Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
PT CAN Terminal Resistors
The PT CAN uses two terminal resistors to establish the correct inductive and capacitive impedance in the communication lines. Two 120 Ohm resistors are located in the wire harness (no longer in the control units as on previous systems). The resistors are located:
- Ahead of the right front wheel. (Behind bumper)
- Below the rear seat.
The resistance is measured by connecting the appropriate adapter to any of the modules on the PT-CAN and measuring resistance between CAN-H and CAN-L.
The measured resistance should be close to 60 Ohms.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
