  1. If power door systems diagnostic system check has been performed, go to next step. If power door systems diagnostic system check has been performed, go to POWER DOOR SYSTEMS DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM in POWER DOOR LOCKS - CORVETTE article.
  2. Close both doors and turn ignition on. If DOOR AJAR message is displayed on DIC, go to next step. If DOOR AJAR message is no longer displayed on DIC, go to step  6 .
  3. Connect scan tool to DLC and display BCM input data 2 list. If scan tool indicates driver's or passenger's door is ajar, go to next step. If scan tool does not indicate driver's or passenger's door is ajar, go to step  13 .
  4. Turn ignition off. Remove door panel and disconnect suspect door latch connector C2. Turn ignition on. If DOOR AJAR message is displayed on DIC, go to next step. If DOOR AJAR message is no longer displayed on DIC, go to step  8 .
  5. For driver's door, check for short to ground in Gray/Black wire between BCM and door latch connector C2 terminal "B". For passenger's door, check for short to ground in Black/White wire between ground and door latch connector C2 terminal "C". If short to ground is found and repaired, go to step  14 . If circuit is okay, go to step  12 .
  6. Display BCM input data 2 list on scan tool. Open driver's and passenger's doors. If scan tool does not indicate driver's and passenger's door is ajar, go to next step. If scan tool indicates driver's and passenger's door is ajar, go to step  13 .
  7. Disconnect suspect door latch connector C2. On driver's door, connect a fused jumper wire between door latch connector C2 terminals "B" (Gray/Black wire) and "D" (Black wire). On passenger's door, connect a fused jumper wire between door latch connector C2 terminals "C" (Black/White wire) and "A" (Black wire). See Fig 1 . Turn ignition on. If DOOR AJAR message is displayed on DIC, go to next step. If DOOR AJAR message is no longer displayed on DIC, go to step  9 .
  8. Replace suspect door latch assembly. See DOOR LATCH ASSEMBLY  under REMOVAL & INSTALLATION. After repairs, go to INSTRUMENT PANEL CLUSTER (IPC) DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  9. On driver's door, connect a fused jumper wire between ground and door latch connector C2 terminal "B" (Gray/Black wire) and "D" (Black wire). On passenger's door, connect a fused jumper wire between ground and door latch connector C2 terminal "C" (Black/White wire). Turn ignition on. If DOOR AJAR message is displayed on DIC, go to next step. If DOOR AJAR message is no longer displayed on DIC, go to step  11 .
  10. Repair open in Black wire between suspect door latch and ground. After repairs, go to step  14 .
  11. Repair open or high resistance in Gray/Black or Black/White wire between suspect door latch and BCM. If circuit is okay, go to next step. If faulty circuit is found and repaired, go to step  14 .
  12. Replace Body Control Module (BCM). See BODY CONTROL MODULE (BCM)  under REMOVAL & INSTALLATION. After repairs, go to step  14 .
  13. Replace IPC. See INSTRUMENT PANEL CLUSTER (IPC)  under REMOVAL & INSTALLATION. After repairs, go to next step.
