Opening the unit: high difficulty

  • Ordinary circuit board in a two-part aluminium housing closed with sealant; thermal compound holds the board to the housing.
  • On most versions direct access means freeing the board from both halves of the housing and soldering six or seven small bridges.
  • Tool documentation advises refitting the unit and checking that the engine starts after opening, before any further work.
  • Normally read and written through the diagnostic socket; opening is only for recovery, cloning or a full backup.

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.
