Opening the unit: high difficulty
- Normally read and written through the connector or OBD, with the housing closed.
- Locked units (from about mid-2020) can need a boot unlock: the housing is opened and a small part on the board is unsoldered and refitted.
- Some versions must be opened on both sides; the board is bonded to the housing and can break when it is lifted.
- A damaged part or pad can leave the unit without communication.
Advice: Keep it closed whenever the job can be done without opening it. If work inside the unit is needed, leave it to someone who opens this unit regularly.
General information: units with the same name can differ. Follow your tool's connection guide.
