CCD Short To Ground

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: For appropriate wire color tracers (i.e., Black/*), see appropriate wiring diagram in BODY CONTROL COMPUTER - INTRODUCTION article.
  1. Connect backprobe jumper wire between Data Link Connector (DLC) ground terminals No. 4 (Black/* wire) and No. 5 (Black/* wire). If scan tool does not display BUS SHORT TO GROUND, repair open ground wire. See appropriate wiring diagram in BODY CONTROL COMPUTER - INTRODUCTION article. If scan tool displays BUS SHORT TO GROUND, go to next step.
  2. Turn ignition off. Disconnect Transmission Control Module (TCM), if equipped. TCM is located at left front corner of engine compartment, next to power distribution center. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace TCM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  3. Turn ignition off. Disconnect Powertrain Control Module (PCM). PCM is located next to air cleaner. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace PCM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  4. Turn ignition off. Disconnect instrument cluster. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace instrument cluster. If scan tool displays BUS SHORT TO GROUND, go to next step.
  5. Turn ignition off. Disconnect Smart Key Immobilizer Module (SKIM), if equipped. SKIM is located at ignition lock cylinder. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace SKIM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  6. Turn ignition off. Disconnect anti-lock brake controller module. Anti-lock brake controller module is mounted on right inner fender panel of engine compartment. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace anti-lock brake controller module. If scan tool displays BUS SHORT TO GROUND, go to next step.
  7. Turn ignition off and wait 5 minutes. Disconnect Air Bag Control Module (ACM) 13-pin connector. ACM is located under center console. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace ACM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  8. Disconnect Body Control Module (BCM) 22-pin connector. BCM is connected to junction block. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, go to step  12 . If scan tool displays BUS SHORT TO GROUND, go to next step.
  9. Disconnect BCM 10-pin instrument panel connector. Measure resistance between ground and BCM 10-pin connector terminal No. 8 (Black/Light Green wire). If resistance is less than 5 ohms, repair short to ground in Black/Light Green wire. If resistance is 5 ohms or more, go to next step.
  10. Disconnect scan tool from DLC. Measure resistance between ground and DLC terminal No. 3 (Violet/Gray wire on Breeze, Cirrus and Stratus and Violet/Brown wire on Sebring Convertible). If resistance is less than 5 ohms, repair Violet/Gray or Violet/Brown wire for short to ground. If resistance is 5 ohms or more, go to next step.
  11. Measure resistance between ground and DLC terminal No. 11 (White/Dark Green on Breeze, Cirrus and Stratus and White/Dark Blue wire on Sebring Convertible). If resistance is less than 5 ohms, repair White/Dark Green wire or White/Dark Blue wire for short to ground. If resistance is 5 ohms or more, replace scan tool cable or scan tool as necessary.
  12. Turn ignition off. Using an external ohmmeter, measure resistance between ground and each CCD BUS (+) terminals on BCM 22-pin connector. See CCD BUS CIRCUIT IDENTIFICATION  table. If resistance of any terminals are less than 5 ohms, repair short to ground in appropriate circuit. If resistance of all terminals are 5 ohms or more, go to next step.
  13. Measure resistance between ground and each CCD BUS (-) terminals on BCM 22-pin connector. See CCD BUS CIRCUIT IDENTIFICATION  table. If resistance of any terminals are less than 5 ohms, repair short to ground in appropriate circuit. See appropriate wiring diagram in BODY CONTROL COMPUTER - INTRODUCTION article. If resistance of all terminals are 5 ohms or more, replace BCM.
