AUTOMATIC TRANSAXLE SYSTEM Pattern Select Switch Sport Mode Circuit

DTC Code DTC Name
Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The TCM memory contains the programs for the normal and sport shift patterns.

By following the programs corresponding to the signals from the combination switch assembly, park/neutral position switch and other various sensors, the TCM switches the shift solenoid valves on and off, and controls the transaxle gear ratio.

CAUTION / NOTICE / HINT

Tip:

  • Refer to the inspection procedure for the CAN communication system.

  • If the CAN communication malfunctions, the TCM cannot receive current data from the ECM. In this case, the freeze frame data output from the TCM has not been updated, so the data will not be useful for the inspection. However, reading the Data List as the first step in troubleshooting is an effective way to find malfunctions.

  • The malfunctioning area can be confirmed using the Bus Check function of the GTS.
