The vehicle connector shall be red coloured.
The vehicle connector and the external test equipment connector shall have latching features to ensure that the external test equipment connector will remain mated when properly connected.The latching feature shall be designed to provide a positive feel when the external test equipment connector is fully seated.
The vehicle connector shall have the latch mechanism that can be released when disconnect latched connectors.
Accelerated environmental testing shall be conducted for the vehicle connector when not mated to the external test equipment connector. However, the suitable cover according to 5.7.4 e) shall be attached on the vehicle connector. Perform each environmental exposure, a) to d), as follows, with separate sample groups. After exposure, the vehicle connector shall be mated to the original external test equipment connector for the performance tests given in 5.7.3 and 5.7.4.
If a two-wire or one-wire ISO 9141-2 or ISO 14230-4 interface is used in a vehicle to supply OBD required communication services, then Contact 6 of the vehicle connector shall be the K line of the interface.
However, if neither interface is used for that purpose, then assignment of the contact is left at the discretion of the vehicle manufacturer, provided the assignment does not interfere with the operation of, nor cause damage to, tools conforming to ISO 15031-4.See ISO 15031-3:2004, 6.3.6.
The vehicle manufacturer should provide circuit protection in the event that the contacts of the vehicle connector are shorted together. This protection is limited to the ranges of voltages present at the vehicle connector before the external test equipment connector is mated to it. See ISO 15031-3:2004, 6.4.
Contact 3 of the external test equipment connector is designated ground. This contact shall be used by the ISO 15031-4 external test equipment as the signal ground reference for vehicle communication transceivers. This contact may be used by the external test equipment as a power ground.
Contact 4 of the external test equipment connector is designated as permanent positive voltage or switched vehicle battery voltage (Ignition on/off) and is available to supply operating power and a reference voltage to the external test equipment.ISO 19689 pdf free.
