Kia Sedona (2008 year). Manual - 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.
