Scan tool does not power up (4JJ3 with DPD)

The DLC is a standardized 16-pole connector. Connector design and location are dictated by an industry-wide standard and are required to provide the following.

  • The battery voltage of the scan tool power supply is terminal 16.
  • The scan tool power supply ground is terminal 4.
  • The common signal ground is terminal 5.

The scan tool powers up when the ignition switch is OFF, but some modules will not communicate unless the ignition switch is ON.
