Begin the system diagnosis with Diagnostic System Check - Engine Controls (2.2 L) or Diagnostic System Check - Engine Controls (2.4 L) in Engine Controls. The Diagnostic System Check - Engine Controls will provide the following information:
| • | The identification of the control modules which command the system |
| • | The ability of the control modules to communicate through the serial data circuit |
| • | The identification of any stored diagnostic trouble codes (DTCs) and the codes statuses |
The use of the Diagnostic System Check - Engine Controls will identify the correct procedure for diagnosing the system and where the procedure is located.
