Circuit/System Testing

2013 Chevrolet Equinox LS, AWD, GasSECTION Circuit/System Testing
  1. Ignition OFF, disconnect the X2 harness connector at the K73 Telematics Communication Interface Control Module.
  2. Test for less than 10 Ω between the low reference circuit terminal 12 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the X4 harness connector at the A11 Radio.
    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 A11 Radio.
    • If less than 10 Ω 
  3. Ignition ON, radio ON.
  4. Test for less than 1 V between the signal circuit terminal 6 and ground.
    • If 1 V greater 
    1. Ignition OFF, disconnect the X4 harness connector at the A11 Radio. 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 A11 Radio.
    • If less than 1 V 
  5. Ignition OFF, disconnect the X4 harness connector at the A11 Radio.
  6. Test for infinite resistance between the circuits listed below and ground:
    • voice recognition signal circuit A11 Radio X4 terminal 6
    • voice recognition low reference circuit A11 Radio X4 terminal 16
    • If less than infinite resistance 

      Repair the short to ground on the circuit.

    • If infinite resistance 
  7. Test for less than 5 Ω between the terminals listed below:
    • A11 Radio X4 terminal 6 and the K73 Telematics Communication Interface Control Module X2 terminal 6
    • A11 Radio X4 terminal 16 and the K73 Telematics Communication Interface Control Module X2 terminal 12
    • If 5 Ω greater 

      Repair the open/high resistance in the circuit.

    • If less than 5 Ω 
  8. Replace the A11 Radio. Connect all harness connectors.
    9. NOTE:

    Refer to the Navigation System Owners Manual for voice recognition use and commands.

  9. Begin voice recognition for the radio and clearly speak one of the available commands.
  10. Verify the infotainment system responds correctly to the command.
    • If the infotainment system does not respond correctly to the command 
    1. Clearly speak a different command.
    2. Verify the infotainment system responds correctly to the command.
      • If the infotainment system does not respond correctly to any commands, replace the K73 Telematics Communication Interface Control Module.
    • If the infotainment system responds correctly to the command 
  11. 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.
