Motor Vehicle Maintenance & Repair Asked by C Rose on January 9, 2021
I am new to this site and found that someone has previously asked this question, but they did not indicate if they ever found a fix for the problem. Their post is here How Do Get My 2011 Hyundai Elantra Tachometer, Speedometer and Fuel Guage Display Working Again?
I am experiencing the same issue. I have a 2013 Hyundai Elantra which has been on the road since May 2012 and is about 6 months out of warranty and has around 55,000 KM on it (I think this is roughly 37,000 Miles) for a 5.5 year old car this is not much mileage.
In any case. Earlier this week my wife the primary driver of the vehicle noted that the speedometer, tach, and gas guage had stopped working. The speedometer and tach are ‘analog’ looking gauges bu the gas gauge is a digital gauge.
Upon checking further the odometer is not functioning and the trip meters are not incrementing. The average fuel economy is working, the temp gauge which is also digital is working. All idiot lights are working and light up as they should. The gear indicator is working. Cruise control works and the lights indicate it is working.
There is no sign of a check engine light being lit. So I presume no errors are being thrown. I found a post that mentions the vehicle speed sensor which is attached to the transmission as a possible option, which might make sense for the speedometer and tach but how does that sensor affect the fuel gauge? Plus if a VSS were to fail would that not throw an error code and cause the CEL to illuminate?
I’ve found other posts about pulling fuses or setting an on/off switch on the fuse panel to off for up to two minutes. I attempted removing and checking some fuses that appear to be related to the gauges; and I attempted setting the on/off switch to off for two minutes. The problem persists.
At this point I’ve seen this same problem described on a few different boards, but nobody has provided a specific fix. There have been suggestions, but not a specific answer.
In regards to the car, nothing has happened or has been done to the car. It had been sitting for 2-3 days last weekend (this being a Friday). We changed the tires to the winter set about a month ago. But this is a full set of wheels and tires which have been used on the car for 4-5 seasons now.
I believe this is everything. I’m trying to be as thorough as possible and provide as many details of what I have read and what my problems are.
If anybody else out in Internet land has found a solution, I would like to know what the solution was.
Thank you in advance for any answers you can provide.
Kind Regards,
Chris
Based on what I seen on the all knowing internet. It could be something as stupid as a bad ground connection. The module that controls the instrument cluster is the the BCM (Body Control Module). Where the bad ground connection is...God knows.
