NOTE
11.GENERAL SCAN TOOL
Using general scan tools will greatly improve the ef-
ficiency of repairing engine electronic controls.
Subaru Select Monitor can be used to diagnose the
engine, ABS, air conditioner and other parts.
12.AWD CIRCUIT MEASURES
1) Full-time AWD MT model
Since viscous coupling (limited slip differential) is
used in the center differential, cut-off of AWD circuit
cannot be carried out.
2) Full-time AWD 5AT model
Since VTD type is used in the center differential,
cut-off of AWD circuit cannot be carried out.
3) Full-time AWD 4AT model
Insert a spare fuse into FWD fuse holder in the fuse
box located in the left side of engine room to select
the FWD. Since electronically controlled MT-P hy-
draulic multi-plate clutch is adapted for center dif-
ferential, select FWD. When maintenance is
performed with jack-up or on the free roller, check
the illumination of AWD warning light in the combi-
nation meter.
