Durango error in odometer window - nobu5


Hey Gord,
Try disconnecting your CPU for about 3 to five minutes, this will reset your CPU. Then see if it starts. Note. there is probably a faulty microswitch somewhere causing your CPU to overheat and cut everthing off (No BuS). Try keeping it cold with a zip-lock bag of ice (keep your CPU dry). Your Durango should work as long as you keep the CPU is cold.

My mph, gas, and temp gauges are not working


That's why you don't let you husband work on your car ! Unless he does it for a living .. For MPH there is a VSS - vehicle speed sensor , for the gas there is a sending unit in the fuel tank, for the temp. gauge there is a temp. sensor located in coolant stream on the engine .You more then likely need to have you instrument cluster repaired . GM had a problem with step motors inside the instrument cluster . A step motor is what controls the individual gauge. The sensors are all inputs to the PCM - powertrain control module (engine computer ) .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to C or below if:
?€¢
The PCM detects a malfunction in the engine coolant temperature sensor circuit.


?€¢
The IPC detects a loss of class 2 communications with the PCM.

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The PCM detects a malfunction in the fuel level sensor circuit.


?€¢
The IPC detects a loss of class 2 communications with the PCM.

When the fuel level is less than 14% (84ohms), the low fuel indicator illuminates.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily press the trip select/reset switch in order to toggle between the season odometer and the trip odometer. Press the trip select/reset switch for greater than 1.5 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed information from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected.
PRNDL Display
The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display shall flash all gear positions if:
?€¢
The PCM detects a malfunction in the transmission range switch circuit.


?€¢
The IPC detects a loss of class 2 communications with the PCM.

Speedometer
The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses per mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 mph (0 kph) if a malfunction in the vehicle speed sensor circuit exists.
Tachometer
The IPC displays the engine speed as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine speed. The tachometer will default to 0 rpm if:
?€¢
The PCM detects a malfunction in the engine speed sensor circuit.


?€¢
The IPC detects a loss of class 2 communications with the PCM.

How to fix 1999 jeep cherokee sport


You mean it cranks but does not start, right ?
The NoBus on the display means the cluster is not talking to the computer. That could be a wiring problem or a component problem.
Have you checked the engine computer for trouble codes ?

Gauges dont work and stalls while driving


Although your question is unclear, I think you are trying to say that the vehicle is stalling out, and that you have an error on the dashboard display saying "NOBUS."
The "NOBUS" error means that the dashboard display is not receiving data from the main computer.
First, check that your GROUND BUS CABLE and GROUND STRAP are in good condition and making good contact. If the grounding is good, your main computer has failed, or the main computer connection is loose or dirty. ALSO, CHECK TO BE SURE THAT YOUR MAIN COMPUTER MODULE HAS GOOD GROUND.

My speedometer is not reading my speed! My accelaration and the power to go is completely there. If I'm on the freeway or parked, gauge says that I'm still going 25 mph. The gauge does move, but is FAR...


If the odometer is correct, the problem is in the speedometer head. If the odometer is also not accurate, it may be the speed sensor in the transmission.

Speed Odometer and Oil Gauge Drops


GMC yukons are notorious for gauge malfunctions, there are recalls for some models
However, if you have recently changed your battery this problem can occur and will take some driving time 30 min-60 min for the computer to fully reset.

No BUS on odometer


I used to have the NoBUS show up on the odometer also, but always while driving. The immediate fix was a sharp rap on the top of the cluster with my fist. To fix it permanently, I removed the cluster,cleaned the contacts both cluster and harness with spray contact cleaner, then applied some dielectric grease to prevent any further corrosion.
