  1. Turn ignition off. Disconnect negative battery cable. Using an ohmmeter, check resistance between ABS control unit harness connector terminals "O" and "L" while shaking harness between speed sensor and ABS control unit. See Figure .
  2. If resistance is a constant 1000-2000 ohms, go to next step. If resistance is erratic, repair loose connection in speed sensor leads. Check for dirty or loose terminals, frayed wires and shorted connectors.
  3. Remove speed sensor from differential and inspect for a build-up of metal chips on sensor magnetic pole. If no metal chips are present, go to next step. If metal chips are present, drain and clean differential. Check sensor rotor for broken or chipped teeth. Replace as necessary.
  4. Locate Blue 3-pin check connector in left side of engine compartment. See Figure . Position vehicle on a hoist and raise rear wheels from floor. Start engine and turn rear wheels at 5 MPH.
  5. Using voltmeter set on 2000 millivolt AC scale, measure voltage at terminals "B" and "C" of the check connector. See Figure . If voltage reading is greater than 210 millivolts at 3 MPH and 350 millivolts at 5 MPH, and steady, replace ABS control unit. If voltage reading is less than 210 millivolts at 3 MPH and 350 millivolts at 5 MPH, or erratic, go to next step.
  6. Remove speed sensor from differential. Rotate sensor rotor and check for damage to teeth. If teeth are intact and no visible lateral runout is observed, replace speed sensor and recheck output. If teeth are damaged or lateral runout of sensor rotor is visible, replace sensor rotor.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
