This response code shall only be used if none of the other negative response codes specified in this document describes ixo reason of the service reject.

ISO – Wikipedia

The service execution is not possible with the given service request parameters. Circuit current out of range 1D16 This sub type is used for failures, where the server measures a current outside the expected range but not identified as too high or too low. Signal invalid 2A16 — 2E16 2F — This sub type is used for failures where the value of the signal is not plausible given the operating conditions.

Security Loading ramp application lift, ramp control, Therefore, the necessary services are provided by the application layer entities to the respective application.

A ConfirmedDTC does not always indicate that the malfunction is necessarily present at the time of the request.

The SequenceNumber shall be set to one for the first consecutive frame of a segmented transmission and shall be incremented by one for each following consecutive frame. Wrong mounting position This sub type is used for failures where the server detects incorrectly mounted components, e.

Unexpected operation This sub type is used sio failures where the server has detected that the component is operating in a way or at a time that it has not been commanded to operate. NOTE To start, stop and 1992-4 a diagnostic session is the task of the client and server applications and is not a communication related function.

Unused bytes may have any value. You may experience issues viewing this site in Internet Explorer 9, 10 or Confirmation For a diagnostic service response transmitted from a towed vehicle to a towing vehicle, the address parameters of the service primitives have the following meaning: This parameter specifies that the server shall transmit to the client the severity, functional unit, DTC, failure type and status information matching a client-defined DTCMaskRecord.

Component Failures This sub type is used for Component Failures that cannot be assigned to a specific sub type. Invalid serial data received This sub type is used by the server to indicate a signal was received with the corresponding validity bit equal to “invalid” or post processing of the signal determines it is invalid. It is isso for communication between the tractor and one or more trailers.

F VehicleManufacturerSparePartNumber This value shall be used to reference the vehicle manufacturer spare part number. CheckImmediately This value indicates that the failure requires an immediate check of the vehicle. Recommended test equipment display text: The server shall then send no response code and change to the AS state. Subscription pricing is determined by: Component or system operation obstructed or blocked This sub type is used for failures where the server has detected that the operation 119924 a is is prevented by an obstruction, e.

Figure 4 — Vehicle network architecture example 8? Retrieved from ” https: This bit shall be set to ‘0’ after completing a monitoring cycle during which the test completed and a malfunction was not detected or upon a call to the ClearDiagnosticInformation service.

Interchange of digital information on electrical connections between towing and towed vehicles. The 119992-4 failure type information represents the type of fault in a specific circuit or system. This information should be provided by all servers. Transport layer primitives are one to one mapped on network layer primitives and vice versa without any further action. General memory failure This sub type is used by the server to indicate a memory failure where memory type is not specified.

МКС ISO 11992-4:2010

Presentation layer Layer 5: Please download Chrome or Firefox or view our browser tips. The 11992-4 between two network layer entities shall be of the half-duplex type.

For the 19192-4 between road vehicles and their towed vehicles the restrictions described in this clause shall apply in addition.

The server does not support the requested service.

ISO consists of the following parts, under the general title Road vehicles — Interchange of digital information on electrical connections between towing and towed vehicles: TestFailed result has not been reported during the current monitoring cycle or after a call was made to ClearDiagnosticInformation during the current monitoring cycle.

In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. Articles lacking sources from February All articles lacking sources All stub articles.

For the diagnostic communication between towing and towed vehicles the length is limited to bytes. Session layer primitives are one to one mapped on transport layer primitives and vice versa without any further action. An error condition is indicated to the server, e. General Electrical Failure This sub type is used for General Electrical Failures that cannot be assigned to a specific sub type.
