  1. Turn ignition on and place transmission in Neutral (inhibitor switch on). Check for 12 volts across terminals "A" and "B" at function test connector. See Figure or Figure.
  2. If voltage is not present or if reading is low, check for faulty or unplugged connectors, BCDD solenoid, or inhibitor switch. Repair or replace as necessary.
  3. Place transmission in any gear (inhibitor switch off) and check resistance between terminal "A" and "B" at function test connector. Reading should be less than 32 ohms (15-28 ohms on 280Z and 810 models). If reading is incorrect, check for faulty connector, BCDD solenoid, or inhibitor switch. Repair or replace as necessary.
