Part 1

FA20 ENGINE CONTROL: SFI SYSTEM: DATA LIST / ACTIVE TEST; 2013 MY FR-S [03/2012 -]

1. DATA LIST

HINT
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

NOTICE:
* In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
* The actual values may differ from the values listed in the chart under "Results of real-vehicle check" due to climate, weather conditions, etc.

HINT
