Question

Technician A says Chrysler OBD-I (1981—1995) vehicles were equipped with a BUS system called Serial Communications Interface (SCI). Technician B says The Chrysler Programmable Controller Interface (PCI) is a three-wire communication protocol that connects at the OBD-II DLC at terminal 2. Which technician is correct?

Answer 1

Technician A is correct. Chrysler OBD-I vehicles were equipped with a BUS system called Serial Communications Interface (SCI). Technician B is incorrect, as the Chrysler Programmable Controller Interface (PCI) is not related to OBD-II or terminal 2 of the DLC.

Step-by-step explanation:

Technician A is correct. Chrysler OBD-I vehicles between 1981 and 1995 were indeed equipped with a BUS system called Serial Communications Interface (SCI). The SCI provided a means of communication between various modules in the vehicle, allowing them to exchange information and perform functions.

Technician B is incorrect. The Chrysler Programmable Controller Interface (PCI) is not a three-wire communication protocol that connects at the OBD-II DLC at terminal 2. The PCI is actually a different communication protocol used in some Chrysler vehicles, but it is not related to OBD-II or terminal 2 of the DLC.
