Digital Cluster IN-CAR self diagnostics

I found this information somewhere years ago, it is copy and paste and I do not know who the author is, but credit given to them.

On older Chrysler electronic instrument display clusters that have a tachometer, the self-diagnostic sequence is initiated by pressing the TRIP and TRIP RESET buttons simultaneously, turning the ignition on, then releasing the buttons. On those without a tach, press STEP and U.S./MET buttons simultaneously. If nothing happens, the cluster is bad. The odometer should display EIC indicating the cluster is ready to begin the self tests.

To begin the first 5 tests, press the U.S./MET button. All vacuum fluorescent displays should illuminate. If the number 1, 2 or 3 displayed on the speedometer, there is a fault in the speedometer and the cluster needs to be replaced. A fault code 4 indicates a problem in the odometer memory chip (only the chip has to be replaced). When the number 5 appears, the cluster has passed the first five tests.

To sequence through the next 3 tests, you have to press the U.S./MET button each time. The sixth test illuminates all the individual display segments and flashes a 6 when complete. Test 7 lights up all the gauge scales and symbols and flashes a 7 when complete. Test 8 lights up the warning lamps in sequence and flashes an 8 when through. If the cluster passes all 8 tests, then the problem is outside the cluster.

If you have a Chrysler dash where the fuel, temp and oil gauges all read maximum and remain there after the engine has started, check for a loose module connector on the back of the cluster.

If the speedometer and odometer do not work, check the operation of the "distance sensor" (speedometer sending unit) on the transaxle with an ohm meter. Set the scale so that readings of less than one ohm will be shown clearly. Connect the meter to the sensor terminals and turn it. A good sensor should produce eight distinct pulses of 0.5 ohms or less with every revolution. Do not use a test light on the sensor as doing so may damage it.
