SOURCE: Audi fault code J386 (2002)

There's a TSB on that problem. It involves broken wires in the A and B pillar from the central convenience module to the rest of the car. Ask your VW dealership or what not for a more specific answer.

What is the most likely cause an error code u1900 in a 2008 ford explorer xlt 4wd


Do you know what a serial data network is ? With all the computers car makers put on thier cars these day's they need a communication network for them to talk ,share info. on etc. U codes are codes for the network . A module could be down ,could be a wiring problem . A shorted module or bus wire can bring down the whole vehicle. Could cause the vehicle not to start ,systems not to function . How did you pull this code ,with what scan tool or code reader ? Did it come from the PCM - engine computer ? Need a up scale professional scan tool to check all module's on the vehicle , need to pin point the module that is causing the problem .

016 CAN Communications

SECTION 418-00: Module Communications Network 2007 Explorer/Mountaineer/Explorer Sport Trac Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 08/02/2006 Communications Network Vehicle communication utilizes both medium and high speed controller area network (CAN) communications. 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 2 module communication networks:
  • Medium speed (MS) CAN
  • High speed (HS) CAN
Both 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 both networks from one connector. The DLC can be found under the instrument panel between the steering column and the audio unit.

Yes Occupant classification sensor (OCS) module HS-CAN No Parking aid module (PAM) (if equipped) MS-CAN No Powertrain control module (PCM) HS-CAN Yes Power running board (PRB) module (if equipped) MS-CAN No Restraints control module (RCM) HS-CAN No Satellite digital audio radio system (SDARS) (if equipped) MS-CAN No Smart junction box (SJB) MS-CAN Yes Transmission control module (TCM) (if equipped) HS-CAN No
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:
  • SJB
  • Audio unit
  • Instrument cluster
  • DSM (if equipped)
  • DVD player (if equipped)
  • EATC module (if equipped)
  • Parking aid module (if equipped)
  • Satellite audio receiver (if equipped)
  • Power running board module (if equipped)
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:
  • PCM
  • TCM (if equipped)
  • RCM
  • ABS module
  • Instrument cluster
  • Occupant classification sensor module
  • 4WD control module (if equipped)
Network Termination
The CAN network uses a network termination circuit to improve communication reliability. The network termination of the CAN bus takes place inside the termination modules by termination resistors. Termination modules are located at either end of the bus network. As network messages are broadcast in the form of voltage signals, the network voltage signals are stabilized by the termination resistors. Each termination module has a 120 ohm resistor across the positive and negative bus connection in the termination module. With 2 termination modules on each network, and the 120 ohm resistors located in a parallel circuit configuration, the total network impedance, or total resistance is 60 ohms.
Network termination improves bus message reliability by:
  • stabilizing bus voltage.
  • eliminating electrical interference.
Gateway Module
The instrument cluster is the gateway module, translating HS-CAN to MS-CAN and vice versa. This information allows a message to be distributed throughout both networks. The instrument cluster is the only module on this vehicle that has this ability.

No bus 5


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Transmision fault on 5 sieries


ello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

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.

Windows dont work on my s320 benz


have you checked fuse's under rear seat? if there ok try disconnecting battery for 1 minute then reconnect and try(make sure you have the radio code before you do it) if still no good check wiring in sleave were it enters the front drivers door,broken cables there are a common fault,if these fail, remove door cards and disconnect control units in doors, drivers side first, this will reset a can bus fault or a regulator sensing fault.also if your control switches are 2 position ie when you press them gently you should feel a click then another click as you press more firmly,try pressing up and down on the first click only, this may also reset an auto up can bus fault
