NOTE
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, clear DTC once referring to “DTC
Clearance” and then performing the driving test as described in Step 2 of “Electronic Stability Program
System Check”, check whether or not any abnormality exists.
• The vehicle was driven with parking brake pulled.
• Wheel spin occurred while driving.
• Wheel(s) was turned while the vehicle was jacked up.
