Setting up IDS to record when certain conditions occur is
another way to let the scan tool work for you. Today, I had
an 03 Explorer with the O/D light flasing and P0741 in
memory. I cleared the DTC and wanted to take a 2 minute
recording (1 min pre/1 min post) when the PCM set a DTC.
First, you select the PIDs you want to view, and in this
case, I also needed the DTC status PID because that would be
the PID triggering my recording. Once Datalogger is up,
highlight the DTCCNT PID (or the PID you want to trigger off
of) and go into this screen (hit the button under "#"):
Trigger setup: [IDS Triggering]
When you hit the "Autocapture" button, the options on the
right of the screen will be displayed. If you select "Beep",
IDS will activate a tone telling you a recording has been
triggered. Hitting the "i" buttion will explain the
difference between "Transition" & "Condition".
Since I had just cleared the DTCs, P1000 was in memory and
the DTCCNT PID was recognizing that; so I had to set my
upper limit to 1. If, while driving, the P1000 clears, you
need to set the upper limit to 0.
Here's my recording time setup:
[IDS Triggering]
Unfortunately, the P0741 didn't return during the test drive
so I had to induce a DTC for this example. This is what I
got:
[IDS Triggering]
You can use any PID to trigger a recording and there are
tons of different cases where this can be useful. Here's
another example where I triggered a recording:
[2006 Ford F-250 Super Duty XL, ECM/Inputs/Outputs Scan
Data]
In that case, nobody was around to watch the screen or
wiggle the harness and I didn't feel like routing all that
IDS cabling to the engine bay. I knew something happened
when I heard the "Beep".
Maybe this will help someone.
