6CHECK INPUT SIGNAL FOR TCM USING
SUBARU SELECT MONITOR.
1) Connect all the connectors.
2) Lift-up the vehicle and support with rigid
racks.
NOTE:
Raise all wheels off floor.
3) Start the engine, and drive it.
4) Read the current data of front wheel speed
using Subaru Select Monitor. 5AT(diag)-15, READ CURRENT DATA, OPER-
AT I O N , S u b a r u S e l e c t M o n i t o r . >
NOTE:
The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When AT control di-
agnosis is finished, perform the VDC memory
clearance procedure of on-board diagnostics
system. ORY MODE, OPERATION, Subaru Select
Monitor.>
