CAUTION:
On vehicles with EML (Electronic Power Control) always check the safety path. Connect test adapter (12 7 013) to test adapter (12 7 011). Connect BMW service tester (to measure engine speed). Regulate test adapter (12 7 010/011) in center position. Shift car to neutral and start engine. Govern idle speed to approximately 2000 rpm with the knurled knob on the test adapter. Depress footbrake immediately. Engine speed must fall to idle speed immediately. On vehicles with manual transmission, repeat the test with the clutch pedal. If engine speed drops immediately, the safety path is okay.
CAUTION:
On vehicles with an electronic brake light switch (identifiable by cooling ribs), the lines must be secured with a cable connector.
