No Termination

NOTE: For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST VER-1  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
NOTE: Ignition off during bus test is most common cause for this trouble code.
  1. Turn ignition off. Access Body Control Module (BCM) 22-pin connector. BCM is connected to junction block. Do not disconnect connector. Using jumper wire connected to ground, backprobe BCM 22-pin connector between terminal No. 3 (Violet/Gray wire) on Breeze, Cirrus and Stratus or terminal No. 1 (Violet/Brown wire) on Sebring Convertible. Using scan tool, select BODY, BODY COMPUTER, then SYSTEM TEST. Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open Violet/Gray or Violet/Brown wire. If scan tool displays BUS SHORT TO GROUND, go to next step.
  2. Move jumper wire to BCM 22-pin connector, terminal No. 13 (White/Dark Green wire) on Breeze, Cirrus and Stratus or terminal No. 11 (White/Dark Blue wire) on Sebring Convertible. Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open White/Dark Green or White/Dark Blue wire. If scan tool displays BUS SHORT TO GROUND, go to next step.
    3. NOTE: The resistance measurement in next 2 steps are performed at BCM, not at connectors.
  3. Turn ignition off. Disconnect scan tool from DLC. Disconnect BCM from junction block. Using an external ohmmeter, measure resistance between BCM pins CCD BUS (+) and (-) terminals for 22-pin connector. See CCD BUS CIRCUIT IDENTIFICATION  table. If resistance is not 100-140 ohms on all circuits, replace BCM. If resistance is 100-140 ohms on all circuits, go to next step.
  4. Measure resistance between BCM pins CCD BUS (+) and (-) terminals for 14-pin connector. See CCD BUS CIRCUIT IDENTIFICATION  table. If resistance is not 100-140 ohms on all circuits, replace BCM. If resistance is 100-140 ohms on all circuits, replace scan tool cable or scan tool.
