SH-AWD® Control Unit Initialization

Whenever the SH-AWD control unit is replaced, it must be initialized.

  1. With the ignition switch in LOCK (0), connect the HDS to the DLC (A) located under the driver's side of the dashboard.

  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with vehicle and the SH-AWD control unit. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  4. From the mode menu, select MISCELLANEOUS TEST, then select INITIALIZATION with the HDS and follow the screen prompts.
    NOTE: See the HDS help menu for specific instructions.
