  • If the certification ECU (smart key ECU assembly) or transmission control ECU assembly is replaced, refer to Registration. Refer to REGISTRATION .
  • When using the Techstream to troubleshoot with the power switch off:

    Connect the Techstream to the DLC3, and turn the courtesy switch on and off at 1.5-second intervals until communication between the Techstream and vehicle begins.
