2003 Dually H.O. 6 speed with 40,000 miles. Really just started working it hard. Wife pulling about 13000lbs. She says intermittently the CNHECJK GAUGES light comes on just long enough to get your attention and goes off. She says she sees no issues on gauges when this occurs. Hey this forum use to be broken down in groups. What happened or did I miss something?

 

The dealer can fix that for you, it isn't anything but an annoyance.


You missed something.

 

I found the TSB for a gauge reflash.

 

ive noticed over the years this happens to me when my batts need to be replaced from the huge draw the grid heaters put on them.

 

This is while cruising 70 mph and on the road from a hour plus. The TSB addresses this. TSB 08-004-03 I will say my truck has the ORIGNAL batterys! There is no lag in starting at all. It still turns over and fires up like it was new.

 

My truck does the same thing.
