tery voltage is between 11.0V and 16V at idle.

with CONSULT-II.

consecutive minutes.

EC-185.
WITH GST
NFEC0837S02
1) Start engine.
2) Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2
consecutive minutes.

be performed twice as much as when using CONSULT-II
because GST cannot display MODE 7 (1st trip DTC) con-
cerning this diagnosis. Therefore, using CONSULT-II is
recommended.
