Where can I find the CAN bus on a vehicle?

Table of contents
No headers

The use of CAN Bus in road vehicles to date has been mostly for internal ECU communication and therefore it is common for vehicles not to have CAN available on a convenient connector. In cases such as this, it may be necessary to tap directly into vehicle CAN wiring to pick up signals. Typical places to pick up CAN include the ABS system (look for a pair of twisted wires, but ignore the four wheel speed wires) or on the back of the dashboard (look for a pair of twisted wires).

If the vehicle does have CAN Bus on the OBD connector, it will normally be on Pins 6 and 14 as indicated below.
