CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM(for 8NR-FTS) CHECK FOR INTERMITTENT PROBLEMS

Tech Tips

Troubleshoot malfunctions with the ECM in 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.
