Toyota Corolla Cross: Check For Intermittent Problems
Toyota Corolla Cross (2022-2025) Service Manual / Engine & Hybrid System / M20a-fxs (engine Control) / Sfi System / Check For Intermittent Problems
CHECK FOR INTERMITTENT PROBLEMS
HINT:
Inspect the vehicle 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.
- Clear the DTCs.
- Change the ECM from normal mode to check mode using the GTS.
