1100-LEFT FRONT WHEEL SPEED SENSOR CIRCUIT (CONTINUED)
When Monitored and Set Condition
• When Monitored (Supply circuit): Ignition on. The Controller Antilock Brake (CAB) monitors the wheel speed
circuit every 7 milliseconds (ms).
• When Monitored (Signal circuit): Wheel speed comparison is checked at drive off or every 7 milliseconds (ms).
Sensor Signal continuity is checked every 7 milliseconds. Wheel speed phase length supervision is checked
every 7 milliseconds.
• Set Condition (Supply circuit): If the CAB detects an open or shorted wheel speed sensor circuit, the Diag-
nostic Trouble Code (DTC) will set.
• Set Condition (Signal circuit): If, during an ABS stop, the CAB commands any valve solenoid on for an
extended length of time, and does not see a corresponding wheel speed change, the Diagnostic Trouble Code
(DTC) is set. The DTC can also set if the Signal is missing or erratic.
