What does KWP2000 mean on a code reader?

KWP2000 (Keyword Protocol 2000) is not a trouble code but rather is the name given to a type of communications protocol that is used for on-board vehicle diagnostics systems. Auto diagnostic tools and programmers use Keyword Protocol 2000 to read and transfer data to your vehicle’s electronic control unit, or ECU.

What is the code ISO 9141 2?

It specifies the requirements for setting up the interchange of digital information between on-board emission-related Electronic Control Units (ECUs) of road vehicles and the SAE OBD II scan tool as specified in SAE J1978. This part of ISO 9141 is limited to vehicles with nominal 12 V supply voltage.

How do you use a CAN OBD2 code reader?

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).

CAN obd2 be high?

These wires are called CAN high and CAN low. When the CAN bus is in idle mode, both of these lines carry 2.5V but when data bits are being transmitted, the CAN high line goes to 3.75V and the CAN low drops to 1.25V….All About CAN Bus.
