Kia Sedona (2008 year). Instruction — part 14

Case2

Enable Conditions



No wheel speed signals within
10 ms to 20 ms at a vehicle
speed > 12 m/s (43.2 km/h ).



If the dynamic sensor
monitor responses, the
failures will be stored into
failure memory
immediately after a
waiting period of 60 ms.



If occurs low voltage
active sensors during the
waiting period of 60 ms no
failure is stored in the
EEPROM.

Case3

Monitoring Period



Main Monitoring The main
monitor needs additional
information of the ESC-sensors
and is active for a velocity > 20
km/h and no under voltage is
detected.



Backup Monitoring



Continuous

Enable Conditions



Main Monitoring

1. If the maximum difference

of wheel speeds related to
maximum wheel speed
exceeds 5%.

2. detection filter time:



the above conditions
apply for 20 s for 1
inoperative wheel
speed sensor.



the above conditions
apply for 40 s for 2
inoperative wheel
speed sensor.



Backup Monitoring

1. If the deviation between

the fastest and the slowest
wheel is below 6 % related
to the fastest wheel when
the velocity is higher than
50 km/h.

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 50 km/h (31 mph).

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

Specification: Approx. 50 km/h or more (31 mph or more)

2. When the velocity is

below 50 km/h, if the
deviation is an absolute
value of 3 km/h.

3. detection filter time:

normally 20 s



In case of a detected
curve, the threshold
is increased with an
additional value of 4
km/h.



Improper
installation of
wheel speed
sensor



Abnormal Rotor
and wheel
bearing



Inoperative
Wheel speed
sensor



Inoperative
HECU

Case4

Monitoring Period



Continuous

Enable Conditions



The pulse width of wheel speed
sensor is below 2 ms when
vehicle speed is > 0km/h and <
20 km/h.

Case5 (ABS only)

Monitoring Period



Continuous

Enable Conditions



If there are differences between
each wheel and if the exact fault
location can be determined when
the faulty wheel speed is at or
below 5 km/h.

Fail Safe

Refer to DTC C1200.

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 50 km/h(31 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 50 km/h (31 mph).

4. Are any DTCs present?

YES



Go to the applicable troubleshooting procedure.

NO



System performing to specification at this time.

DTC C1213 WHEEL SPEED FREQUENCY ERROR

COMPONENT LOCATION

Refer to DTC C1200.

GENERAL DESCRIPTION

Refer to DTC C1200.

DTC DESCRIPTION

The ABS ECU monitors the wheel speed sensor signal continuously. This code is set, if the speed difference
with adjacent wheel is out of permissible range or the control cycle is abnormal.
