1996 Chrysler LHSFACTORY OEM SERVICE PROCEDURE
Test TC-97A - No CCD Message From Control Module
NOTE:
For connector terminal ID, see CONNECTOR IDENTIFICATION Directory. For wiring diagram, see WIRING DIAGRAMS
article.
- Using scan tool, erase trouble codes. Start engine. Allow engine to idle for one minute. Using scan tool, read trouble codes. If scan tool displays NO CCD MESSAGES FROM CONTROLLER, go to step 4). If scan tool does not display NO CCD MESSAGES FROM CONTROLLER, go to next step.
- Condition to set trouble code is not present at this time. NO CCD MESSAGE FROM CONTROL MODULE DTC sets if no CCD messages are received from Control Module (BCM) for 30 seconds. Possible causes are: open CCD BUS + or - circuit between modules, BCM is not powered-up, failed BCM or failed Powertrain Control Module (PCM). Go to next step.
- Inspect all related wiring and connectors and repair as necessary. BCM is located in left front corner of engine compartment. If no problems were found with wiring and connectors, see test procedures under INACTIVE TROUBLE CODE CONDITION . Test is complete. Perform TEST VER-2A. If related wiring and connectors were repaired, perform TEST VER-2A.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connectors. Disconnect Control Module (BCM) 14-pin connector. BCM is located in left front corner of engine compartment. Using an external ohmmeter, check resistance of CCD BUS + circuit between BCM connector terminal No. 8 and PCM terminal No. 59. If resistance less than 5 ohms, go to next step. If resistance 5 ohms or more, repair open CCD BUS + circuit between BCM and PCM. Perform TEST VER-2A.
- Using an ohmmeter, check resistance of CCD BUS - circuit between BCM connector terminal No. 7 and PCM connector terminal No. 60. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open CCD BUS - circuit between BCM and PCM. Perform TEST VER-2A.
- Reconnect BCM 14-pin connector. Turn ignition on. Using scan tool, select CONTROL MODULE. If scan tool displays NO RESPONSE, replace BCM. Perform TEST VER-2A. If scan tool does not display NO RESPONSE, replace PCM. Perform TEST VER-2A.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • 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.
