Circuit/System Testing

WARNING: This page is about a different car, the 2011 GMC Cab & Chassis Sierra, 2011 Chevrolet Suburban, and 2011 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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.
  2. Test for less than 20 Ω between the low reference circuit terminal 2 and ground.
    • If 20 Ω or greater 
    1. Ignition Off, disconnect the harness connector at the EBCM.
    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 EBCM.
    • If less than 20 Ω 
  3. Ignition ON.
  4. 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 EBCM.
    2. Test for infinite resistance between 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 to less than 2 Ω in the 5 V reference circuit end to end.
      • If 2 Ω for greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the EBCM.
    • If greater than 5.2 V 
    1. Ignition OFF, disconnect the harness connector at the EBCM, ignition ON.
    2. Test for less than 1 V between the 5 V reference circuit terminal 1 and ground
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the EBCM.
    • If between 4.8-5.2 V 
  5. Test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and the signal circuit terminal 6.
    • If less than 4.8 V 
    1. Ignition OFF, disconnect the harness connector at the EBCM.
    2. Test for less than 2 Ω in the signal circuit end to end.
      • If greater than 2 Ω, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the EBCM.
    • If greater than 5.2 V 
    1. Ignition OFF, disconnect the harness connector at the EBCM, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If greater than 1 V, repair the short to voltage on the circuit.
      • If less than 1 V, replace the EBCM.
    • If between 4.8-5.2 V 
  6. Ignition OFF, disconnect the harness connector at the EBCM.
  7. Test for infinite resistance between the signal circuit terminal 9 and ground.
    • If less than infinite resistance 

      Repair the short to ground on the circuit.

    • If infinite resistance 
  8. Connect the harness connector at the EBCM.
  9. Ignition ON.
    10. NOTE:

    When measuring voltage at the steering angle sensor harness connector, the voltage values are based on a battery charge of 12.5 V and the steering wheel is in the center position.

  10. Test for 6.8-11.7 V between the signal circuit terminals listed below and ground with the steering wheel in the center position.
    • Terminal 3
    • Terminal 4
    • Terminal 5
    • If less than 6.8 V 
    1. Ignition OFF, disconnect the harness connector at the EBCM.
    2. Test for infinite resistance between the signal 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 on the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the EBCM.
    • If greater than 11.7 V 
    1. Ignition OFF, disconnect the harness connector at the EBCM, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the EBCM.
    • If between 6.8-11.7 V 
  11. Test or replace the steering angle sensor.
