Notice: To ensure accurate results, please select the correct battery type, standard, and CCA or AH value, and confirm the in vehicle/out of vehicle condition and temperature (above/below 0°F) prompts correctly.
  • OBD2 SCANNER: The TopDiag T400 car scanner diagnostic tool can easily determine the cause of the check engine light coming on, quickly read and clear fault codes, read live data & hard memory data, view freeze frame, I/M monitor readiness and collect vehicle information.

Whether it's fixing your lights on the go or ensuring your road trip stays illuminated through out the night. WARNING: Ensure relays DC voltage is matched with vehicle battery DC voltage.
