Free ASE webinar: OBDII – reading between the lines (Pt. 2)

by | Feb 5, 2024 | 0 comments

The National Institute for Automotive Service Excellence (ASE) is hosting a free webinar for service technicians on Tuesday, Feb. 6 at 4:00 p.m. ET entitled “OBDII Data – Reading Between the Lines (Part 2).”

Technical trainer Rick Escalambre returns for part two of his presentation on OBDII data with a special emphasis on coping with incomplete monitor tests.

There is valuable data to be collected from the scan tool while sitting in the driver’s seat. Every diagnostic trouble code (DTC) that turns on the malfunction indicator light (MIL) has a related monitor test.

A MIL commanded “On” means a monitor test ran and failed. Whether or not the technician is part of an emissions program, the commanded “O” MIL means an emissions failure has occurred. 

This webinar will fill in “between the lines” what the books do not tell the technician. The systematic approach presented will demonstrate the difference between a readiness flag and individual monitor tests, explain the differences between monitoring test completions and conditions, and how to use MODE $09 (in-use performance monitor tracking) and MODE $06 (test results) to identify possibly difficult-to-run monitor tests.

Those who missed Part 1 of this two-part presentation can register to view the recorded version of Part 1 here.
