Test 8B - Bus Short To 5 Volts
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see appropriate article in ENGINE PERFORMANCE:
- WIRING DIAGRAMS - 3.3L
- WIRING DIAGRAMS - 3.5L
- After each repair, perform TEST VER-1.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. 6 (Violet/White wire) and No. 26 (Violet/Brown wire). If resistance is less than 5 ohms, repair short between Violet/Brown wire and Violet/White.
- If resistance is more than 5 ohms, check resistance between PCM connector terminals No. 6 (Violet/White wire) and No. 46 (White/Black wire). If resistance is less than 5 ohms, repair short between White/Black wire and Violet/White/ wire. If resistance is more than 5 ohms, replace PCM.
NOTE:
A break in test sequence occurs at this point. No test procedures have been omitted.
