DESCRIPTION
The ABS control module monitors the voltage at the positive (+) terminal of each sensor while the ignition switch
is ON. When the voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal
is inputted at starting or while running, an applicable DTC will be set.
NOTE:
When the vehicle was operated in any of the following ways, one of these DTC's may be set even when
the sensor is in good condition. If such possibility is suspected, repair the trouble (dragging of brake, etc.)
of the vehicle, clear DTC once and then after performing the driving test as described in Step 2 of ªABS
DIAG. FLOW TABLEº, check whether or not any abnormality exists.
± The vehicle was driven with parking brake pulled.
± The vehicle was driven with brake dragging.
± Wheel spin occurred while driving.
± Wheel(s) was turned while the vehicle was jacked up.
± The vehicle was stuck.
