CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Pattern Select Switch Sport Mode Circuit
| DTC Code | DTC Name |
|---|---|
| Pattern Select Switch Sport Mode Circuit |
DESCRIPTION
The ECM memory contains programs for normal and sport shift patterns.
By following the programs corresponding to the signals from the combination switch assembly, the park/neutral position switch and other various sensors, the ECM switches the shift control solenoid valves on and off, and controls the transaxle gear ratio.
