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.
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 engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The IPC receives the coolant temperature information via serial data message from the body control module (BCM). The engine coolant temperature gage defaults to 60?°C (140?°F) or below if:
?€¢
The ECM detects a malfunction in the engine coolant temperature sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The body control module (BCM) sends the fuel level information from the ECM to the IPC via a serial data message indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The ECM detects a malfunction in the fuel level sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the BCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The IPC contains a season odometer and trip odometer A or B. Momentarily press the trip/fuel button in order to toggle between the season odometer and the trip odometer. Press the set/reset button for greater than 0.25 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 engine control module (ECM). The IPC calculates the mileage based on the serial data vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers and can be set through the customization menu in the driver information center (DIC).
PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRNDL display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

?€¢
The IPC detects a loss of serial data communications with the body control module (BCM).
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM). The IPC calculates the mileage based on serial data vehicle speed information from the ECM. The IPC receives vehicle speed information from the body control module (BCM) via a serial data message. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of serial data communications with the ECM or BCM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine speed. The IPC receives the engine speed information from the body control module (BCM) via a serial data message. The tachometer will default to 0 RPM if:
?€¢
The ECM detects a malfunction in the engine speed sensor circuit.

?€¢
The IPC detects a loss of serial data communications with the ECM.

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

How can I fix a no crank problem on a 003 Cadillac Cts?


Did you have the vehicles modules check for DTC'S - diagnostic trouble codes ? That's the place to start . See if a professional grade scan tool will communicate with all the modules on the vehicle > Without knowing if all modules are communicating on the class two serial data bus , you would be wasting your time testing thing's ,without knowing what is going on ,How the starting system works !
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM) to command starting. Battery voltage also travels through the switch side of the Run/Crank relay then through the clutch switch, if equipped with manual transmission, and on through the coil side of the Starter relay and then to the ECM. The ECM receives class 2 information from the vehicle theft deterrent (VTD) and transmission control module (TCM) to verify that all parameters are met for starting. When all parameters are met the ECM grounds the control circuit of the Starter relay closing the switch providing battery voltage to the starter solenoid through a 30 A Maxi-Fuse.
I wouldn't think the ECM was bad , but you never know ! With a factory scan tool or a professional one you could check inputs to the ECM , is it receiving the proper inputs to initialize starting . Does you caddy have automatic transmission ? If it does there is the park neutral switch to think about . You can go to http://bbbind.com/free_tsb.html for free wiring diagrams ! Go to youtube an watch a few videos on basic automotive electrical trouble shooting , If you don't know about that sort of thing . An how to read wiring diagrams etc.. Find the ECM on the vehicle an check to see if it is receiving 12 volts from the ignition switch . Check for voltage at the starter relay too !
The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. This serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps. This value is an average, class 2 uses a variable pulse width modulation to carry data and depending on the message it may operate faster or slower. The bus will float at a nominal 7.0 volts during normal operation. Each module can pull this lower during the transmission. The bus is not at battery positive voltage or ground potential during normal operation. When the ignition switch is in RUN, each module communicating on the class 2 serial data line sends a state of health (SOH) message every 2 seconds to ensure that the module is operating properly. When a module stops communicating on the class 2 serial data line, for example if the module loses power or ground, the SOH message it normally sends on the data line every 2 seconds disappears. Other modules on the class 2 serial data line, which expect to receive that SOH message, detect its absence; those modules in turn set an internal DTC associated with the loss of SOH of the non-communicating module. The DTC is unique to the module which is not communicating, for example, when the inflatable restraint sensing and diagnostic module (SDM) SOH message disappears, several modules set DTC U1088. Note that a loss of serial data DTC does not normally represent a failure of the module that set it.

My 2004 Saturn ion 3 has 2 codes coming up u2105 p0700 an it won't go in drive or reverse what could it be


First off you need to understand your vehicle has several control modules on board . The PCM - engine computer , TCM - transmission control module , SRS - air bag module , Anti theft , antilock brakes , An these modules all are able to talk to each other on a communication network , On your vehicle it happens to be the CAN data bus !
The transmission control module (TCM) uses the controller area network (CAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure that affects emissions has occurred in the transmission control system. When the ECM receives the correct message from the TCM, DTC P0700 will set.
Which transmission does your vehicle have ?
Automatic Transaxle AF23-5
OR
Automatic Transmission VT25-E
DTC U2105-U2199
The controller area network (CAN) serial data line is a high speed serial data bus used to communicate information between the engine control module (ECM), body control module (BCM), and the transmission control module (TCM). Typical data-transmission speeds must be high enough to ensure the required real-time response is maintained. The CAN serial data line does not communicate with the scan tool via the data link connector (DLC). CAN serial data information is interpreted by the BCM and transmitted to the serial data line by the BCM.
I suggest you take this to GM dealer or some other ASE certified repair shop .

I have a 03 Saturn Vue that has electrical issues sometimes it dose not start and I have to remove the ignition and main battery fuses to get it to start. Up cluster works when wants along with dash lights...


Sounds like you mite need an ignition switch. But just to be sure you should have the modules scanned for codes , especially the body control module ! Are any warning lights staying on ,check ENG , A symbol of a wrench lit up or a picture of a lock symbol ? This car has a few electronic control modules and there all talk back an forth on a serial data bus . This car has two !
Class 2 Data Line
Saturn utilizes the class 2 communications system for most vehicle system controllers that must exchange data and commands. Class 2 data is pulse width modulated. The pulse width modulation of class 2 data allows better utilization of the data line.
The messages carried on class 2 data streams are also prioritized. This means if 2 devices try to communicate on the data line at the same time, only the higher priority message will continue. The device with the lower priority message must wait. The modules on the class 2 data line are:
?€¢
Body Control Module (BCM)


?€¢
Power Steering Control Module (PSCM)


?€¢
Instrument Panel Cluster (IPC)


?€¢
Inflatable Restraint Sensing and Diagnostic Module (SDM)


€¢
Vehicle Communication Interface Module (VCIM), if equipped Controller Area Network (CAN)
The controller area network (CAN) serial data line is a high speed serial data bus used to communicate traction information between the electronic brake control module (EBCM), the engine control module (ECM), the body control module (BCM), and the transaxle control module (TCM). Typical data-transmission speeds must be high enough to ensure that the required real-time response is maintained.
The addressing scheme employed with CAN assigns a label to every message, with each message receiving a unique identifier. The identifier classifies the content of the message, such as engine speed.
Each module processes only those messages whose identifiers are stored in the module's acceptance list. This is CAN's form of message filtering.
The identifier labels both the data content and the priority of the message being sent. Each module can begin transmitting its most important data as soon as the bus is unoccupied. When more than one module starts to transmit simultaneously, the message with the highest priority is assigned first access. A module responds to failure to gain access by automatically switching to receive mode. The module then repeats the transmission attempt as soon as the bus is free again.
You need to have a professional scan tool to check for codes in the modules other than the engine ecm module. I have seen a bad instrument cluster short the bus and cause the vehicle shut down . hope this helps ! First place to start is checking for codes in all the modules. If there is a problem with one of them ,it usually sets a code in one of the other modules !

P0606
Control Module Internal Performance

P0601
Control Module Read Only Memory (ROM)
ECM, PCM
U0107
Throttle Actuator Control (TAC) Module Serial Data Circuit
ECM, PCM

The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate using a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity but also adequate system voltage. This diagnostic monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM detects a loss of data or invalid data, or if the throttle limit is exceeded while operating in the Reduced Engine Power mode, DTC U0107 sets.

Your best bet is going to be to take your vehicle to a GM dealer ! Cadillac , Buick
