Circuit/System Testing

2011 GMC Savana G2500, Van Cargo, 6.0 GSECTION Circuit/System Testing
  1. Ignition ON.
  2. Verify that DTC U0137, U0186, U1827 or C0710 are not set.
    • If none of the DTCs are set 
  3. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the steering angle sensor. It may take up to 2 minutes for all vehicle systems to power down.
  4. Test for less than 10 Ω between the low reference circuit terminal 2 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the electronic brake control module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the electronic brake control module.
    • If less than 10 Ω 
  5. Ignition ON.
  6. Test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and ground.
    • If less than 4.8 V 
    1. Ignition OFF, disconnect the harness connector at the electronic brake control module.
    2. Test for infinite resistance in the 5 V reference circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the 5 V reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the electronic brake control module.
    • If greater than 5.2 V 
    1. Ignition OFF, disconnect the harness connect at the electronic brake control module, ignition ON.
    2. Test for less than 1 V between the 5 V reference circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the electronic brake control module.
    • If between 4.8-5.2 V 
  7. Ignition OFF, disconnect the harness connector at the electronic brake control module.
  8. Test for infinite resistance between the signal circuit terminal 6 and ground.
    • If less than Infinite resistance 

      Repair the short to ground on the circuit.

    • If Infinite resistance 
  9. Connect the harness connector at the electronic brake control module and disconnect the harness connector at the yaw and lateral accelerometer sensor.
  10. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down.
  11. Test for less than 10 Ω between the low reference circuit terminal 6 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the electronic brake control module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the electronic brake control module.
    • If less than 10 Ω 
  12. Ignition ON.
  13. Verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.
    • If the test lamp does not illuminate 
    1. Ignition OFF, disconnect the harness connector at the electronic brake control module.
    2. Test for infinite resistance between the ignition circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the ignition circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the electronic brake control module.
    • If the test lamp illuminates 
  14. Replace the yaw and lateral accelerometer sensor.
  15. Verify the DTC does not set while operating the vehicle under the Conditions for Running the DTC.
    • If the DTC sets 

      Replace the steering angle sensor.

    • If the DTC does not set 
  16. All OK.

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.
