Title: M20A-FKS (ENGINE CONTROL): SFI SYSTEM: CHECK FOR INTERMITTENT PROBLEMS; 2019 - 2025 MY Corolla Corolla Hatchback [06/2018 - ] |
CHECK FOR INTERMITTENT PROBLEMS
HINT:
Inspect the vehicle ECM using check mode. Intermittent problems are easier to detect with the Techstream 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.
