Problem w/ High Lock?

[PARAGON]

Why does the title of the thread say HI lock if you are backing out of your driveway and coming home from work?

Paragon,
You are correct.. The title of the thread is incorrect. It should say "Problem with 4 High" or "Problem w/ 4 High light indicator"

This was 3rd time I've seen this. The light indicator was on "N" instead of normal 4 High. So, I press the 4 High button and it blinks for a few seconds and goes into 4 High. I don't remember not having any power.

The transfer case shift control module flashes each indicator lamp after a shift has been requested and continues to flash until the transfer case shift control module can complete the shift. If the transfer case is unable to make a shift, the requested mode indicator flashes and returns to the previous mode. If the requested mode indicator flashes for 15 seconds and returns to the previous mode, this indicates the loss of a necessary input from another module. The transfer case shift control module requires a vehicle speed sensor signal (VSS), provided by the ABS module, and a PRNDL input provided by the transmission. These signals are provided to the transfer case shift control module via class 2, and if not received the transfer case will not shift.

Also, a bad ground or connection in the tcase switch can cause the light to light-up.

Check to see if it shifts in and out of 4HI lock, 4LO, Neutral and 4HI without hiccups.
