Test 7B - Short To Battery

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. Disconnect camshaft position sensor connector. Camshaft position sensor connector is located above timing cover, next to coolant temperature sensor. Using an external ohmmeter, check resistance between PCM connector terminal No. 26, CCD bus positive circuit (Violet/Brown wire), and camshaft position sensor connector 8-volt supply circuit (Orange wire).
  2. If resistance is less than 5 ohms, repair short between Violet/Brown and Orange wires. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, check resistance between PCM connector terminal No. 46, CCD bus negative circuit (White/Black wire), and camshaft position sensor connector 8-volt supply circuit (Orange wire).
  3. If resistance is less than 5 ohms, repair short between White/Black and Orange wires. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace PCM. Perform VERIFICATION PROCEDURE VER-1.
