NOTE—
• Common MINI acronyms are explained in 600 Electrical System—General.
• Airbags systems, formerly known by the acronym SRS (sup
plemental restraint system), are currently referred to by the
BMW acronym MRS (multiple restraint system).
• Every attempt has been made in this repair manual to stan
dardize component names. However, in some cases, the
same component may appear with different names. Regard
less of the component name, the alphanumeric component
designation used on the wiring diagrams is consistentthroughout.
