SOURCE: Ford Focus 1.6 LX Auto 2005 code U0001 error - was fixed by diagnostics - now doing it again?

This code is a communication error code. Modern cars have many computer modules that must talk to each other. when there is a problem with one sending or receiving data the main computer recognizes this and goes into what is known as "limp mode" as to not leave you stranded.
Have you had any work done, or made any modifications to the car lately? It could be something as simple as a grounded out pin at the ALDL connector where you plug the scan too in, it could be a bad wire in one of the wire harnesses, or a bad connection at one of the main connectors where the harness attach to the module. I know this is a vague answer, but hopefully it gives you a place to start.

2005 volvo xc90 will not stay running, it is giving a code of U0073 generic control module communication bus"a" off. .we have put in new crank sensor. the maf sensor is not the problem


Do you know what a serial data communication network is ? All the control modules on your vehicle share info on it . It stead of hard wiring all the componets on the vehicle they use control modules and a data network . U codes are problem codes assoicated with these networks . U0073 generic control module communication bus"a"OFF Has nothing to do with engine sensors ! Condition
The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network).
The diagnostic trouble code (DTC) is stored if the control module detects that:
  • The control module does not have contact with the controller area network (CAN).
  • Incorrect value runs longer than 10 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
  • Starting the control module's CAN communication.
Note!The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met. In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the fault if it is intermittent. Substitute value
  • None.
Possible source
  • Open-circuit in terminals.
  • Damaged Parking Assistance Module (PAM).
Fault symptom[s]
  • Parking Assistance System, malfunction
  • Information lamp is on
  • Message in information display

A shorted module will cause the data bus to short and cause no start condition . You best bet , take it to a qualified repair shop . How to Diagnose Controller Area Network CAN

What would cause a code 4354 on a 2016 Freightliner Cascadia?


the code means something but only if the engine make , type and transmission make and type is known
Freightliners run 3 different engine and up to 4 different transmissions and the code will be specific to that combination
take it to a freightliner service center and have it fixed

2005 Nissan Almeira code P1320 Primary Ignition Control, no problem or indication of problem existed and suddenly overnight vehicle would not start, managed to start vehicle after 1 hr struggle removing...


I think I would start with checking fuel pressure. You should have at least 40PSI at the fuel rail. You might have someone help you our and turn on the key while you get under your vehicle and listen for the whirrr of the fuel pump. It should cycle for about 3 seconds when the key is turned to the "ON" position to prime the system to start. If you can not hear the pump run or it does not sound smooth I think you will need to replace it.

My problem is in the gear box (U0103 COMM. SHEFT) the car model 2005 chasis number (1J4GS48KX5C682794) so please what is the problem? Many thanks.


Diagnostic Fault Code (DTC) U0103 is a communications fault.

The Transmission Control Module (TCM) receives information from the Engine, Anti-Lock Brake Systen and the Electronic Gear Shift Control modules over the CAN C bus. (CAN = Cable Area Network)
The CAN C bus is a high speed communications bus that allows real-time control capability between various control modules. Most messages are sent every 20 mSec, this means critical information can be share between multiple modules almost instantaneously. The CAN C bus is a two-wire bus with a CAN (+) and a CAN (-) circuit.
To reduce the potential of radio and other electrical noise interference, the CAN Bus circuit is manufactured using a twisted pair configuration within the wiring harness.
Diagnostic Test Codes (DTCs) with the prefix of "U" are communications faults. The types of DTCs indicate that one or more of the modules within the CAN network is not communicating properly with the rest of the modules.
For this vehicle, DTC P0103 indicates that the Transmission Shift Module is having difficulty communicating on the CAN network.
The network connections as well as power and ground circuits to the Transmission Shift Module must be verified for proper operation. This includes accessing the network with a scan tool that has the capability of two-way communications with all of the modules on the CAN network.
Please note that MOST generic OBD code readers do not have this capability.

Did not pass state inspection (vehicle)


First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.
