Not configured This sub type is used by the server to indicate the need to enter program the sub system option content or the vehicle option content. In accordance with Adobe’s licensing policy, this file may be printed or viewed but shall not be edited unless the typefaces which are embedded are licensed to and installed on the computer performing the editing.
Missing message This sub type is used for failures where one or more expected message s is not received, e. A ConfirmedDTC does not always indicate that the malfunction is necessarily present at the time of the request. Incorrect assembly This sub type is used for failures where sio server has detected that the component has been incorrectly installed e. System Programming Failures This sub type is used for System Programming Failures that cannot be assigned to a specific sub type.
Figure 6 — A-PDU timing diagram confirmed services — functional target address 4? DL determines the number of valid message data bytes of a single frame message.
Circuit open This sub type is used for failures, where the server determines an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output, etc. The maximum length is limited by the maximum length of a segmented message to bytes. Actuator stuck closed This sub type is used for failures where the server does not detect any motion upon commanding the operation of a motor, solenoid, relay, isoo.
A further service request will be rejected. The Server has understood the service request, but it cannot execute the service at this time and will not start the service at any time later, e. Signal erratic This sub type is used for failures where the signal is momentarily implausible not long enough for “signal invalid” or discontinuous. Subscription pricing is determined by: Server 11992-44 error handling, e.
This parameter is only present if DTC information is available to be reported.

If the test runs and passes or fails then the bit shall be set and latched to ‘0’ until a new monitoring cycle is started. The maximum length allowed is bytes.
Reception of an unexpected protocol data unit. Recommended test equipment display text: Table 35 specifies the sender and receiver reaction for the error conditions. Actuator stuck open Lso sub type is used for failures where the server does not detect any motion upon commanding the operation of a motor, solenoid, relay, etc.

Details of the software products used to create this PDF file can be found in the General Info ixo to the file; the PDF-creation parameters were optimized for printing.
The diagnostic services specification includes tables which list diagnostic services and respective service primitive parameters. Delay time between server indication and first response. Retrieved from ” https: The lso structure is similar to SAE J These functions shall be used by application layer entities requesting the respective network layer service via the layers in between.

ISO All 1992-4 reserved. For undated references, the latest edition of the referenced document including izo amendments applies. For the communication between road vehicles and their towed vehicles the restrictions described in this clause shall apply in addition. 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.
Circuit current below threshold This sub type is used for failures, where the server measures current flow below a specified range.
The server shall then send no response code and change to the AS state. This parameter is only present if the data record 119924 of more than one data byte. Its full title is “Road vehicles — Interchange of digital information on electrical connections between towing and towed vehicles”.
