When cloning OE sensors, it’s important to pay attention to the ID type. If the sensor ID is manually entered into the programming tool, then it’s necessary to match the format.

Hexadecimal is a base-16 system, so each digit can be a number (0-9) or a letter (A-F). Using such a system allows bigger numbers to be represented using a fewer number of characters.

Decimal is a base-10 system, so each digit can only be a number. It takes more characters to represent sensor IDs using the decimal format compared to hex.

Example: 12345678 (decimal) is BC614E in hex.

Technicians can adjust the TPMS tool’s ID format in the settings menu, which eliminates confusion because the tool will always show the IDs in the select format when reading sensors, until the setting is changed.

If the original sensor is still functioning, it’s recommended to use the tool’s Copy option because it obtains the exact ID for cloning by reading the OE sensor. If the OEM sensor is intact but not working, then the Manual ID option can be used.
