Question about 2000 Honda VFR 800
My LCD display has faded out and it is very difficult to view the engine temperature, odometer reading and also trip meter
Thats unfortunate, because you will have to buy a new gauge cluster, and those arnt cheap.

You can retrieve/display DTC's (trouble codes) by a method referred to as the odometer self-diagnostics which can display and delete speedometer, tachometer, TSM, TSSM or HFSM, ECM and ABS (if equipped) codes but not radio codes which are accessed through the radio itself and are shown on its own display.
In order to display odometer DTC's press and hold the trip odometer reset switch while you are turning the ignition switch to "ON", then release the trip odometer reset switch at which time "diag" will appear on the LCD display where normally the odometer reading would be. When "diag" appears you are in the diagnostic mode so if you next press and release the trip odometer reset switch again "PSSPtb" appear where diag previously was seen. This tells you what different modules are on the motorcycle that are set up or able to display DTC's. "P" indicates ECM codes; "S" indicates TSM, TSSM or HFSM codes; "SP" indicates Speedometer codes; "t" indicates tachometer codes; and "b" indicates ABS codes. "no rsp" will be displayed if the engine stop switch is not in the RUN position so be sure that you have the engine stop switch in the RUN position. Also if the motorcycle does not have a certain module "no rsp" will be displayed to indicate the absence of that certain/specific module. If the motorcycle does have the module you want to check for codes on then you can go through the modules until you get to the one you want to check for codes. To move through the code categories quickly press and release the trip odometer reset switch and each of the letters will appear and flash as each mode is selected, When the letter that corresponds to the module you want to check codes for appears hold the odometer reset button in and if there are no DTC's set for that module the word "none" will appear. If any current or historical DTC's are stored in the module, they will appear on the odometer. And if you quickly press and release the trip odometer reset switch the display will alternatively display the DTC numbers one at a time until they have all been displayed. When you have gone through all of the code categories "end" will be displayed. If you want to clear out or delete all codes in that module press and hold the odometer reset switch. If you do not want to remove or delete the recorded DTC's then quickly press and release the trip odometer reset switch at which time the module part number will be displayed and if you press and release the odometer reset switch again the next module's information will be displayed. When you are done and wish to exit the diagnostic mode just turn the ignition switch to "OFF".

through the stored DTCs.
The ECM will show "no rsp" if the engine stop switch is not in
the RUN position. Verify the engine stop switch is in the RUN
9. If odometer displays "no rsp" then the motorcycle may not
be equipped with the module. If the motorcycle is equipped
with the selected module then go to other modules and
look for applicable communication codes.

Here is some 2001 information that may be helpful
The 2001 DYNA electronic speedometer consists of a speed sensor, an odometer reset switch and the speedometer itself. The speed sensor is located on the right side of transmission case below the starter. It is a Hall Effect sensor that is triggered by the gear teeth of 4th gear on the transmission mainshaft. The output from the sensor is a series of pulses that are interpreted by speedometer circuitry to control the position of the speedometer needle and the liquid crystal (LCD) odometer display. The odometer mileage is permanently stored and will not be lost when electrical power is turned off or disconnected. The odometer reset switch allows switching between the odometer and the trip odometer displays. To zero the trip odometer, while having the odometer display visible, press and keep the function switch depressed. The trip odometer mileage will be displayed for 2-3 seconds and then the trip mileage will return to zero miles. The odometer can display six numbers to indicate a maximum of 999999 miles. The trip odometer can display six numbers with a tenth of a mile accuracy for a maximum of 99999.9 miles. Circuitry in the speedometer also uses the sensor input to provide an input to the turn signal canceller. This turn signal canceller input was previously supplied by the reed switch in mechanical speedometers.
To enable diagnostic mode depress the odometer reset switch and turn ignition/key switch to ON, to clear codes turn the ignition switch from OFF to ON while holding the reset switch in. Press and release the reset switch to cycle through the codes. Set codes will display as Code d0xSet. Holding the reset switch in will result in Code d0xClr being displayed indicating that the code has been cleared. To return the speedometer to the normal operating state cycle the ignition/key switch.
Remove the seat for testing. Remove the speed sensor and check for accumulation of debris on it and if there is any debris present, clean it away and if there is not debris replace the sensor.
Disconnecting the speed sensor will cause code d02 to set.
ODOMETER, TRIP ODOMETER AND RESET SWITCH TESTING
Turn the ignition ON. Does odometer display consist of the correct numbers?
If YES Press trip reset switch. Does the LCD display toggle between trip and odometer modes? BUT if the odometer display does not consist of the correct numbers replace the speedometer.
If the speedometer does display the correct numbers press the trip reset switch. Does the LCD display toggle between the trip and odometer modes? If No Loosen the trip reset switch boot and then tighten it again until it is snug and toggle the switch again and verify if it toggles between trip and odometer modes? If YES does the trip display consist of correct numbers? If it does STOP here and go to test 2A If No replace the speedometer.
If loosening and retightening the reset switch boot results in okay toggling between the trip and odometer modes the Speedometer is OKAY. If it does not, then remove the rubber boot from the reset switch and toggle it without the rubber cover and if it now toggles between the trip and the odometer modes replace the reset switch boot/cover. If it does not now toggle between the trip and odometer modes place a jumper wire across the leads to the reset switch on speedometer connector. Does the LCD display now toggle between the trip and the odometer modes? If yes replace the reset switch and if No replace the speedometer.
Speedometer Test 2A
SPEEDOMETER INOPERATIVE, READS HIGH/LOW, NEEDLE STICKS, INTERMITTENT/ERRATIC, OUTPUT SPEED SIGNAL INOPERATIVE
Turn ignition ON. Is speedometer backlighting on? If NO then If speedometer backlighting is not on, check for 9-12 VDC on the O/W wire at connector
[39B]. If the proper voltage is present check for continuity to ground on the BK wire at connector [39B]. If there was not appropriate voltage on the )/W wire at connector [39B] locate and repair an open in the O/W wire.
If there is continuity at the BK wire at connector [39B] replace the speedometer. If there is not locate and repair an open in the BK wire.
If there is backlighting enable diagnostic mode and clear codes. Then recheck for codes. If there are any codes present go to the applicable
code in Speedometer Test 2B (d0x).
If there are no codes set return the speedometer to its normal state, raise the rear wheel from the ground, put the transmission in 5th gear, turn the ignition ON, spin the back tire, enable diagnostic mode and check for codes and if there are any codes set now make repairs to the harness/connections.
