NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION in appropriate TESTS W/CODES
article below. For appropriate wiring diagram, see WIRING DIAGRAMS
section. Perform TEST VER-1 after each repair.
- TESTS W/CODES - 3.9L
- TESTS W/CODES - 5.2L GASOLINE
- TESTS W/CODES - 5.9L GASOLINECAUTION: 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 CCD BUS positive circuit 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, and No. 6, 5-volt supply circuit (Violet/White wire).
- If resistance is less than 5 ohms, repair CCD BUS negative circuit 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.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
