Thanks for the speedy response. I will test this tomorrow and I will get back to you. I don't I am not aware that I have a trip odometer. But that doesn't mean I don't have one. I will let you know tomorrow evening.


I thank you for responding to my question. You added additional information to the response from Cameron.

If your doing this to check what lights may or may not be on, just get a simple image on google and compare. If you want to do other tests, a quick search brought this up and this might be what your looking for.

Hope this helps! If it answered your question, please hit the answer button!

I really am impressed with the speed of the reply. Thank you very very much. It is exactly what I was looking for. I have 3 issues and all point to the Instrument Cluster or the Body Security Module. So I asked about the Cluster Self Test first. I have already checked the fuses that were suggested as possible culprits. I will ask questions about the issues separately. Thank you Cameron for your help.

I found this information on HOW TO RUN INSTRUMENT PANEL ONBOARD DIAGNOSTIC TEST. Unfortunately, I cant find the code results chart (defining err results). guess I have to call the dealership. Hope this helps..

1.With the key in the ignition and in the off position press and hold the odometer / trip button.

2.Turn the truck to ‘On’ but do not start the truck.

3.After a few seconds the gauges will sweep from nothing to max, release the odometer / trip button.

4.The odometer should now read ‘GUAGE’, you are now in a information mode.

5.Start the truck

6.Now every time you press the odometer / trip button it will cycle through the information available.

7.When you shut the truck off the odometer will go back to showing mileage.

GAGE - Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM.

All segments illuminated.

Illuminates all odometer segments.


Illuminates all micro-controlled lamps and LEDs.

r ####

Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline).
