Opening the unit: medium difficulty

  • Ordinary circuit board in a sealed aluminium housing; one cover gives access.
  • One boot contact sits under the edge of the processor and is reached with a fine needle on a support arm.
  • Many versions can be written through the diagnostic socket; when no virtual read exists, the first read is done in boot mode.

Advice: Check first whether the job can be done without opening it. If you open it, cut the sealant, never lever on the board, and reseal it afterwards.

General information: units with the same name can differ. Follow your tool's connection guide.
