Answer
Hi James,
It hints at a problem with the digital data handling by the body computer, but let's try going for a fault code to see if there is something that has been recognized internally by the system.
Turn the ignition switchl:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window of the cluster to see if the mileage reading is replaced by a 4-digit number preceded by a P. If so let me know what it is and we'll go from there. If you don't get a code, then if you have an Autozone parts store nearby they may do a readout from a plug that is under the dash, for free. See if they come up with a fault code.
