| Title: 2GR-FE (ENGINE CONTROL): SFI SYSTEM: CHECK FOR INTERMITTENT PROBLEMS; 2016 MY Sienna [12/2015 - 08/2016] | ||
CHECK FOR INTERMITTENT PROBLEMS
HINT:
Inspect the 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.
