    • If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal. replace the A23D door latch assembly-driver.
  3. Verify that a test lamp does not illuminate between the control circuit terminal 10 and ground.
    • If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, replace the A23D door latch assembly-driver.
  4. Test for infinite resistance between the control circuit terminal 5 and ground.
    • If not the specified value, test the control circuit for a short to ground. If the circuit tests normal. replace the A23D door latch assembly-driver.
  5. Test for infinite resistance between the control circuit terminal 10 and ground.
    • If not the specified value, test the control circuit for a short to ground. If the circuit tests normal. replace the A23D door latch assembly-driver.
