• How do I test a car relay with the AERMOTOR Relay Tester?

  Clamp the red clip to the positive pole of a 12V-24V car battery and the black clip to the negative. Set the switch to 4PIN or 5PIN depending on your relay, plug the relay into the slot, and press the test button. A flashing green light indicates the relay is working properly, while a red light indicates a fault.

• Where do I plug in the AERMOTOR V410 OBD2 Scanner?

  The OBD2 port is typically located underneath your vehicle's dashboard on the driver's side, often positioned just above the accelerator or brake pedals.

• Can the AERMOTOR P100 Plus measure voltage and resistance?

  Yes, the AERMOTOR P100 Plus Circuit Probe acts as a comprehensive multimeter, capable of accurately measuring and displaying standard voltage, frequency, and resistance values on connected vehicle circuits.

• How do I use the AERMOTOR TPMS Relearn Tool?

  First, place your vehicle into TPMS learning mode (this commonly involves a sequence of key turns or dashboard settings until the horn honks twice). Starting with the front-left tire, point the tool's antenna at the tire sidewall near the valve stem and press the button. Once the car horn chirps, the sensor has been read. Proceed in the required order: front left, front right, rear right, rear left.
