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 ).

Pressure Control Solenoid "B" Performance (Shift Solenoid Valve SL2) (P0776)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
