Title: A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/ Canister Pump Module): CHECK FOR INTERMITTENT PROBLEMS; 2019 - 2020 MY RAV4 HV [02/2019 - 08/2020]

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.

  1. Clear the DTCs.
