Input Signal Check Mode

WARNING: This page is about a different car, the 2006 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

Input signal check mode allows testing of switch input signal to the back door control unit.

To activate input signal check mode on the automatic back door, perform the following steps:

  1. Turn ignition switch OFF.
  2. Turn back door close switch to CANCEL (system cancelled).
  3. Place A/T selector lever in P position.
  4. Using the inside emergency release lever, open the back door.
  5. Have an assistant press and hold the back door handle switch.
  6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start engine).
  7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
  8. Release the back door handle switch.
  9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
  10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
  11. Release the power liftgate switch.
  12. The input signal check mode is now initialized.

The input signal check mode can test the following inputs. The back door warning chime will sound for approximately 0.5 seconds each time a switch signal input occurs. Use this test when one of these inputs is not responding during normal automatic back door operation.
