2.0L EJ20X 4cyl 16v DOHC Turbo MPFI Petrol
This 2003 Subaru Liberty (BL) (2.0L EJ20X 4cyl 16v DOHC Turbo MPFI Petrol) page collates 2 diagnostic files and 2 scan or scope images submitted by qualified automotive technicians across 2 data categories. Every file in the set was captured from a vehicle that was running correctly at the time of recording, giving technicians a known good baseline to compare against when diagnosing a faulty 2003 Liberty (BL) in their own workshop.
Typical uses for a data set like this include verifying live-data PID values and freeze-frame snapshots, confirming oscilloscope waveform shape and timing for primary and secondary ignition, checking CAN bus activity on modules that are suspect, and ruling out good-component scan tool readings when chasing an intermittent fault on the same chassis. Every file is attributed to the submitting member and reviewed before it appears on the site.
This vehicle has known good data covering 2 distinct scan and scope capture categories, organised by the vehicle system they relate to. Each item below represents a data file or waveform set recorded from this specific year/make/model combination with the engine and vehicle in a confirmed healthy state.
The 4 submitted files cover the following formats, captured on a mix of scan tools and lab-scope hardware used by TaT members in professional workshops:
Each thumbnail below corresponds to a submitted image in this data set. Images are blurred for public viewing; members see the full-resolution capture with measurement cursors, channel labels and the scan tool's on-screen legend intact.
