How many pins does a data link connector have?
The DLC or Data Link Connector is an OBD II, 16 pin, standard connector used in all automobiles manufactured since 1996.
How many terminals are in an OBD-II data Link connector DLC )?
The diagnostic link connector (DLC) on OBD II equipped vehicles is a standardized 16 pin diagnostic connector used to interface an OBD II compliant scan tool with the PCM allowing access to on-board diagnostics and live data streams.
What are the pins on a data link?
Some pins function is standard and required by all manufacturers, while other pins are left to the individual manufacturer’s discretion. For instance, the CAN network’s resistance can be checked with the key off through pins 6 and 14. Today’s vehicles have many onboard computer modules dedicated to different tasks throughout the vehicle.
How many pins does an OBD II connector have?
The connector may have other pins populated that are unimportant. The OBD II connector has 16 pin locations which are numbered as shown below. Vehicle OBD II Connector (front view) CAN Protocol Pins. If pins 5, 6, 14 and 16 are populated, the vehicle supports CAN.
Why are there different types of data link connectors?
Also, prior to 1996, there was no standardization for these connectors, and each manufacturer had its own shape with a unique pin arrangement. After 1996, many manufacturers retained their proprietary connectors in addition to the OBD-II interface, because OBD-II ports are only required to transmit emission -related codes and data.
Why are pin connections important in a RS232 system?
The correct connection of the various pins used for an RS232 data link are key to the operation of the system. Knowing the RS232 pinouts, or pin connections, and being able to make the required links enables the handshaking to operate correctly and the data to flow smoothly.
What do pins 5, 6, 14 and 16 support?
If pins 5, 6, 14 and 16 are populated, the vehicle supports CAN. If pins 5, 7, 16 and, optionally, 15 are populated, the vehicle supports ISO or KWP. If pins 2, 5 and 16 are populated, the vehicle supports VPW. If pins 2, 5, 10 and 16 are populated, the vehicle supports PWM.
What are the colors of a 32 pin PCM connector?
C1 (Blue) PCM 32 Pin Connector Pin Wire Color Description 1 — Empty 2 — Empty 3 Brown w/ White stripe 1X CMP Signal 4 Pink Ignition Feed
The connector may have other pins populated that are unimportant. The OBD II connector has 16 pin locations which are numbered as shown below. Vehicle OBD II Connector (front view) CAN Protocol Pins. If pins 5, 6, 14 and 16 are populated, the vehicle supports CAN.
What kind of pin connections can be made with RS232?
The RS232 (EIA-232-A) specification provides a full set of details for a wide variety of connections that can be used with RS232. While many of them are not normally known, they may be used in some circumstances and therefore the details are provided here for reference.
