2006 explorer dies did crank and crank replaced fuel pump and starter now when starting instrument pannel goes blank


The first thing to do would be to have it checked for DTC'S - diagnostic trouble codes . Not at auto zone , thier diagnostic system can not pull codes from BCM - body control module or from the instrument cluster . Are you familiar with C.A.N . - controller area network ? All the control modules on your vehicle talk to one another on a serial data bus or network . Your vehicle has a number of these modules , PCM - engine computer , SJB - smart junction box , air bags , ABS , An someothers . All the instrument gauges and the lighting happen over this data bus .
How to Diagnose Controller Area Network CAN Your best bet mite be to take it to the dealer or some other qualified repair shop .

Hi...
The code U1120 on DODGE,JEEP.CHRYSLER, PLYMOUTH.

The Defenition for this code is ; Lost Wheel Speed message.

Is related to a loss of speed comunication on the ABS Module.
And the ECM. Over the CAN C BUS.

Possible Causes. Can c bus, Open circuit or shorted.
Anti-lock Brake Module. Damaged. normally this happend when the car had an Accident. and is scrached.
On Rare Cases the ECM defective or desprogramed.
And some times Come As a Result of giving jump cables to start the Vehicle.

I hope this help on you question.
Thank you for use fixya.........

My speedometer and cruise control stopped working on my 2000 dodge durango I replaced engine speed sensor and that did not fix problem. Any suggestions?


What engine speed sensor ? Location ? The vehicle speed sensor signal comes from the anti-lock brake control module , to the PCM -engine control module . Speed Information to the instrument cluster comes from the PCM on the CCD serial data bus , Suggest you google Chrysler CCD data bus . Are any warning lights lit on the instrument cluster ? ABS , Check engine etc... Sorry but I suggest you take your vehicle to a qualified repair shop that has the diagnostic tools to find the problem . http://www.cnblogs.com/shangdawei/p/3570499.html

Why won't it start?


What year , make an model vehicle . The first thing I would do if this vehicle come to my shop would be to hook up a scan tool . I realize you probably don't have , that's why I suggest you have it towed to a ASE certified repair shop that does. You need to be aware of how all modules are intertwined on a serial data bus . Google that for your make vehicle . GM class 2 data bus an now all new vehicles have C.A.N - controller area network . You have modules for the airbags , ABS , BCM , PCM ,TCM , heater control panel , blower motor module ,lighting control module etc... All it takes is one module to have a problem to bring down the bus ,causing no start problems .

I have multiple codes instrument cluster codes: u1073, u1262, u1059, u1123, u1041; ABS/TCS codes: u1073, u1262, C1805, B2900;


Did you change any modules on the vehicle ?
B2900 VIN Mismatched ABS Module VERIFY that the module has the correct as-built data.
CHECK for correct powertrain control module (PCM) and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the C1805 Mismatched PCM and/or ABS/TC Module ABS Module CHECK for correct PCM and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the self-test. U1073 SCP (J1850) Invalid or Missing Data for Engine Coolant PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1262 SCP (J1850) Communication Bus Fault Network Fault REFER to Section 418-00 . Can a scan tool communicate with all the modules on the vehicle ?
  • The anti-lock brake system (ABS) module or stability assist module (if equipped) does not respond to the diagnostic tool
  • Circuit or connection in the standard corporate protocol (SCP) network.
  • ABS module.
  • Go To Pinpoint Test A .
U1123 Invalid or Missing Data For Odometer Instrument Cluster Go To Pinpoint Test G . U1059 SCP (J1850) Invalid or Missing Data for Transmission/Transaxle/PRNDL PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Instrument Cluster REFER to Section 413-01 . U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Tire Pressure Monitoring System Module REFER to Section 204-04 . You need to take it to the dealer , not a transmission shop. Your vehicle could have a ground issue , could have power issue , could have a control module issue . It needs to be hooked up to the factory scan tool ! It is for sure it has a communication problem on the SCP data bus , do you know what serial data communication is ?
The vehicle has 3 module communication networks:
  • the standard corporate protocol (SCP) communications network
  • the international standards organization (ISO) 9141 communications network
  • the universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network
The diagnostic tool connects to all 3 networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one diagnostic tester to be able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering column and the radio.
The SCP communications network will remain operational even with the severing of one of the bus wires. Communications will also continue if one of the bus wires is shorted to ground or voltage, or if some but not all termination resistors are lost. The SCP communications network allows inter-module communication.
The ISO 9141 communications network does not permit intermodule communication. When the diagnostic tool communicates to modules on the ISO 9141 communication network, the diagnostic tool must request all information, or initiate module commands.
The ISO 9141 communications network will not function if the wire is shorted to ground or battery voltage. Also, if one of the modules on the ISO 9141 communications network loses power or shorts internally, communications to that module will fail.
The UBP communications network will not function if the wire is shorted to ground or voltage. The UBP is different from the ISO communication network in that it allows intermodule communication.

I have 08 ford escape when I try to scan it said no communication


Do you know about communication networks or serial data communications on vehicles , these let the scan tool communicate with the different modules on the vehicle ! Newer vehicles have several, PCM - powertrain control module , Anti-theft module , Air bags , antilock brakes , Body control module or in the case of ford a smart junction box . an some others !
Communications Network Vehicle communication utilizes both International Standards Organization (ISO) 9141 and controller area network (CAN) communications. ISO 9141 is used for diagnostic use only, and CAN is used for many modules to communicate with each other on a common network. CAN in-vehicle networking, is a method for transferring data among distributed electronic modules via a serial data bus. Without serial networking, intermodule communication requires dedicated, point to point wiring resulting in bulky, expensive, complex, and difficult to install wiring harnesses. Applying a serial data network reduces the number of wires combining the signals on a single network. Information is sent to the individual control modules that control each function.
The vehicle has 3 module communication networks:
  • ISO 9141
  • Medium speed (MS) CAN
  • High speed (HS) CAN
All 3 networks are connected to the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one scan tool to be able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering column and the audio unit.
HS-CAN Network Operation
The HS-CAN network communicates using bussed messages. The HS-CAN network uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, this network allows sharing of information between all modules on the network.
The HS-CAN is a high speed communication network used for the following modules:
  • ABS module
  • 4WD control module (if equipped)
  • Instrument cluster
  • PCM
  • MS-CAN Network Operation
    The MS-CAN network communicates using bussed messages. The MS-CAN has an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, this network allows sharing of information between all modules on the network.
    The MS-CAN is a medium speed communication network used for the following modules:
    • Instrument cluster
    • SJB
    HS-CAN Network
  • What type of scan tool are you using ? or are you using a code reader ?

Code p1649 power train data us missing message from abs ecu


As you noted, a P1649 code is basically a communication error. It is generally caused by 2 things, either a short in the CAN bus data wires, there are 2 wires, wrapped around each other,Can high and Can low, or the central terminal resistor, which is located inside the ECM. You can test the wires for resistance or a short fairly easily with a good multimeter, but checking the resistor is more difficult, and requires a breakout box and a good scan tool. Might be a good idea to let a VW dealer or a good shop that specializes in VW to diagnose it and take it from there.

Code p1649 abs light stays on and brake light flashes


code p1649 refers to CAN data bus, ABS-- no signal==causes--ABS control module trouble /s stored , --wiring--matching resistor in ECM

Check with a VW service centre as it may be a problem in the ECM connected to the ABS control module.
