INSPECTION PROCEDURE
1.
Turn ignition switch OFF.
2.
Connect CONSULT-II to data link connector, which is located
under the driver side dash panel.
3.
Turn ignition switch ON.
4.
Touch “START (NISSAN BASED VHCL)”.
5.
Touch “ENGINE”.
If “ENGINE” is not indicated, go to
Link Connector (DLC) Circuit/For YD Engine Models"
.
6.
Perform each diagnostic test mode according to each service
procedure.
For further information, see the CONSULT-II Operation Manual.
