I gave a 2006 Hyundai Accent and recently the whole instrument cluster shuts down then back on intermittantly whilst the vehicle is driving. It has been checked out by an autoelectrician who tells me that the problem lies with the cluster and not the wiring coming to the cluster. Any suggestions as to what the problem could be would be appreciated.

Try to buy the New one and test is going to give

Best website I came across for manuals.. Very helpful website

Pull the fuse and put it back in, first. Then pull the plug on the back of the IP and put it back in. It is intermittent. These will usually fix the problem... Corrosion.

Speedometer
The speedometer is an analog gauge that is located in the instrument cluster. The PCM/VCM receives an analog input from the vehicle speed sensor and converts it to a digital signal containing 4,000 pulses per mile (PPM) for the instrument cluster.
The PCM/VCM sends this digital output (4,000 PPM) to the instrument cluster on a designated circuit. These pulses can be measured in Hertz (Hz) using a digital multimeter (DMM) on the AC scale. The PCM/VCM calibration is matched to the final drive and tire size of each vehicle. If the final drive or tire size is changed for any reason, the PCM/VCM must be updated in order to match the new final drive or tire size. If not, the signal will not be accurate for proper speedometer/odometer operation. An incorrect signal can affect the antilock brakes and the cruise control systems.
The speedometer system consists of the instrument cluster, vehicle speed sensor (VSS), PCM/VCM and related wiring. The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the PCM/VCM. The VSS mounts to the transmission tailshaft extension housing on 2-wheel drive (2WD) models and the transfer case output shaft housing on 4-wheel drive (4WD) models.
Repairs to the instrument cluster can only be performed by an authorized instrument cluster service center.

Diagnostic Aids
• An intermittent in the vehicle speed sensor (VSS) circuit may cause an inaccurate speedometer. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
• Check for the following DTCs:
- DTC P0502 Vehicle Speed Sensor (VSS) Circuit Low Input and DTC P0503 Vehicle Speed Sensor (VSS) Circuit Intermittent in Automatic Transmission - 4L60-E
- DTC P0500 Vehicle Speed Sensor (VSS) Circuit in Engine Controls - 4.3L

Important: If the instrument cluster is completely inoperative, refer to Instrument Cluster Inoperative .
Install a scan tool.
Raise the vehicles drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
Start the engine.
Place the transmission into drive for automatic transmission and third gear for manual transmission.
Compare the displayed vehicle speed on the Instrument Cluster with the monitored speed on the scan tool.
Does the vehicles speedometer and the scan tool both display 0 km/h (0 mph)?

Turn OFF the ignition.
Disconnect the in line connector C101.
Turn ON the ignition.
Test the vehicle speed output (4K) circuit voltage from the in line connector C101 (female side of connector) to a good ground using the DMM J 39200 . Refer to Circuit Testing in Wiring Systems.
Does the DMM display a voltage greater than the specified value?

have you ever used a diagnostic trouble flow test chart ? Let me know if you make it this far and then I will send the last 9 steps . It's either a wiring problem or instrument cluster or PCM is bad . And if the PCM is replaced it will need progamming . Dealer only .

check to see if the Instrument Cluster fuse is ok

Hi Shannon

To remedy this, check to see if the dash fuse is the right amperage, the likely cause of this is a dead short in that department.

Have you fitted a stereo system recently? - check the wiring behind the instrument cluster for either a lose connection, or a open wire (live wire) shorting to ground. Lastly check to see if you have a proper ground as well

Hope this helps

Do you have a professional scanner ,do a scan of the whole vehicle . Instrument cluster , BCM , etc... Not OBD2 scan from autozone or advance etc.... thier tool can't check the whole vehicle network . The control module's on your vehicle all share information on what is called a serial data bus ,or communication network. ( temperature guage not working- sending unit keeps blowing, ) I don't think the sending unit is the problem , an it's not a sending unit . It's a engine coolant temperature sensor ,an it's a input to the PCM/ECM - engine computer . The engine computer send's this info. to the instrument cluster on the GMLAN data network . GM had problem's with stepper motors in the instrument clusters . The stepper motor control's the gauge needle.2003 to 2006

Also sounds like you have wiring harness issue's ,finding an viewing wiring diagrams an using a DMM - digital multi-meter to test affected circuit's is the way to a fix. Not guessing !

there is a wiring package that contains a wiring connector for the back of the cluster.the part number is 5016261aa
