2005 Saturn Relay AWDFACTORY OEM SERVICE PROCEDURE

Test Description

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 AC voltage output.
DTC C0035-C0052

Step Action Values Yes No
Schematic Reference: ABS Schematics 
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  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 in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 10  Go to Step 6 
6
  1. Disconnect the electronic brake control module (EBCM) harness connector.
  2. Test the wheel speed sensor circuits for the following:
    • An open
    • A short to ground
    • A short to voltage
    • Shorted together
Refer to Circuit Testing and Wiring Repairs in Wiring Systems.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 in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 10  Go to Step 9 
8 Replace the wheel speed sensor. Refer to the appropriate procedure:
Did you complete the replacement?		 - Go to Step 10  -
9 Replace the EBCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
Did you complete the replacement?		 - Go to Step 10  -
10
  1. Use the scan tool in order to clear the DTCs.
  2. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
Does the DTC reset?		 - Go to Step 2  System OK
