Doesnanyone have a diagram showing where the wires on a speedometer connect to? I need to see if i pulled it on accident. And fuel gauge. Im learning so pictures are easier. Thx 2001 chevy tahoe


The speedometer gauge is controlled by information sent over the class 2 data bus from the PCM/ECM - engine computer . There is a VSS - vehicle speed sensor mounted on the transmission , this VSS is a input to the engine computer .
Speedometer
The IPC displays the vehicle speed based on the vehicle speed signal from the PCM. The IPC- instrument panel cluster receives the vehicle speed signal via a discreet wire. The IPC uses the vehicle speed signal circuit (4000 pulses/mile) from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit (4000 pulses/mile) exists.
Is the whole instrument cluster dead ?
Fuel Gauge
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 gauge 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 a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to:
• Fuel System Description in Engine Controls - 4.3 L
• Fuel System Description in Engine Controls - 4.8 L, 5.3 L and 6.0 L
• Fuel System Description in Engine Controls - 6.6 L
• Fuel System Description in Engine Controls - 8.1 L
Hourmeter
The IPC can display the accumulated engine run time hours using the VF display when the cluster is in the LOCK or ACC position. The IPC stores the accumulated engine run time hours in a non-volatile format. The accumulated hours will not change if the battery was disconnected or removed. When the ignition is OFF and the trip reset switch is pushed in and held for more than 4 seconds, the IPC will display the accumulated hours for 30 seconds. The hourmeter will reset to 0.0 when 10,000 hours are accumulated.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 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 signal circuit from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer can be configured to display either miles or kilometers.
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 blanks if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park (open input).
• The IPC detects a loss of class 2 communications with the PCM.
GM had problems with stepper motors that control the needle position .
Your best bet buy a used instrument cluster from the auto slavage yard .

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.

Why my 1998 range rover 4.0 se won't start unless I use starter fluid. It will only turn over without it.


did you hit a big bump when it stopped? you may have a fuel emergency shut-off switch that tripped or a blown fuse.

Fuel gage showing half a tank but trip computer only registering 60 miles left


Its very simple. If the gauge is showing half full then fill the tank and see how much fuel it takes. If the amount you add is approximately 50 percent of the fuel tank capacity then you know the fuel gauge is accurate . In that case the computer is giving an inaccurate reading and should be ignored. All you need is an accurate fuel gauge - it does not matter a row of beans what the computer says if the fuel gauge is reading correctly.

Hey, was wondering what the message center display symbols and what they mean, lost my manual


There are five trip computer displays which may be stepped through by pushing the MODE button. The information will appear in the following order:

D AVG ECON (Average Fuel Economy): This shows the average fuel economy since the last reset.

D INST ECON (Instantaneous Fuel Economy): This shows fuel economy for the most recent second of driving.

D RANGE (Trip Range): This shows the estimated distance that can be traveled with the remaining fuel. The fuel economy used to calculate range is based on the last few hours of driving. When in a low fuel condition, LO is displayed.

D FUEL USED (Trip Fuel Used): This shows the accumulated fuel used since the last reset.

D AVG SPEED (Average Speed): This shows the average speed since the last reset.

04 avalanche- suddenly windows, locks, radio and heated sets dont work, dash board shows airbag light, charge light check engine light,fuel gauge not working,oil change message indicator shows 0 zero oil...


Check for fuses and fusible links that may be tripped or blown.

Next, check for grounding issues someplace easy to reach like the heated seat connectors.

Most dummy lights work by choosing the warning light path over the circuit path when the circuit path is higher resistance. Which may explain your dash warning lights.

So, what I am trying to say is...you are looking for a open ground in a big big place....like under the hood at one of the major fuse/relay/fusible link points.

Check it out. Good luck and be careful.

91 deville fuel gauge flashes "E"


It seems that you are low on fuel based on you saying 70 miles in the range gauge. If this problem does not happen with 3 gallons of fuel or more then it is normal. The range is calculated on your average MPG and gallons of fuel in the tank. When the car gets to around 2 gallons it does not chance miscalculating your miles to empty and leave you on the side of the road. At this point he tank will read "E" to let you know it is time to fuel up. The flashing "E" is simply cadillac's way to get your attention that you are in fact low on fuel and need to take action. Hope this helps.
