Sfi System -- Check For Intermittent Problems


HINT:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with an 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 an intelligent tester (RAV4_ACA30 RM000000PDL09GX.html).
  3. Perform a simulation test (RAV4_ACA30 RM00000135201PX.html).
  4. Check and wiggle the harness(es), connector(s) and terminal(s) (RAV4_ACA30 RM000000UZ306OX.html).
