Subaru Crosstrek Service Manual: Drive cycle Procedure
CONTINUOUSLY VARIABLE TRANSMISSION (DIAGNOSTICS) > Drive Cycle
PROCEDURE
It is possible to complete diagnosis of the DTC by performing the indicated drive cycle. After the repair for the DTC, perform a necessary drive cycle and make sure the function recovers and the DTC is recorded.
1. PREPARATION FOR DRIVE CYCLE
1. Check that the battery voltage is 12 V or more and fuel remains approx. half [20 — 40 L (5.3 — 10.6 US gal, 4.4 — 8.8 Imp gal)].
2. After performing the diagnostics and Clear Memory Mode, check that no DTC remains. Clear Memory Mode">
NOTE:
Perform the drive cycle after warming up the engine except when the ATF temperature at engine start is specified.
