CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM CHECK FOR INTERMITTENT PROBLEMS

Tech Tips

Inspect the ECM using check mode. Intermittent problems are easier to detect with the GTS when the ECM is in check mode. In check mode, the ECM uses 1-trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2-trip detection logic.
