What is J1850 PWM protocol?

J1850-41.6 – Ford 41.6 standard refers to Ford’s communication protocol. This protocol has been used by Ford since 1996. With Ford’s protocol, each bit of information is 24 us long and has variable voltage pulse widths to represent a logic 0 or 1. This is referred to as Pulse Width Modulated (PWM) system.

How do you use OBD?

Plug the standard OBD2 connector into the vehicle’s port located under the driver’s side of the dashboard. Turn on the car to power the scan tool or code reader. If necessary, enter any vehicle-specific information requested. Many tools will ask for the Vehicle Identification Number (VIN).
