Cruise control system is controlled by ECM. Each switch and circuit can be checked by taking measurement of
terminal voltage and terminal to terminal resistance of ECM. When measuring these values, be sure to read
precautions for measurement described under “Inspection of ECM and Its Circuits in Section 1A”.
