Toyota Tacoma (2015-2018) Service Manual: Check For Intermittent Problems
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.
- Clear DTCs (See page

). - Switch the ECM from normal mode to check mode using the Techstream (See
page ).
- Perform a simulation test (See page
).
- Check and wiggle the harness(es), connector(s) and terminal(s) (See
page ).
