So I own two 06 cummins, my wife’s truck is the only one that does this so far.
When it’s cold outside in the mornings the truck starts just fine, but when it’s driving at 65, 70 the grid heater light comes on and chimes. I’ve read a couple forums and they all revert back to a smarty tune however her truck does NOT have a smarty tuner. When we bought the truck it had a bully dog gt tuner that I swiftly took off and (since I work at a dodge dealership) reflashed the pcm back to its stock configuration.
When the light kicks on, it does chime a few times but if I drop speed below 60 the light turns off and only turns on again when I hit 65+.
Anyone have any ideas?
