Instrument cluster gauges calibration diagnostic

digital part of dash ???? Instrument cluster , gauges etc.... Have the instrument cluster checked for DTC'S - diagnostic trouble code's , yes the instrument cluster an the BCM - body control module (GEM)
Is this what your instrument cluster looks like ?

Principles of Operation
The instrument cluster is a hybrid electronic instrument cluster (HEC). The instrument cluster gauges, warning indicators, and message center displays are either controlled and driven directly through hardwired circuitry, or the information is requested and received through the standard corporate protocol (SCP). The instrument cluster has self-test diagnostics capabilities using the diagnostic tool.

You can try doing a re-calibration of the cluster. To do that.....
Begin the test with the ignition switch in the OFF position. 2. Depress the odometer/trip odometer switch button. 3. While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the ON position, but do not start the engine. 4. Release the odometer/trip odometer switch button. 5. The instrument cluster will simultaneously begin to illuminate all of the operational segments in the VFD units, and perform a bulb check of each operational LED indicator. The VFD segments and LED indicators remain illuminated as each gauge needle is swept to several calibration points and back. If a VFD segment or an LED indicator fails to illuminate, or if a gauge needle fails to sweep through the calibration points and back during this test, the instrument cluster must be replaced. 6. 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.

that is a serious problem on any newer car,
its all electronic and FORT KNOX , tight.
The PCM runs that speedo and odemeter and are now not related
to the insides of the speedo head, like list 100 years. 1900 to now.
POWER TRAIN control MODULE, (old name ECU/ECM)
the PCM stores the miles and then sends them to the Cluster. via the comm bus. (sometimes the BCM is the middle man here)
TIPM (Total Integrated Power Module)
the PCM also knows car speed, at all times, (VSS sensor)
and sends live speed data, full time to the head.
so scan it. Not doing a scan is FAIL time. a NO WIN deal.
take a scan tool and scan it. see what errors you get.???????

Like VSS dead.? or comm bus errors?, or cluster module errors.?
or? or?

that is first.
also on the newer cars 1998+? there is self test in the FSM.
the FSM is a book , (sold at dealers) and is factory service manual
and in said manual there are the self tests. (for sure)
only how , is a question !!!
on mine.
you push buttons and key actions, then the CLUSTER does its a dance. it wags all gauges. etc.
if the speed dont wag the head is bad.

my 08 jeep, I can do this.
on older years, only the dealer scan tool DRB or? can only do that.

RTM , read the FSM or get it serviced.
there are only 2 choices, on cars now.
1 RTM or 2 get help.
You can not fix modern cars without this manual.
nor with out a scan tool. (I use Innova 3160 to cover jeeps)

alldata.com may have these checks.
costs $15 to look.
alldata, is a on line virtual FSM. and is the best one, lacking the real thing.

the below ONLY checks the cluster. !!!

Holding the odometer/trip odometer push button depressed while turning the ignition
switch from the OFF position to the ON position will initiate the CCN self-diagnostic actuator test.

The 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 and the indicators are capable of operating as designed. During the actuator test the instrument cluster
circuitry will position each of the gauge needles at various calibration points, illuminate each of the segments in
the Vacuum-Fluorescent Display (VFD) units, and turn all of the 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 CAN or LIN data bus, the Powertrain Control Module (PCM), the Totally
Integrated Power Module (TIPM), the Controller Antilock Brake (CAB), the All-Wheel Drive Control Module
(AWDCM), the Occupant Restraint Controller (ORC), the compass module, 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.
1. Begin the test with the ignition switch in the OFF position.
2. Depress the odometer/trip odometer switch button.
3. While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the
ON position, but do not start the engine.
4. Release the odometer/trip odometer switch button.
5. The instrument cluster will simultaneously begin to illuminate all of the operational segments in the VFD
units, and perform a bulb check of each operational LED indicator. The VFD segments and LED
indicators remain illuminated as each gauge needle is swept to several calibration points and back. If a
VFD segment or an LED indicator fails to illuminate, or if a gauge needle fails to sweep through the
calibration points and back during this test, the instrument cluster must be replaced.
6. 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. The actuator test will be aborted if the
ignition switch is turned to the OFF position, or if an electronic vehicle speed message indicating that the
vehicle is moving is received over the CAN data bus during the test.
7. Go back to step 1 to repeat the test, if necessary.

There is no module under the dash on your vehicle .
P0463 - Fuel Level Sensor A Circuit High Description: The powertrain control module (PCM) monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves above the maximum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank. Possible Causes:

• Fuel pump (FP) module concern
• Incorrectly installed fuel gauge
• Damaged instrument cluster
• FLI shorted to VPWR
• CASE GND circuit open
• Overfilled fuel tank
• Damaged fuel gauge

Fuel Level Indication System The fuel level indication system is a magnetic gauge system. It consists of a magnetic fuel gauge (9280) mounted in the instrument cluster (10849) and a sending unit located in the fuel tank (9002) with an instrument cluster gauge amplifier (10E849) in series between the two. No instrument voltage regulator is used with this system. Fuel Gauge
The magnetic gauge movement consists of three primary coils, one of which is wound at a 90-degree angle to the other two. The coils form a magnetic field which varies in direction according to the variable resistance of the sender unit which is connected between two of them. A primary magnet, to which a shaft and pointer are attached, rotates to align to this primary field, resulting in pointer position. The bobbin/coil assembly is pressed into a metal housing which has two holes for dial mounting. There is no adjustment, calibration or maintenance required for these gauges. The instrument cluster amplifier is calibrated to the fuel gauge. The instrument cluster amplifier and fuel gauge must be replaced as a system. Instrument Cluster Gauge Amplifier/Check Gauge Module
The instrument cluster gauge amplifier electrically averages fuel sender readings so the fuel gauge displays actual fuel level and not fluctuations due to sloshing in fuel tank. The instrument cluster gauge amplifier is a small printed circuit board which latches into a pocket on the back of the instrument cluster. The electrical connections for ignition, ground, input from fuel sender and output to fuel gauge are made through a spring-type connector on the instrument cluster gauge amplifier to the instrument cluster printed circuit (10K843) on the instrument cluster. There are no provisions for calibration or adjustment of the instrument cluster gauge amplifier.
Fuel Sending Unit
The fuel sending unit consists of a variable screened resistor made up of a ceramic substrate. It is controlled by the action of an attached float in the fuel tank. When the fuel level is low, resistance in the sending unit is low. When the fuel level is high, the resistance in the sending unit is high. As the float moves from empty to full, the resistance will gradually and continuously increase.

I hope that you can solve your problem.

Good luck!!!
