Toyota CH-R Service Manual: Check For Intermittent Problems

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.
