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. Thoroughly check connectors for 
looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or 
replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

NO  



Go to TERMINAL & CONNECTOR INSPECTION procedure.  

TERMINAL & CONNECTOR INSPECTION

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 10km/h (6 mph).  

4. Are any DTCs present? 

YES  



Go to the applicable troubleshooting procedure.  

NO  



RANGE/PERFORMANCE; DTC C1207 RL WHEEL SENSOR-RANGE/PERFORMANCE; DTC 
C1210 RR WHEEL SENSOR-RANGE/PERFORMANCE 

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 when an abnormal signal 
due to air gap problem or an abnormal speed change ratio are detected at the vehicle speed between 10 km/h to 
80 km/h. Warning lamp is turned OFF unless additional faults are detected when the IG KEY is turned ON 
again, and wheel speed is more than 12 Km/h.
