Circuit/System Testing

2013 Chevrolet Corvette Base, 2D Convertible, Standard Trans, Trans Mfr CD 6L85M/MM6SECTION Circuit/System Testing
IMPORTANT:

It is recommended that Component Testing is performed before Circuit/System Testing when diagnosing the VES actuator because the module will default and does not supply voltage to the sensor when the DTC is set.

  1. Ignition OFF, disconnect the harness connector at the VES actuator.
    IMPORTANT:

    In order to ensure correct test results, the J-35616 test lamp must be used to perform the following steps. Failure to use the J-35616 test lamp may result in inaccurate test results and potential misdiagnosis.

  2. Ignition ON, verify that a test lamp illuminates between the control circuit terminal A and ground.
    • If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance.
  3. Ignition OFF, connect the test lamp between the control circuit terminal A and the control circuit terminal B.
  4. Ignition ON, verify the test lamp briefly illuminates for approximately 1 second, then turns OFF.
    • If the test lamp is always ON, test the control circuit terminal B for a short to ground. If the circuit tests normal, replace the EBCM.
    • If the test lamp is always OFF, test the control circuit terminal B for a short to voltage or an open/high resistance. If the circuit tests normal, replace the EBCM.
  5. If all circuits test normal, test or replace the VES actuator.

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.
