    I get the "error code NC315-1W" when I test the wireless router. The ethernet modem works fine and tests fine. I'm assuming the router if fried. Could it be anything else?

As for the error code, it's fairly generic, but indicates that your network card is having trouble communicating with the network. The good news is this is most likely not a hardware issue, but would most likely be caused by either a bad driver.

It is also possible that a firewall product, such as McAfee provides with it's antivirus software could be interfering with your network card's communications.

After you've tried replacing the driver, disable your antivirus software for a minute and test you connection to another computer or the internet (only a name brand site you absolutely trust) if the problem goes away, then try changing your firewall settings on that program or try a different program altogether.

That should cover most of the problem.

On my 05 Ford mustang v6, my fan only comes on when i turn my AC on and makes a funny noise when I turn the AC on, diagnostic test gave me a code, u1900, what does this mean and how do I fix it?


Where did you pull this code from ? What type scan tool did you use ,or was it a code reader ? Do you know about data communication networks on modern cars ? A U codes indicate a communication problem on the data network .
U1900 CAN Communication Bus Fault-Receive Error Audio Control Module REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error ABS Module REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error Instrument Cluster REFER to Section 418-00 . U1900 CAN Communication Bus Fault-Receive Error SJB REFER to Section 418-00 . The thing that would make this easier to diagnose would be to have a factory scan tool or a professional grade . Need to know what modules can communicate with scan tool .Honestly ,Don't think you can fix this . Dealer or ASE certified repair shop .Do you know what C.A.N. - controller area network is ? The vehicle has 3 module communications networks:
  • high speed controller area network (CAN)
  • medium speed CAN
  • international standards organization (ISO) 9141 communications network
The diagnostic tool connects to the communications networks through the data link connector (DLC). The DLC allows a diagnostic tool access to diagnose and test the vehicle systems of any module on the communications networks.
All 3 communications networks are connected to the DLC. This makes diagnosis and testing of these systems easier by allowing one diagnostic tool to be able to diagnose and control any module on the 3 communications networks from one common connector. The DLC can be found under the instrument panel between the steering column and the driver door. Which module doesn't communicate with scan tool ?

Network Diagnostic Procedures


Network Diagnostic
To check if the network card is OK go into the Control Panel - System - Hardware - Device Manager and click on Network adapters. Right Click on your network card then Properties see if it is enabled and working properly.
If not download and install the latest version of the network card driver.
If this is OK then you need to test if the network card has been issued with an IP address from the router/modem.
Click Start - Run and then type cmd and press return (to open a DOS command box)
Then type ipconfig and press Return
If you then get 0.0.0.0 for an IP Address then you have an IP address problem.
Next you need to do a Loop back test to determine if the network card is OK
In the DOS command box type ping 127.0.0.1 and if you get a reply from 127.0.0.1 then the network is OK.
If the reply is “Ping request could not be found” then problem is with the router/modem.

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.

Printer will not communicate with the computer


1. Walk over to the printer and print a test page directly. The procedure for printing a test page will vary from model to model, so you may need to consult the user guide that came with your printer. For most network printers, you can print a test page by navigating the "Information" menu on the control panel and choosing "Print Configuration" from the menu. For many desktop printers, you can print a test page by holding the power button until the page begins to print. If you can print a test page from the printer, but not from the computer, you know there is a communication problem between the printer and the PC.


2. Remove the printer cable from the back of your printer and the back of your computer. After the cable has been removed, carefully put the cable back into place, making sure that the printer cable is tight. If your printer uses a parallel cable, be sure that it is fully seated on the back of the printer and on the computer. If you are using a USB cable for your printer, be sure that the tab is fully seated in the computer, and that the square end of the cable is firmly connected to the printer.


3. Power down the printer, the restart your computer. Click on the "Start" button and choose "Control Panel" from the menu. Double-click the "Printers and Faxes" icon, locate your printer, right-click on it and choose "Properties" from the menu. Click on the "Print Test Page" button to send a test page to your printer.


4. Look at the network card on your network printer to see if there is good communication between the printer and the network. You should see a flashing green light on the network card. If there is no light--or if the light is amber or red--the communication is not happening. To test the network communication, remove the network cable from both the network cable and the network port on the wall, then reseat the cable and check the communication again. If the problem remains, you will need to remove and replace the printer's network card.

Hi, I am having trouble connecting my new laptop to cable as I don't have a wireless network as yet. The error says there is no IP recognised when I run a diagnostic test. Cheers Pete


Go to Control Panel - System - Hardware tab - Device Manager and check the network adapter is OK.
If there is a yellow ? against the LAN driver and the wireless card then the device drivers for these device have to be installed.
After installation then you will n\be able to connect a LAN cable from your computer to the wireless router and configure the wireless settings.

Power management related query


Some system have a BIOS settings like these. There are 2 options affecting the NIC. LAN/WLAN switching and LAN power save. Are both LAN power save and LAN/WLAN switching enabled?

On my laptop, it does the same thing as your computer when its on battery (HP laptop) except when there is an ethernet cable plugged in or loopback. I made a little loopback plug to keep the port active even when it is unplugged.
