km/h and the two fastest
wheels have a velocity above 12
km/h for more than 20 s.

Monitoring Period

but this monitoring is
disabled in the following
event

1. aquaplaning.

2. interference.

3. supply voltage below 7.6
