Diagnostic Test

CHECK FOR AN ACTIVE DTC
WARNING:
On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury.

to perform the High Voltage Power Down procedure.
1. With the scan tool, read Occupant Restraint Controller (ORC) DTCs and record on the repair order.
2. Record the Environmental Data, Snap-Shot Data and any DTCs.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data and Snap-Shot Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read ORC DTCs.
  Did the DTC reset?
  
  Yes
  - Go to 2
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK ALL MODULES FOR COMMUNICATION RELATED DTCS
1. With the scan tool, read DTCs from all modules.
  Are there any communication related DTCs active in any of the modules?
  
  Yes
  - Diagnose the communication related DTCs.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go to 3
CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCS
1. With the scan tool, read DTCs from all high voltage modules.
  Is there more than one high voltage module with active DTCs "Logged Against" the Power Inverter Module (PIM)?
  
  Yes
  - Perform the NO RESPONSE WITH PIM (POWER INVERTER MODULE) diagnostic procedure. Refer to DIAGNOSIS AND TESTING .
  No
  - Go to 4
CHECK RELATED HARNESS CONNECTIONS
NOTE:
The 12.0 volt Battery Cables and High Voltage Disconnect must be disconnected before disconnecting the Accessory Power Module (APM). Failure to follow this instruction may result in damage to the Accessory Power Module (APM).
1. Disconnect all ORC 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.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
  Repair any conditions that are found.
5. Connect all ORC 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. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. With the scan tool, read ORC DTCs.
  Did the DTC return?
  
  Yes
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC in accordance with the Service Information. Refer to CONTROLLER, OCCUPANT RESTRAINT (ORC), REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Test complete.
