  1. Using an external ohmmeter, check resistance between PCM connector terminal No. 26, CCD bus positive circuit (Violet/Brown wire), and terminal No. 6, 5-volt supply circuit (Violet/White wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Violet/White wires. Perform TEST VER-1.
  2. If resistance is more than 5 ohms, check resistance between PCM connector terminal No. 46, CCD bus negative circuit (White/Black wire), and terminal No. 6, 5-volt supply circuit (Violet/White wire).
  3. If resistance is less than 5 ohms, repair short between White/Black and Violet/White wires. Perform TEST VER-1. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-1.
