SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURENLAT0281S04After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-IINLAT0281S04011) Start engine.
2) Select ªSELF-DIAG RESULTSº mode for CVT with CONSULT-
II.
3) Drive vehicle under the following conditions:
Selector lever in ªDº position, vehicle speed higher than 10
km/h (6 MPH), throttle opening greater than 1/8 of the full open
position, engine speed higher than 450 rpm and driving for
more than 10 minutes.
Without CONSULT-IINLAT0281S04021) Start engine.
2) Drive vehicle under the following conditions:
Selector lever in ªDº position, vehicle speed higher than 10
km/h (6 MPH), throttle opening greater than 1/8 of the full open
position, engine speed higher than 450 rpm and driving for
more than 10 minutes.
