Circuit/System Testing

2006 Pontiac G6 GTP, 2D Coupe, StandardSECTION Circuit/System Testing
WARNING: This page is about a different car, the 2012 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Circuit/System Verification must be performed before Circuit/System Testing. The testing listed below is for the external Steering Wheel Position Sensor. Refer to DTC C0460 for the internal Position Steering Angle Sensor diagnostics.

  1. Ignition OFF, disconnect the harness connector at the Steering Wheel Position Sensor.
  2. Ignition OFF for 60 seconds, test for less than 10 Ξ© between the low reference circuit terminal 2 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the Electronic Brake Control Module.
  3. Disconnect the harness connector at the Electronic Brake Control Module.
  4. Test for less than 1 V between the 5 V reference circuit terminal 1 and ground.
    • If greater than the specified range, test the 5 V reference circuit for a short to voltage.
  5. Ignition OFF, test for infinite resistance between the 5 V reference circuit terminal 1 and ground.
    • If less than the specified value, test the 5 V reference circuit for a short to ground.
  6. Ignition OFF, test for less than 2 Ξ© between the 5 V reference circuit terminal 1 at the Steering Wheel Position Sensor harness connector and terminal 31 at the Electronic Brake Control Module harness connector.
    • If greater than the specified range, test the 5 V reference circuit for an open/high resistance.
  7. Ignition ON, test for less than 1 V between the signal circuits listed below and ground.
    • Steering Wheel Position Signal A terminal 5
    • Steering Wheel Position Signal B terminal 6
      • If greater than the specified range, test the signal circuit for a short to voltage.
  8. Ignition OFF, test for infinite resistance between the signal circuit listed below and ground.
    • Signal A terminal 5
    • Signal B terminal 6
      • If less than the specified value, test the signal circuit for a short to ground.
  9. Test for less than 2 Ξ© between the signal circuit terminals listed below.
    • Signal A terminal 5 at the Steering Wheel Position Sensor harness connector and terminal 8 at the Electronic Brake Control Module harness connector.
    • Signal B terminal 6 at the Steering Wheel Position Sensor harness connector and terminal 20 at the Electronic Brake Control Module harness connector.
      • If greater than the specified range, test the signal circuit for an open/high resistance.
  10. If all circuits test normal, replace the Steering Wheel Position Sensor. If the DTC resets replace the Electronic Brake Control Module.

When to See a Mechanic

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

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