My gauges quit working on my 2000 Ram 1500 and while troubleshooting the problem I removed the DIN plug located in the fuse box underneath the hood. It is the one with a phillips head screw in it. I examined the conenectors and everthing appeared in order. I reseated the plug and tightened the screw back up. I cranked the truck and everthing worked perfectly. I suspect that the connectors may work loose over a period of time and noticed that when tightening the screw it made a slip when overtightened much like a locking gas cap. Tighten the screw until just before it slips. Hopefully this will help a lot of dissapointed Dodge owners.

Hi my name is Allen!

Before doing any of the repairs below unplug the Crank Sensor and look at the cluster and see if everything works, if it does replace the crank sensor, if not read on.

The instrument cluster for that year is the BCM "Body Control Module" Which is the most likely cause for this problem, but keep in mind that another module gone bad can also bring down the BUS. Here is what you do, unplug each control module one at a time and see if the BUS comes back, unplug one look at the cluster to see if it comes back to life. If after unplugging each module and the cluster is still down then the most likely repair is replacing the cluster.

For further asistance you may reach me at FixYa!

My 2000 Dodge Stratus's speedometer has either not worked or has intermittently worked for the past two years. If it works, it will work for a bit and then drop back to zero.


Have your replaced the gauge ? (instrument cluster ) Do you know how it works ? Do you know what Chrysler CCD serial data communication is ? All the modules ,including the instrument cluster , PCM , BCM , share info on this data bus . The sensors you replaced are inputs to the PCM . The PCM sends this info on the data bus for the other modules .If your vehicle runs an shifts good it's not the sensor or the data bus ,if there was a problem with the data bus you would see a message on the instrument cluster NO BUS . You need a new cluster ! http://www.cnblogs.com/shangdawei/p/3570499.html

None of my gauges are working ion my dash


Intermittent gauges usually mean a bad ground connection for the gauges. Things to check: look for multiple ground connections at one screw to chassis frame & tighten it; check large connector at rear of instrument cluster for good connection; replace gauges fuse - it can be cracked. If none of those work, than instrument cluster circuit board will probably have to be replaced - which means removing the cluster.

A no bu5 message appears on the dashboard


that message is probably "no bus" which means the instrument panel is not communicating with the body computer or engine computer.
It could be a bad connection in the wiring or a problem with the cluster.
You can do an internet search for "no bus" for details.

No bus on my instrument cluster


(bus) = the connection between your cluster and the computer. If the truck starts, clean your ground connections and unplug the harness from the gauge cluster. In simplest case there is a connection that is rusted/ corroded/ or not tight enough.
(headlights) may have a delayed shut off followed with an automatic turn on sensor

No Bus Error


All the modules are connected together to communicate with each other via the PCI bus. It is possible that one of the modules is pulling the bus down.Since the vehicle won't start it could be any one of the modules. It will be a process of elimination to find the faulty one by disconnecting them one at a time. Here are a few, powertrain control module (the one you replaced) Instrument cluster, overhead console, anti-lock brakes, airbag. Since the cluster unplugged wont read anymore, just try to start the vehicle to see if that was the one. Otherwise see if the odometer message of "no bus" goes away after each one is unplugged.

Intermittant instrument cluster


The body controller (BCM) must send a message to the engine controller (PCM) to tell the PCM that it's OK to start and run when a theft system is involved. As long as the OK-to-run signal can make it to the PCM, all will be well.

But during the times when the gauges are flat, the bus communication system is probably crashed and there's no way to deliver the message. The PCM has no recourse but to disallow fuel at that point, killing the engine. The only thing that doesn't fit is that the starter isn't taken away at some point, but it may be something that doesn't happen in every model year.
The solution is with the communication bus, the CCD. It operates on two circuits, 2.5 volts each and connects to every module on the van that needs to share information. The instrument cluster printed circuit board is actually much more than just a board, it's a processor in its own rite. It controls gauges, telltale bulb illumination and supports the CCD bus both through voltage regulation and supplies the point of circuit termination (ground). The termination seems to be the key. Without ground, the bus voltage is pushed far above its normal 2.3 to 2.5 volt range, into the 7-volt area. Bus communication depends upon a voltage matrix very close to 2.5 volts, so this effectively crashes the network. Everything becomes a zero. One very good diagnostic tool for when the system crashes is to apply a firm, open-palm slap to the dash just above the instrument cluster. Works almost every time. While the problem can be temperature related (parked in sun), a good jolt usually brings it back online and allows the van to start and run. It seems ham fisted but it's almost impossible to diagnose by disassembly. The act of touching the area around the cluster normally brings it back and you're faced with the question of whether it was coincidence or not. I prefer the slap. Testing the data link connector (DLC), the trapezoid-shaped connector under the left dash area, will tell you if the bus is crashed or not. The third terminal from the left on each row (8 apiece) is CCD bus. Remember that 2.3 to 2.5 volts is normal while the key is on and the bus is active. You should see the voltage dancing, varying rapidly in response to data transmission if tested with a digital voltmeter. Anything above this is likely to be FAR above, indicating a slap is at hand... you know what I mean. The board isn't cheap... close to $450 and it requires a calibration before the tach or speedometer will operate. This may involve a trip to the dealer; I'm not sure if aftermarket scan tools can accomplish this task. Labor to install a board can also vary according to your repair facility.

INSTRUMENT CLUSTER IS READING NO BUS AND NONE OF THE GAUGES ARE WORKING


The red electrial connector on the main circuit board (of instrument cluster panel) has one and/or several soldered pins that have broken away or become loose at the soldered area. The soldered connections may look o.k., however, under a magnifying glass you can see a circular crack all around the protruding soldered pin. Fire up the soldering iron- use a fine point, add a tad of new rosin core solder and fix the crack. There may be trouble codes associated with this condition: P1695 and/or P1698; when you go to pull the Instument cluster out of the dash, jiggle to wire connector at the back of the IC with key 'on', and look at the odometer; if it flashes on/off, this is most likely the problem
