DTC Detecting Condition
The ABS (ESP®) control module monitors the current at the terminal of each sensor while the ignition switch is ON.
When the current is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is
inputted at running, an applicable DTC will be set.
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

whether or not any abnormality exists.
