Instrument Panel Cluster

For this portion of the presentation we are
going to turn our attention to testing portions
of the instrument cluster.

There are times where you will need to test
certain items in the instrument cluster, such as
the fuel gauge, to see if they are responding to
the commands sent from the fuel level sending
unit.

To do this we need to enter the “Instrument
Panel” option of the body and accessories
function menu on the Tech 2.

After we have followed the prompts on the
screen, the Instrument Panel Cluster function
appears with the options Display Test,
segment Check, and Dimming Intensity.

We have selected the Display Test option and
you can see that a screen appears with an On
and Off tab at the bottom.

Clicking the On tab will tell the tool to sweep
all of the gauges in the cluster from the high to
low position. If any of the gauges fails to
respond to this command, you can be fairly
sure that there is a problem with the gauge
itself.

If you had an inaccurate fuel gauge, the next
step would be to test the fuel level sender and make sure that it was reporting to the responsible
module.
