02 400 hp ISL warning light question help

[Skip426]

Don, I don't know if you've come up with an answer yet, but the warning light your wondering about may be related to another system on the chassis ( Freightliner/ Spartan ) and not the engine, and you may get more replies posting it in the chassis forums than here. Like you, I have only the one light that stays on long enough to see what the symbol is, after the bulb check flash. Could you post a picture ?
Good luck .

If all manufacturers are following the same standard, then the amber warning light with the circled exclamation mark indicates that you have an exterior light out. See the following link.

What does the amber circle dashboard warning light with the exclamation point mean on a 1999 Ford Windstar van

[Gary RVRoamer]

Freightliner uses two different icons that would be described as a circle with an exclamation point. One has two line on either side outside the circle, sort of like parenthesis - that one means low air. In another one, the circle has ridges, like a geat tooth. That one means to check the transmission. I didn't think these were used on a 2002, though. My 2004 doesn't have either one - my warning displays are mostly brief words highlighted in yellow or red, e.g. Check Engine or Checks Trans.

The meaning of the dash lights is established by the chassis builder, not Cummins, so this question would be more appropriate to one of the chassis forums, i.e. Spartan or Freightliner (whichever you have).
