CHECK FOR AN ACTIVE DTC
1. With the scan tool, read Powertrain Control Module 2 (PCM-2) DTCs and Freeze Frame Data and record on the repair order.
2. Using the recorded Freeze Frame Data and the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
3. With the scan tool, read DTCs.
  Is the DTC active or pending?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK THE (K619) ACTIVE EXHAUST CONTROL CIRCUIT FOR A PARTIAL SHORT TO A VOLTAGE SUPPLY
1. Turn the ignition off.
2. Disconnect the Active Exhaust Control Solenoid harness connector.
3. Disconnect the PCM-2 C2 harness connector.
4. Check for continuity between the (K619) Active Exhaust Control circuit and all other circuits at the PCM-2 C2 harness connector.
  Is there continuity between the (K619) Active Exhaust Control circuit and any other circuit?
  
  Yes
  - Repair the (K619) Active Exhaust Control circuit for a short to the circuit that showed continuity.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

6. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 4
  No
  - Replacing the Active Exhaust Control Solenoid repaired the fault.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all PCM-2 harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
5. Connect all PCM-2 harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Connect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Connect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
10. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
