Test 5A: Left Front Sensor Signal Failure

NOTE: After each repair, perform TEST VER-1A: VERIFICATION TEST  to confirm problem has been corrected.
  1. With assistant driving vehicle, use scan tool to observe all Wheel Speed Sensors (WSS). Slowly accelerate as straight as possible from a stop to 15 MPH. If Left Front (LF) WSS shows zero MPH or lags behind any other WSS more than 3 MPH, go to next step. If LF WSS does not show zero MPH or lag behind any other WSS more than 3 MPH, go to step  6 .
  2. Turn ignition off. Inspect LF WSS and connector for obvious damage. Repair as necessary. If WSS and connector are okay, go to next step.
    3. NOTE: Tone wheel teeth should be perfectly square, not bent or nicked. Tone wheel is pressed into axle shaft. Replacement of tone wheel requires replacement of axle shaft.
  3. Inspect tone wheel for damaged or missing teeth, or looseness. Tighten or replace as necessary. If tone wheel is okay, go to next step.
  4. Using feeler gauge, measure air gap between end of LF WSS and teeth on tone wheel at 4 different places on tone wheel. Air gap should be .017-.067" (.42-1.71 mm). If air gap is within specification, go to next step. If air gap is not within specification, repair or replace components as necessary.
  5. Inspect LF wheel bearings for excessive runout or clearance. If no excessive wheel bearing runout or clearance exists, test is complete. If excessive wheel bearing runout or clearance exists, repair as necessary.
  6. Conditions required to set Diagnostic Trouble Code (DTC) are not present at this time. DTC may have set by attempting to stop on very slippery road surface, or by brakes locking up due to lining contamination or overheating. Check if any of these conditions are present. Repair as necessary. If these conditions are not present, go to next step.
    7. NOTE: Front tone wheel is pressed into front axle shaft. Replacement of front tone wheel requires replacement of front axle shaft.
  7. Visually inspect WSS and tone wheel for obvious damage. Replace tone wheel and/or WSS as necessary. See FRONT WHEEL SPEED SENSOR  under REMOVAL & INSTALLATION. If tone wheel and WSS are okay, go to next step.
  8. Using wiring diagram as a guide, inspect ABS wiring and connectors. See WIRING DIAGRAMS  . Repair problems as necessary. If no problems are found, test is complete.
