Test 8B - Short To 5 Volts
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
in this article. For wiring diagram, see WIRING DIAGRAMS
in this article.
CAUTION:
Always turn ignition switch to OFF position prior to 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 No. 6, 5-volt supply circuit (Violet/White wire). If resistance is less than 5 ohms, repair Violet/Brown wire shorted to Violet/White wire. 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 No. 6, 5-volt supply circuit (Violet/White wire).
- If resistance is less than 5 ohms, repair White/Black shorted to Violet/White wire. Perform TEST VER-1. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-1.
NOTE:
Test procedures skip from TEST 8B to TEST 8E. No test procedures have been omitted.
