QuestionQUESTION: Yesterday, our electrical system was acting screwy and all of the gauge needles were jumping all over the place. I finally disconnected the main fuse, and the speedometer and tachometer gauge needles are stuck pinned at the maximum position (the opposite side of the pole from 0 mph/0 rpm).
Would anyone know how to get those needles back to 0? I would've thought there is a fuse for those, but I didn't see anything clearly listed in the manual.
Thank you for any help.

QUESTION: 2005 Liberty
AnswerThe instrument cluster actuator test will put the instrument cluster into its self-diagnostic mode. In this mode the instrument cluster can perform a self-diagnostic test that will confirm that the instrument cluster circuitry, the gauges, the PCI data bus message-controlled indicators, and the chime tone transducer are capable of operating as designed. During the actuator test the instrument cluster circuitry will sound the audible tone transducer, position each of the gauge needles at various calibration points, illuminate each of the segments in the Vacuum-Fluorescent Display (VFD) unit, and turn all of the PCI data bus message-controlled indicators ON and OFF again.
Successful completion of the actuator test will confirm that the instrument cluster is operational. However, there may still be a problem with the PCI data bus, the Powertrain Control Module (PCM), the Airbag Control Module (ACM), the Body Control Module (BCM), the Electronic Vehicle Information Center (EVIC), the Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM), or the inputs to one of these electronic control modules. Use a diagnostic scan tool to diagnose these components. Refer to the appropriate diagnostic information.
Begin the test with the ignition switch in the OFF position.
Depress the odometer/trip odometer switch button.
While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the ON position, but do not start the engine.
Release the odometer/trip odometer switch button.
The instrument cluster will automatically begin the actuator test sequence, as follows:
The cluster will turn ON, then OFF again each of the PCI data bus message-controlled indicators to confirm the functionality of the indicator and the cluster control circuitry:
The cluster will sweep the needles for each of the gauges to several calibration points in sequence to confirm the functionality of the gauge and the cluster control circuitry:
The cluster will sequentially step the odometer/trip odometer VFD unit display from all ones (111111) through all nines (999999) to confirm the functionality of all VFD unit segments and their control circuitry, then display the software version number.
The cluster will generate five (5) chime tones to confirm the functionality of the audible tone transducer and the control circuitry.
The actuator test is now completed. The instrument cluster will automatically exit the self-diagnostic mode and return to normal operation at the completion of the test, if the ignition switch is turned to the OFF position during the test, or if an electronic engine speed message indicating that the engine is running is received from the PCM over the PCI data bus during the test.
Go back to Step 1 to repeat the test, if required
