(7) Push the TCS OFF switch to ON. (With TCS mod-
els)
(8) Designate mode using function key.
Function mode: F12
(9) Move selector lever to“D”and slowly increase
vehicle speed to 75 km/h (47 MPH).
(10) Read data on Subaru select monitor.
SPECIFIED DATA:
95% (Wheel locked-up)
5% (Released)
NOTE:
The speed difference between front and rear wheels may
light either the ABS or the ABS/TCS warning light, but this
indicates no malfunctions. When AT control diagnosis is
finished, perform the ABS or the ABS/TCS memory clear-
ance procedure of self-diagnosis system.
