Test 8G - Short To 5 Volts

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Using an external ohmmeter, check resistance between Blue BCM connector terminal No. 7, CCD bus positive circuit (Violet/Brown wire), and terminal No. 2, key-in ignition switch input circuit (Light Blue wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Light Blue wires. Perform TEST VER-1.
  2. If resistance is more than 5 ohms, check resistance between Blue BCM connector terminal No. 20, CCD bus negative circuit (White/Black wire), and terminal No. 2, key-in ignition switch input circuit (Light Blue wire). If resistance is less than 5 ohms, repair short between White/Black and Light Blue wires. Perform TEST VER-1.
  3. If resistance is more than 5 ohms, check resistance between Blue BCM connector terminal No. 7, CCD bus positive circuit (Violet/Brown wire), and terminal No. 14, seat belt switch input circuit (Light Green/Red wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Light Green/Red wires. Perform TEST VER-1.
  4. If resistance is more than 5 ohms, check resistance between Blue BCM connector terminal No. 20, CCD bus negative circuit (White/Black wire), and terminal No. 14, seat belt switch input circuit (Light Green/Red wire). If resistance is less than 5 ohms, repair short between White/Black and Light Green/Red wires. Perform TEST VER-1.
  5. If resistance is more than 5 ohms, check resistance between BCM case and ground. If resistance is more than 5 ohms, repair BCM case ground. Perform TEST VER-1. If resistance is less than 5 ohms, check resistance between Blue BCM connector terminal No. 19, signal ground circuit (Black/Light Green wire), and ground.
  6. If resistance is more than 15 ohms, repair open in Black/Light Green wire. Perform TEST VER-1. If resistance is less than 15 ohms, replace BCM. Perform TEST VER-1.
