Thanks for the help!

If you have the 233 transfer case (3 push button switch on the dash), you can jump pin #13 to pin #4(ground). Turn the key to on and watch the lights on the switch. If they only come on for a second and do not come back on, there are no codes stored. If there are codes stored in the TCCM, the lights will flash together. If they flash once, then you have a #1 trouble code, twice is the #2 trouble code, etc..

As long as the pins are jumped together the code will continue to flash in 5 or 10 second intervals.

Count the pins from left to right starting at the top to get the pin #. For example, pin #1 will be at the top left.
