Question about 1998 Nissan Sentra

1 Answer

Dashbord instrumentation Non functional for Japan imported FB14 Sentra

My dashboard instruments gone crazy
1. Tachometer hovering around 1000 RPM once the car is started.
2.Speedometer non functional
3.Fuel gauge showing full indication at all times
4.Temperature gauge showing High temperature once car is started.

This problem started and it sometimes work normal, all lights on dashboard working, even when the fuel goes low. any suggestions, i think its a ground fault causing it. please advice.
I was told that The lights are on a seperate circuit. The dash gauges have a transformer that steps down the 12 volts to something like 9 volts. My bet is the transformer is going out. The solution is to get that part replaced by a speedometer shop or get another one from a wrecking yard.

What i need to know is exactly where is this transformer located and if you can help with supplying a drawing to assit in repair

Located behind the instrument cluster
It is attached to the rear panel of the cluster.
input from battery is 10Volts, it regulates down to 5Volts
Any higher voltage inputed will overload the capacitors and resistors will burn,
Also check power distribution center, under hood upper motor area in drivers corner, check all relays and fuses.
Before you rip in to the dash check all ground wires, battery to ground, harness grounds, driver/passenger mid fram rail, Fuel sender is also ground to top of gas tank. IF ALL gauges do not work, that just leaves voltage regulator and/or cluster is malfunction,

SOURCE: Instrument Gauges (Fuel, Speedometer, etc.) No longer Light Up

Hi ahcobras. Did you check that the dimmer switch hasn't accidentaly been turned to the off position? You don't say what car it is on, but as it has cruise control, it probably has a dimmer switch! Instrument lights don't usually have a seperate fuse......

2004 navigator rpm mph gauges quit working

The instrument cluster receives the vehicle speed sensor (VSS) signal from the PCM through the SCP communication network. The instrument cluster micro-processor monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.

The instrument cluster receives the tachometer data from the PCM through the SCP network and commands the tachometer according to the data.

Taking your vehicle to a qualified repair shop that has diagnostic tool to scan the instrument cluster for DTC'S - diagnostic trouble codes an also view sensor input data to the PCM engine computer an the I/C would be your best bet .

Speedometer works but not the rpm gauge 98 Tahoe 5.7

The speedometer is operated differently then the tachometer. Tachometer
The tachometer displays the engine speed in revolutions per minute (RPM). Voltage pulses are taken from the ignition control module (ICM) (Gasoline) or the generator (Diesel) and sent to the tachometer. Solid state circuits convert the pulse frequency in order to move the pointer of the tachometer.

Tachometer Inoperative (Gas)

Tachometer 1997 pathfinder erratic RPM

I just solved this problem on my 1997 with 183K miles . First I checked all of the following:1) sensor on distributor; 2) wires from distributor to back of instrument cluster; 3) connections of wires to instrument cluster; 4) 4 screens going through the soft circuit board to tachometer; 5) the SOLUTION- I removed the tachometer from the instrument cluster and looked at the hard circuit board of the tachometer. On one side there is a plastic square housing about 1/4 x 3/8" soldered to the circuit board that has a plastic screw facing out. it was lose, so I tighten it and now my tachometer is OK. A simple test to check for this type of an error is hit your dash when the tachometer is erratic. if you see a fluctuation based on the tap on the dash you either have a lose connection of some type like this one. Fix is easy, once you have the instrument cluster out you only have to remove the four screws on the back of the cluster holding the tachometer in place. Remove the tachometer carefully and tighten the plastic screw being careful not to over tighten.

Tachamererter intermit dont work

Tachometer failures are very common on this brand. The tach will tend to hop around first and then just stop.
The most common failure for this concern is a faulty tach in the instrument cluster. This can be checked by using a scan tool to observe the instrument cluster data for the r.p.m. signal, if the scan tool shows a tach signal (RPM) signal then the instrument cluster isn't displaying this signal and is faulty and needs replaced or repaired.

Hope helps.

While the car is not running tachometer stays at maximum RPM even with battery unhooked. As the car is running tachometer trys to flutter down to lower RPM. Would this be wiring problem or instrument...

Sounds like a instrument problem. If you remove power at the battery then it should not have power to keep it at the high RPM level. There's nothing there in induce the RPM to range.

Changing dashboard light


This solution will be of great help to you,even in the case of future or other dashboard problems;
Instrument cluster consists of electronic analog gauges, various warning lights, and optional tachometer. Vehicles equipped with tachometer have an electronic vacuum fluorescent transmission range indicator (PRND3L),odometer and trip odometer display. Vehicles without tachometer are equipped with a cable-operated transmission range indicator.
Instrument cluster is equipped with the following warning lights:
Battery voltage.
Cruise (speed control).
Door ajar.
Fasten seat belt.
Lift gate ajar.
Low fuel level.
Low windshield and washer level.
Traction Control.
The Body Control Module (BCM), which receives input from various sensors, sends display information to instrument cluster and operates gauges. Instrument cluster incorporates a self-test diagnostic feature to identify electronic problems. BCM, Powertrain Control Module (PCM), and Transmission Control Module (TCM) are continuously monitored by the diagnostic system.

With ignition off, press and hold TRIP and RESET buttons while turning ignition switch to ON position. Continue to hold TRIP and RESET buttons until odometer window displays CODE (approximately 5 seconds). If problem exists, system will display diagnostic trouble codes. See DIAGNOSTIC CODE CHART table. If no problem exists, Code 999 (end test) will be displayed.
110.......Cluster Memory Fault
111.......Cluster Calibration Fault
905.......No CCD Bus Message From TCM
921.......Odometer Fault From BCM
940.......No CCD Bus Message From PCM

After diagnostic code display ends, instrument cluster will go into each of the following tests in order:
Dim test.
Calibration test.
Odometer segment test.
Electronic Transmission Range indicator segment test.
Dim Test
CHEC-0 will be displayed in odometer window. Instrument cluster will dim Vacuum Florescent (VF) display. If VF displays do not dim, a problem in instrument cluster exists. See BODY CONTROL COMPUTER TESTS in BODY CONTROL COMPUTER article.
Calibration Test
CHEC-1 will be displayed in odometer window. Each of instrument cluster gauges will move sequentially through each calibration point. See GAUGE CALIBRATIONS table. If gauge needle is not calibrated properly, a problem in instrument cluster exists.

Odometer Segment Test
CHEC-2 will be displayed in odometer window. Each segment of odometer will light sequentially. If any segment does not light, replace instrument cluster.
Electronic Transmission Range Indicator Segment Test
CHEC-3 will be displayed in odometer window. Each segment of electronic transmission range indicator will light sequentially. If any segment does not light, replace instrument cluster.
