Kia Sedona (2008 year). Manual - 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.
