Cluster not showing rev;s,speed,fuel and temperature

Odometer The instrument cluster receives odometer rolling count status from the PCM-engine computer and stores the mileage in non-volatile memory (NVM). When the instrument cluster fails to receive the odometer rolling count status for more than two seconds, the odometer display will show dashes.

HEC Dealer Test Mode
To enter the HEC Dealer Test Mode, depress and hold the instrument cluster SELECT/RESET button and then turn the ignition switch to the RUN position. Continue pressing the SELECT/RESET button (5 seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within 3 seconds of the odometer displaying tESt to begin the dealer test mode. Depress the SELECT/RESET button to advance through the following steps until dtc is displayed. Depressing the SELECT/RESET button will display any continuous DTCs stored before proceeding to the next step.

All segments illuminated Illuminates all odometer segments. If any odometer segment is inoperative, INSTALL a new instrument cluster; REFER to Instrument Cluster .
Odometer Display Description GAGE Activates gauge sweep of all gauges, then displays present gauge values. Also carries out the checksum tests on ROM and EE. If the gauge sweep is inoperative, INSTALL a new instrument cluster; REFER to Instrument Cluster . All segments illuminated Illuminates all odometer segments. If any odometer segment is inoperative, INSTALL a new instrument cluster; REFER to Instrument Cluster . bulb Illuminates all micro-controlled lamps and LEDs (low oil pressure/high coolant temperature, low fuel, service engine soon, brake, low range). INSTALL a new bulb or LED as necessary. r Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline). If alternating flashes of FAIL and ROM level are displayed, INSTALL a new instrument cluster; refer to Instrument Cluster . EE Displays hexadecimal value for EE level (used when requesting assistance from the hotline). If alternating flashes of FAIL and EE level are displayed, INSTALL a new instrument cluster; refer to Instrument Cluster . dt Displays hexadecimal coding of final manufacturing test date (used when requesting assistance from the hotline). dtc Displays continuous DTCs. Pressing the SELECT/RESET button will display any DTCs stored before proceeding to the next step. enG Displays the English speed in mph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. m Displays the English speed data (mph) received from the PCM via SCP Network. Displays the metric speed in kph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. tAc Displays the tachometer data received from the PCM via the SCP Network. Tachometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if engine rpm is 0. FUEL Displays the actual A/D fuel level. The fuel gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically. If the value displayed is between 0 and 20, the circuit is shorted. GO to Pinpoint Test D .

• 255=open send +/-0
• 232=Full stop +/-10
• 215=Full mark +/-10
• 178=3/4 mark +/-8
• 138=1/2 mark +/-7
• 93=1/4 mark +/-5
• 41=E mark +/-4
• 54="LOW FUEL" (0-59)
• 0-18=short (0-20 max.)

OIL Displays the code (0-255) for the oil pressure switch input to the HEC. Displays the oil pressure reading input to the HEC. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6 psi) will display a value between 000 and 176. A low oil pressure (less than 6 psi) or an inoperative engine oil pressure switch will display a value greater than 176. dEGC Display of engine temperature in Degrees C input from cylinder head temperature sensor. If the value displayed is -40C, the SCP message for engine temperature has not been received for more than 5 seconds. GO to Pinpoint Test E .

• 49 C="C" mark.
• 60 C=Normal band start.
• 120 C=Normal band end.
• 119 C=Temperature warning indicator ON.
• "-40" C=No SCP Message for 5 sec.

br Displays the brake fluid level input to the HEC. bAtt Displays the code (0-255) battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.

• 93-102=6.9-9.1 volts (Low voltage)
• 115-124=8.5-10.7 volts (Norm band start)
• 215-225=15.8-18 volts (Norm band end)
• 230-241=16.9-19.1 volts (High voltage)

rhEo Displays the present hexadecimal value for the instrument cluster backlighting pulse width modulated (PWM) input to the HEC (used when requesting assistance from the hotline). rhi
rhS
rho PWM input duty cycle.
SCP hexadecimal dimming step (used when requesting assistance from the hotline).
Output driver counts in hexadecimal format (used when requesting assistance from the hotline). Cr Displays the present RUN/START sense input. Display will show -h with the ignition switch in the START position and -L with the ignition switch in the RUN position. ALtF Displays 8-bit hexadecimal value for alternate fuel level. Display will show a value between 00 and FF if the message is received. PA-PE7 Not used. GAGE Repeats test display cycle.
Turn the ignition switch to the OFF position or press and hold the SELECT/RESET button for 3 or more seconds and release to exit HEC Dealer Test Mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

You have a short somewhere in the instrument cluster

What year an make an model vehicle ?

If i may ask why did change the sensor,did it show the the ABS light on the cluster?You need to perfom a cluster self diagnosis am not sure of the procedure on Hyundai since i am a Nissan Tech or perfom active test on the cluster,if not check the fuses.Back to sensors if you had an ABS light before and it cleared but still no Speedo then you might have bought wrong sensors,the ABS module can tell that there is a sensor due to resistance but as you drive it can't pick up your speed signal to the ECM

The instrument cluster is a hybrid electronic cluster (HEC) with two basic configurations, the base cluster and the optional instrument cluster. In addition to the two basic configurations, the SVT uses a modified optional cluster in combination with a separate oil pressure and oil temperature cluster. The base instrument cluster, optional instrument cluster and the oil pressure and oil temperature cluster receive and output information utilizing both hardwired circuitry and the standard corporate protocol (SCP) or the controller area network (CAN) communication network (2.3L only). It is very important to understand:

• where the input originates from.
• all the information necessary in order for a feature to operate.
• which module(s) receive(s) the input or command message.
• does the module which received the input control the output of the feature, or does it output a message over the SCP or CAN network to another module?
• which module controls the output of the feature. Its more then likely you need a new instrument cluster.

You will have to replace your main computer module but can get a rebuilt one at dealership.

it could be both.but most likely cluster.scan the car while driving and check if scanner shows the speed .if it shows the speed that mean cluster is bad if it does not check the wiring and speed sensor in the transmission.thanks

put the car on an oscilloscope and check what is happening,check cranksensor,injectors,fuel pump supply,coil packs you will then see what you are loosing if its power(electrical)or a fuel problem put a fuel pressure gauge on it and road test it you will then see whats happening.........oscilloscopes dont tell lies.....

Check VSS Vehicule Speed Sensor wire may be corroted, bad connection or faulty; if 2wd the adaptor is located on the extension housing of the transmission (left side)
if 4wd look on transfer case extension (left side)

Good luck

if they arent working i would suspect a loose connection to the computer module or, a problem with the computer try scanning for any codes that there may be
