On a2000buick century odometer not working


You would need to take it to the dealer or someother qualified repair shop that has the diagnostic tool to check for DTC'S - diagnostic trouble codes in the instrument cluster .
DTC B0570 Season Odometer Malfunction

The instrument cluster receives a vehicle speed input from the vehicle speed sensor (VSS) over the Class 2 line. This signal is used in order to drive the speedometer and the odometer of the instrument cluster. The instrument cluster will compare the VSS data with a 16-point look-up table in order to determine needle deflection. A smooth filter is used in order to secure a continuous response. The season odometer displays the total accumulated kilometers (miles) of the vehicle. This value is permanently stored in the Electronically Erasable Programmable Read Only Memory (EEPROM) of the instrument cluster. The trip odometer displays the accumulated kilometers (miles) to the tenths of a kilometer (mile) since the last reset. This value is stored in Keep Alive Memory (KAM) of the instrument cluster.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
Always perform the Instrument Cluster Diagnostic System Check before attempting to diagnose this DTC.
This diagnostic procedure requires using a scan tool.

2006 chevy Silverado Electric cooling fans do not come on. Replaced all relays. Checked the fans by hot wiring them to the battery and they function. Other than the PCM what else could it be?


Did you check the fuses, any voltage at the fuses? In the picture, the left side of relay is control, the pcm grounds the control side of relay. Any applicable trouble codes? Check the coolant temp sensor. I'm not saying replace anything. Will the fans come on if you turn on the ac?
The fans should come on around 220 degrees F. Some makes and models, if you unplug the coolant temp sensor, the fan/s may run all the time? The info I looked at was for 1500--5.3L engine--non-hybrid.

Need a wiring diagram of the 2 wires from the temp sending unit that controls the temp gauge and cooling fans on a 99 grand am gt. Need to see where they go They disappear behind the engine


The PCM regulates voltage to the coolant fan relays, which operate the fans. Refer to Engine Controls.

Engine Cooling Fan Description - Electric
The electric cooling fans are used to lower the temperature of the engine coolant flowing through the radiator. They are also used to cool the refrigerant (R-134a) flowing through the A/C condenser.
Operation
The electric cooling fan operates when the engine cooling temperature exceeds a certain value. The cooling fan on this engine is controlled by the PCM. The cooling fan has one speed. The PCM turns the cooling fan ON by grounding the coil of the cooling fan relay when certain conditions are met. When the A/C is requested, the cooling fan will also be turned ON.
Power for the cooling fan motors are supplied through Cool Fan #1 and Cool Fan #2 relays. The cooling fan relays are energized when current flows from the fuses in the Cell 23: Cooling Fan Controls , and through the relay coils to ground through the PCM. The Low Speed fans control circuit is grounded for low speed fans operation. During low speed fans operation, both fans run at a slow speed. The High Speed fans control circuit is grounded for high speed operation. During high speed fans operation, both fans run at high speed.
Important: When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. It is important to perform Powertrain On Board Diagnostic (OBD) System Check prior to diagnosing the engine cooling fans.
If a problem that involves the low speed cooling fan relay control circuit exists, DTC P0480 should set. If the problem affects the high speed cooling fan relay control circuit, DTC P0481 should set. A problem with the ECT sensor should set DTC P0117, P0118, P1114, or P1115. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Cooling Fan Diagnosis tables. The Cooling Fan Diagnosis tables should be used to diagnose the PCM controlled cooling fans only, if a DTC has not set.

The engine coolant temperature (ECT) sensor (3) is a thermistor, a resistor which changes value based on temperature, mounted in the engine coolant stream. Low coolant temperature produces a high resistance (100,000 ohms at -40°C) (-40°F), while high temperature causes low resistance (70 ohms at 130°C) (266°F).
The PCM supplies a 5 volt signal to the ECT sensor through a resistor in the PCM and monitors the terminal voltage. Since this forms a series circuit to ground through the ECT sensor, high sensor resistance (low temperature) will result in high PCM terminal voltage. When the resistance of the ECT sensor is low (high temperature), the terminal voltage will be drawn lower. This terminal voltage indicates engine coolant temperature to the PCM.
A hard fault in the ECT sensor circuit should set either a DTC P0117 or P0118. Remember, these DTCs indicate a malfunction in the engine coolant temperature circuit, so proper use of the DTC table may lead to either repairing a wiring problem or replacing the sensor, to properly repair a problem.

The engine coolant sensor is an input to the PCM , Two wire's both go to the PCM .An the PCM turns on the cooling fans !

DTC P0480 Cooling Fan Relay 1 Control Circuit
DTC P0481Cooling Fan Relay 2 Control Circuit
The Body Control Module (BCM) request the cooling fans. The BCM sends a Class 2 message to the PCM in order to enable the fans based on various inputs. Thebattery voltage travels to all three cooling fan relay coils. The PCM enables cooling fan relay #1 by providing the ground path. The PCM enables cooling fan relays #2 and mode control together by providing a ground path. The left and right cooling fans are connected in series. This will enable both fans on low speed when the fan #1 relay is energized. When all three fan relays are energized, both fans will operate at high speed. The high speed is possible because the fan relays are wired in a parallel circuit. When the PCM detects that certain DTCs are set, the PCM will enable the cooling fans.
The PCM will enable the engine cooling fans when certain Diagnostic Trouble Codes are set.

Important: A short to ground will cause an open fuse(s). Before performing this diagnostic procedure, inspect the fuse(s) for an open.

I have a 1999 Ford Focus Ghia. Neither the Air con fan nor the engine cooling fan are working. I've checked the fuses, and it's not those.


The engine temp will go up when it is loaded like a hill climb. Also the fan only is run when needed for the engine, it is computer controlled, so unless the engine is overheating at idle you are likely just not aware of how it is operated by the computer, the engine temp will be about 230F before the engine fan is turned on.. As far as the AC blower fan goes you need to pull the fan and see if it works when 12 volts is applied with a jumper. You can run an active system test with a factory scanner and it will test the fan operation.

I have a 2010 Chevy impala LS instrument cluster and it has a 20 pin plug I'm trying to figure out which wire's on the back of the cluster are for the speed sensor, rpm, gas, and temp wires.


Boy your way off base . All the gauges are inputs from the ECM - engine computer . The VSS - vehicle speed sensor , ETC - engine coolant temp sensor , sending unit in the fuel tank , All this sensors input the engine computer . The PCM then sends this info on the GMLAN serial data bus ,communications network . The Instrument cluster has a microprocessor inside that translates this info an controls the gauges. You probably have an instrument cluster problem or a communication network problem . Your best bet is to take your vehicle to the dealer or some other qualified repair shop. Need to have it checked for DTC'S - diagnostic trouble codes.

While driving antitheft light comes on and all the gauges go flat,car keeps runnig,want to disable system,not sure what to look for


Before doing something drastic ,have it checked out for DTC'S - diagnostic trouble codes . It may not be the anti-theft system ,gauges going flat would be more like a communication problem between modules . PCM / BCM / instrument cluster etc.. That also could cause theft light coming on . If your not sure what to look for ,take it to a ASE certified professional . You may render your vehicle useless if you don't know what your doing .
Serial Data Power Mode Master
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:
Serial Data Messages The modules that depend exclusively on serial data messages for power modes. stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data. If the engine run flag serial data is True, indicating that the engine is running, the modules fail-safe to RUN. In this state, the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to OFF-AWAKE. In this state, the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Indicators and Warning Messages
Refer to Indicator/Warning Message Description and Operation .
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the powertrain control module (PCM) or the engine control module (ECM). The IPC receives a serial data message from the PCM/ECM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 38?°C (100?°F) if:
?€¢
The PCM/ECM detects a malfunction in the engine coolant temperature sensor circuit.


?€¢
The IPC detects a loss of serial data communications from the BCM.

Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM) or the engine control module (ECM). The IPC receives a serial data message from the body control module (BCM) indicating the fuel level. The fuel gage defaults to E (empty) if:
?€¢
The PCM/ECM detects a malfunction in the fuel level sensor circuit.


?€¢
The IPC detects a loss of serial data communications from the BCM.

When the fuel level is less than 14 percent, the low fuel indicator illuminates.
Odometer
The instrument panel cluster (IPC) contains a season odometer and a trip odometer. Momentarily press the trip/reset switch 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 odometer is calculated and stored electronically in the body control module (BCM). The BCM uses the vehicle speed information from the powertrain control module (PCM) to calculate the odometer. The odometer displays 'error' if an internal IPC memory failure is detected. The IPC stores a backup copy of the odometer value incase the IPC stops receiving a valid odometer value from the BCM.
Speedometer

Tac and speedometer not working. What's problem?


Jeep XJ it is.
the Cluster is a computer. brain,
a stand alone display.
fuse 16 in PDC (cluster memory fuse)
and fuse 9 in JB . runs it. JB is cab fuse box.

so what works in the cluster, all things, but not speed or tacho.
engine runs ok
scan tool show no DTC errors.?
all warning lights in cluster work? at self test key?????

if the PCM can not comm, to the cluster, the cluster
can not show tach or speed, can't , and cant update odometer either
does the odometer roll moving>? i bet not

the cluster is a stand alone unit, with puter brain (processor)
fuel guage work?

if the scan tool shows U codes or C codes and comm errors
that must be addressed first. (cause)
see?
you cant fix cars, with out a $5 scan tool, cant. why not buy one
and use it?
ask how, 1000's of choices here... and more.

Need to know where the fan motor and resistor is located on the 2003 Ford Focus. Car overheats while idling, driving, in park, and it'll still overheat when the heater is on. Tell me what site I can find...


Cars usually overheat when the thermostat is faulty, coolant level is low, or the water pump fails. If your cooling fan on the radiator does not kick on shortly after the engine reaches operating temperature, you may have a bad cooling fan, cooling fan relay, or cooling fan fuse. If your engine is overheating, start by checking the fluid level, and installing a new thermostat.

A blower motor resistor is the device that controls a car's cabin heating and air conditioning unit's fan speeds. This usually won't cause the engine to overheat, your A/C fan may not function or only function at one speed.

Might be the same....You may want to do the diagnosis proceedure. Alot of times its the door actuators. Servos in replace of old cable design. Usually it will be a code 46. DOOR BLEND ACTUATOR SHORT TO BATTERY.
The DTC's can be checked with the MTC control and the Odometer Display of the Mechanical Instrument Cluster if a DRBIII® scan tool is not available. The MTC control can only be placed into the diagnostic mode while the engine is running and the vehicle is not moving. To place the system into it's diagnostic mode, adjust the MTC control to the following settings:
  1. The engine must be running with vehicle not moving.
  2. The fan speed set to any speed except OFF.
  3. The temperature control knob in full cold (full counterclockwise position).
  4. The mode control knob must be placed in Defrost position (full clockwise position).
  5. The A/C button can be On or Off.
  6. Press and hold the rear window defogger (EBL) button until the mechanical instrument cluster odometer display indicates an "AC00". The BCM will chime once and the MTC A/C button LED will begin blinking.
  7. Release the EBL button and wait until the MTC A/C button LED stops blinking. This means that the error check and climate control door calibration is complete. NOTE: It is important that no other control knob or button is pushed until all DTC's are read. Pushing any button except the A/C button or turning a control knob will end the diagnostic test without showing the rest of the DTC's. There also may be other DTC's stored in the BCM not related to the climate control system. These DTC's can only be found using the DRBIII® scan tool.
    DTC's related to the MTC control head will appear on the odometer display in numerical form after the letters "AC". The odometer display will return to normal operation if no DTC's are found. If a problem is found, then the odometer will display the letters "A/C" followed by the DTC number. The odometer display can only show one DTC at a time. Under certain circumstances, more than one DTC could be in the memory. To scroll through any additional DTC's, press the A/C button on the MTC control. The BCM will beep each time the A/C button is pushed. Continue pushing the A/C button and recording the DTC's until the odometer returns to normal operation (note the letters AC will dissapear.
