Check For Intermittent Problems


CHECK FOR INTERMITTENT PROBLEMS

LEXUS HAND-HELD TESTER only:
By putting the vehicle's ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTCs.
(2) Set the check mode.
(3) Perform a simulation test.
(4) Check the connector and terminal.
(5) Handle the connector.
