Gear Selector Lever Switch
Check the gear selector lever switch by means of the universal adapter with the control unit connected and ignition switched on. Measure between Pin 1 (-) and the specified pins. "0" corresponds to approximately zero volt, "1" corresponds to approximately 12 volts. If a voltage is not measured at any position, check voltage supply of the selector lever switch. If activation is defective, remove and check selector lever switch. See GEAR SELECTOR LEVER SWITCH CHECK (3-SERIES E36)
