Test Description

WARNING: This page is about a different car, the 2007 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 3:  Measure the resistance of the wheel speed sensor in order to determine if the sensor has a valid resistance value.
  2. 4:  Ensures that the wheel speed sensor is generating a valid A/C voltage output.

3 
  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
  2. Disconnect the wheel speed sensor connector.
  3. Measure the resistance across the wheel speed sensor.
Does the resistance measure within the specified range?		 850-1350 Ω Go to Step 4  Go to Step 8 
4 
  1. Spin the wheel.
  2. Measure the A/C voltage across the wheel speed sensor.
Does the A/C voltage measure greater than the specified value?		 100 mV Go to Step 5  Go to Step 8 
5 Inspect for poor connections at the harness connector of the wheel speed sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 - Go to Step 10  Go to Step 6 
6 Test the wheel speed sensor circuits of the electronic brake control module (EBCM) for the following conditions:
  • An open
  • A short to ground
  • A short to voltage
  • Shorted together

Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 10  Go to Step 7 
7 Inspect for poor connections at the harness connector for the EBCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 - Go to Step 10  Go to Step 9 
8 Replace the wheel speed sensor. Refer to Wheel Bearing/Hub Replacement - Front in Front Suspension or Wheel Bearing/Hub Replacement - Rear .
Did you complete the replacement?		 - Go to Step 10  -
9 Replace the EBCM. Refer to Control Module References for replacement, setup, and programming.
Did you complete the repair?		 - Go to Step 10  -
