That looks like a good collection of test subjects!
Maybe its something like.. a couple bytes in the first line increase/decrease which causes the odo to "decrease" by 1.
And the other bytes decrease which causes the odo to increase by 2 each time?
Hopefully that kinda makes sense?
Would have to go through the top line decrease each byte by 1 to see what happens. Alternatively, get the scantool on there, change the odo and then read out whats changed... since we will expect to see the DTC set byte to change when the odo is set by a scantool.
Also.. the byte that turns the police mode on, what happens if we set that to FF? Id assume that byte will have multiple "options" that can be turned on so FF will enable everything.
Sorry LangasLS, it seems your the only one with a cluster to tinker with! Im currently overseas so no playing till the newyear!
