Toyota Corolla Cross: Check For Intermittent Problems



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.

  1. Clear the DTCs.
  2. Change the ECM from normal mode to check mode using the GTS.
