Test 7B - Short To Battery
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
section at the end of this article.
CAUTION:
Always turn ignition switch to OFF position before disconnecting or connecting any module connector.
- Using an external ohmmeter, check resistance between Powertrain Control Module (PCM) connector terminals No. 26, CCD BUS positive circuit (Violet/Brown wire) and PCM terminal No. 7, 8-volt supply circuit (Orange wire). If resistance is less than 5 ohms, repair short between CCD BUS positive circuit and 8-volt supply circuit. Perform TEST VER-1.
- If resistance is more than 5 ohms, check resistance between PCM connector terminals No. 46, CCD BUS negative circuit (White/Black wire), and PCM terminal No. 7, 8-volt supply circuit (Orange wire).
- If resistance is less than 5 ohms, repair short between CCD BUS negative circuit and 8-volt supply circuit. Perform TEST VER-1. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-1.
