For example
(I was lazy to take my own pics, so this out from the net:)

So, this is how you read it:

    Test 7.0 = Coolant Temp

    097       = 97 degrees

This helps when you want to monitor certain vitals. For example, for my battery going flat something after a few cranks:

1) unlock your cluster

2) look at Test 9.0 for the volt reading (before car running)

3) start the car

4) continue to monitor Test 9.0 for the volt reading (car running)

If the reading is lower than normal for 2), battery probably needs replacing.

If the reading is lower than normal for 4), alternator probably having problem.
