Turn the ignition switch ON (II).
Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to the DLC circuit troubleshooting, '04-06 models (see '04-06 MODELS ), '07-08 models (see '07-08 MODELS ).
Select the INSPECTION MENU with the HDS.
Do the TP POSITION CHECK in the ETCS TEST. If needed, clean the throttle body (see THROTTLE BODY CLEANING ).
