Title: 2UZ-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: CHECK FOR INTERMITTENT PROBLEMS; 2007 MY LX470 [08/2006 -        ]

CHECK FOR INTERMITTENT PROBLEMS

HINT:

Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with the intelligent tester 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.

  1. Clear the DTCs.
  2. Switch the ECM from normal mode to check mode using the intelligent tester.
  3. Perform a simulation test.
  4. Check and wiggle the harness(es), connector(s) and terminal(s).
