Test 11D - No Termination

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagrams, see WIRING DIAGRAMS - 3.0L article in ENGINE PERFORMANCE. After each repair, perform TEST VER-1.

CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.

Turn ignition off, and disconnect scan tool. Disconnect Body Control Module (BCM). BCM is located behind right kick panel.
Using an external ohmmeter, check resistance between BCM terminals No. 7 and 20. See Fig 1. If resistance is not 100-140 ohms, replace BCM.

Fig 1: Identifying BCM Terminals
If resistance is 100-140 ohms, check resistance of Violet/Brown wire between BCM Black connector terminal No. 7 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open Violet/Brown wire.
If resistance is less than 5 ohms, check resistance of White/Black wire between BCM Black connector terminal No. 20 and DLC terminal No. 3. If resistance is more than 5 ohms, repair open White/Black wire.
If resistance is less than 5 ohms, disconnect Powertrain Control Module (PCM). PCM is located between DLC and battery, on fenderwell. Check resistance between PCM terminals No. 26 and No. 46. If resistance is not 100-140 ohms, replace PCM.
If resistance is 100-140 ohms, check resistance of Violet/Brown wire between PCM connector terminal No. 26 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open Violet/Brown wire.
If resistance is less than 5 ohms, check resistance of White/Black wire between PCM connector terminal No. 46 and DLC terminal No. 3. If resistance is more than 5 ohms, repair open White/Black wire. If resistance is less than 5 ohms, replace scan tool cable or cartridge as necessary.

NOTE: A break in test sequence occurs at this point. No test procedures have been omitted.
