MoDiC (Mobile Diagnostic Computer) refers to earlier portable BMW diagnostic equipment. It belongs to the period before the later GT1 and ISTA workshop systems; surviving units and references include MoDiC I, II and III. Treat each generation, installed software and cable set as a separate identification question.
What it did
BMW training material identifies MoDiC alongside DISplus as equipment that could display BMW-specific fault information, including additional fault status and environmental information where provided by the controller. A generic OBD fault reader does not necessarily display the same manufacturer-specific context.
Working with historic equipment
Actual coverage depends on the tester generation, software medium and version, vehicle and adapter. Do not infer that every MoDiC handles every older BMW or that a matching plug proves diagnostic compatibility. The separate yellow head is associated with the later GT1/DISplus setup, not a synonym for the MoDiC itself.
An independent illustrated history includes photographs of MoDiC equipment. Compare DIS software and GT1.
