Sfi System -- Check For Intermittent Problems


HINT:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with the Techstream 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 DTCs (COROLLA_ZRE142 RM000000PDK0ZAX.html).
  2. Switch the ECM from normal mode to check mode using the Techstream (COROLLA_ZRE142 RM000000PDL0PIX.html).
  3. Perform a simulation test (COROLLA_ZRE142 RM000000UZ108OX.html).
  4. Check and wiggle the harness(es), connector(s) and terminal(s) (COROLLA_ZRE142 RM000000UZ30C8X.html).
