Test TC-48A - No CCD Messages From Body Control Module (BCM) (DTC 66)

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY . For wiring diagrams, see WIRING DIAGRAMS section. After each repair, perform TEST VER-2 .

NOTE: Chrysler Collision Detection (CCD) bus test is automatic.

Turn ignition on. Using DRB, select BODY SYSTEM and then BODY CONTROLLER. If DRB does not display BUS OPERATIONAL, see VEHICLE COMMUNICATIONS TESTS in TESTS W/CODES - BODY CONTROL COMPUTER article in the ENGINE PERFORMANCE section. If DRB displays BUS OPERATIONAL, go to next step.
If DRB displays NO RESPONSE, see TESTS W/CODES - BODY CONTROL COMPUTER article in the ENGINE PERFORMANCE section. If DRB does not display NO RESPONSE, go to next step.
Using DRB, select ENGINE and erase trouble codes. Start engine. Allow engine to idle for one minute. Read trouble codes. If DRB displays NO CCD MESSAGES FROM BCM, go to step 6). If DRB does not display NO CCD MESSAGES FROM BCM, go to next step.
At this time, the condition required to set trouble code is not present. NO CCD MESSAGES FROM BCM trouble code sets when Powertrain Control Module (PCM) does not receive any messages from BCM across CCD bus for 30 seconds. Possible causes are: CCD bus failure, open CCD (+) circuit, open CCD bus (-) circuit, no power to body control module, failed PCM, or failed BCM. Go to next step.
Inspect wiring and connectors. Repair as required. If wiring and connectors are okay, see INACTIVE TROUBLE CODE CONDITION in this article. Test is complete.
If DRB displays NO CCD MESSAGES FROM BCM in step 3), turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Disconnect Body Control Module (BCM) Bone connector. BCM is located behind right kick panel. Go to next step.
Using an external ohmmeter, check resistance of White/Black wire between PCM connector terminal No. 46 and BCM Bone connector terminal No. 7. If resistance is more than 5 ohms, repair open White/Black wire. If resistance is more than 5 ohms, go to next step.
Using an external ohmmeter, check resistance of Violet/Brown wire between PCM connector terminal No. 26 and BCM Bone connector terminal No. 8. If resistance is more than 5 ohms, repair open Violet/Brown wire. If resistance is more than 5 ohms, replace PCM.
