MULTI-MODE MANUAL TRANSAXLE SYSTEM ADJUSTMENT

1. USING INTELLIGENT TESTER: CLAMP POSITIONADJUSTMENT (CLUTCH POSITIONADJUSTMENT)

Tech Tips

The multi-mode manual transmission system has a load controlled clutch cover (adjustment system). The pressure plate moves depending on the wear

condition of the clutch disc lining.

When removing or installing any parts related to the multi-mode manual transmission system, move the clutch actuator to the clutch clamp position. This is

for normal operation of the load controlled clutch cover (adjustment system).

If the clutch position adjustment operation input fails, perform the operation again from step (a) more than 15 seconds after turning the ignition switch off.
