and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
^
check that the program card is correctly installed.
^
check the connections to the vehicle.

If the diagnostic tool responds with:
^
CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network (Information Bus).
