Toyota RAV4 Service Manual: Check for intermittent problems

Toyota RAV4 Service Manual / 2Az-fe engine mechanical / Sfi system / 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 (see page es-35).
  2. Switch the ecm from normal mode to check mode using the intelligent tester (see page es-38).
  3. Perform a simulation test.
  4. Check and wiggle the harness(es), connector(s) and terminal(s).
