CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Shift Paddle Switch Circuit
| DTC Code | DTC Name |
|---|---|
| Shift Paddle Switch Circuit |
DESCRIPTION
When the shift lever is in M, the shift range can be changed using the shift paddle switches. It is also possible to select the shift range when the vehicle is being driven with the shift lever in D by operating the shift paddle switches.

CAUTION / NOTICE / HINT
Perform initialization when parts related to the continuously variable transaxle are replaced.
Check that no DTCs are stored after performing initialization.
