Diagnosis & Testing

Begin the system diagnosis with Diagnostic System Check-Vehicle. The Diagnostic System Check-Vehicle will provide the following information:



The identification of the control modules which are not communicating through the serial data circuit.
 
The identification of any stored Diagnostic Trouble Codes (DTCs) and their status.
 

The use of the Diagnostic System Check-Vehicle will identify the correct procedures to begin vehicle diagnosis. These must be performed before system DTC or symptom diagnosis.

Diagnostic System Check-Vehicle
  1. Before beginning vehicle diagnosis, the following preliminary inspections/tests must be performed:

    Ensure that the battery is fully charged.
     
    Ensure that the battery cables are clean and tight.
     
    Inspect for any open fuses.
     
    Ensure that the grounds are clean, tight, and in the correct location.
     
    Inspect the easily accessible systems or the visible system components for obvious damage or conditions that could cause the concern. This would include checking to ensure that all connections/connectors are fully seated and secured.
     
    Inspect for aftermarket devices that could affect the operation of the system.
     
    Search for applicable service bulletins.
     

  2.  
  3. Install a scan tool. Verify that the scan tool powers up.
  4.  
  5. Ignition ON, Engine OFF, verify communication with all of the control modules on the vehicle.
    NOTE
    Open the driver's door to ensure Retained Accessory Power Mode (RAP) is inactive during this test. The engine may start during this test. Turn the engine OFF as soon as the crank power mode has been observed.

  6.  
  7. Access the Power Mode parameter on the scan tool. Verify the power mode parameter matches all the ignition switch positions.
  8.  
  9. Attempt to start the engine. Verify that the engine cranks.
  10.  
  11. Attempt to start the engine. Verify the engine starts and idles.
    NOTE
    Do not clear any DTCs unless instructed to do so by a diagnostic procedure.


    NOTE
    If any DTCs are Powertrain related DTCs, select Capture Info in order to store the DTC information with the scan tool.

  12.  
  13. Use the appropriate scan tool selections to obtain DTCs from each of the vehicle modules. Verify there are no DTCs reported from any module.
  14.  
  15. If any DTCs are present, refer to Diagnostic Trouble Code (DTC) List - Vehicle and diagnose any current DTCs in the following order:
