SAE J1939

Diagnostic protocols for heavy-duty commercial vehicles

SAE J1939 describes the CAN communication for commercial vehicles and the principles for the exchange of information between ECUs as well as diagnostic data. The aim is to define standard communication mechanisms regardless of the OEM, engine/transmission manufacturer and test system manufacturer.

Today, SAE J1939 is used throughout for heavy-duty commercial vehicles such as trucks, busses and construction equipment - particularly outside Europe. For agricultural machinery ISOBUS is mandatory which is based on J1939.

Softing Experience

The standard was first implemented at Softing as early as 1995 - so Softing really can speak of long years of experience! Since then, a large number of projects have been carried out based on specific customer requirements, both in terms of the tester and in the ECU. SAE J1939 is supported by our products DTS Monaco (engineering tester), Softing TDX (service tester) and by the VCIs of the HS and VIN|ING family. Especially the support of UDS (ISO 22900) in J1939 networks and the implementation at ODX data are current issues bothering the market. The solutions from Softing are ready for this combination.

visitor_idACCOUNTID	The visitor cookie includes a unique visitor ID and the unique identifier for your account. For example, the cookie name visitor_id12345 stores the visitor ID 1010101010. The account identifier, 12345, makes sure that the visitor is tracked on the correct Pardot account. The visitor value is the visitor_id in your Pardot account. This cookie is set for visitors by the Pardot tracking code.	10 years	HTML	Pardot
pi_opt_inACCOUNTID	If Tracking Opt-in preferences is enabled, the pi_opt_in cookie is set with a true or false value when the visitor opts in or out of tracking. If a visitor opts in, the value is set to true, and the visitor is cookied and tracked. If the visitor opts out or ignores the opt-in banner, the opt-in cookie value is set to false. The visitor cookie is disabled, and the visitor is not tracked.	10 years	HTML	Pardot
visitor_idACCOUNTID-hash	The visitor hash cookie contains the account ID and stores a unique hash. For example, the cookie name visitor_id12345-hash stores the hash “855c3697d9979e78ac404c4ba2c66533”, and the account ID is 12345. This cookie is a security measure to make sure that a malicious user can’t fake a visitor from Pardot and access corresponding prospect information.	10 years	HTML	Pardot
lpvACCOUNTID	This LPV cookie is set to keep Pardot from tracking multiple page views on a single asset over a 30-minute session. For example, if a visitor reloads a landing page several times over a 30-minute period, this cookie keeps each reload from being tracked as a page view.	30 minutes	HTML	Pardot
pardot	A session cookie named pardot is set in your browser while you’re logged in to Pardot as a user or when a visitor accesses a form, landing page, or page with Pardot tracking code. The cookie denotes an active session and isn’t used for tracking.	10 years	HTML	Pardot
