Test 8C - Short To 5 Volts

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Using an external ohmmeter, check resistance between BCM Bone connector terminal No. 8, CCD bus positive circuit (Violet/Brown wire), and BCM Gray connector terminal No. 13, evaporator temperature sensor sense circuit (Light Green/Black wire).
  2. If resistance is less than 5 ohms, repair short between Violet/Brown and Light Green/Black wires. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 7, CCD bus negative circuit (White/Black wire), and BCM Gray connector terminal No. 13, evaporator temperature sensor sense circuit (Light Green/Black wire).
  3. If resistance is less than 5 ohms, repair short between White/Black and Light Green/Black wires. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 8, CCD bus positive circuit (Violet/Brown wire), and BCM Gray connector terminal No. 5, 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 VERIFICATION PROCEDURE VER-1.
  4. If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 7, CCD bus negative circuit (White/Black wire), and BCM Gray connector terminal No. 5, 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 VERIFICATION PROCEDURE VER-1.
  5. Check resistance between BCM Bone connector terminal No. 8, CCD bus positive circuit (Violet/Brown wire), and terminal No. 20, 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 VERIFICATION PROCEDURE VER-1.
  6. If resistance is more than 5 ohms, check resistance between BCM Bone connector terminals No. 7, CCD bus negative circuit (White/Black wire), and terminal No. 20, key-in ignition switch input circuit (Light Blue wire).
  7. If resistance is less than 5 ohms, repair short between White/Black and Light Blue wires. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace BCM. Perform VERIFICATION PROCEDURE VER-1.
