QT Step 1: Powertrain Control Module (PCM) Quick Test

QT1 CARRY OUT THE PCM QUICK TEST

Note: If the vehicle was brought in with an emission compliance failure symptom GO to Pinpoint Test EM Tests EM: Emission Compliance

Complete the preliminary checks looking for obvious concerns that may relate to the symptom. Check items such as those listed below:

^ Related electrical connectors or fuses
^ Vacuum lines (leaks routing)
^ Air intake system (leaks restrictions)
^ Fuel quality (octane contamination winter/summer blend)
^ Cooling system (engine operating at proper temperature) Access any related OASIS or TSB information (if available).

Note: For applications that use a stand-alone transmission control module (TCM) the PCM does not output TCM related DTCs. Refer to Automatic Transaxle/Transmission for diagnosis and testing.

Note: If unable to access the DTCs or any diagnostic tool communication concern exists GO to Pinpoint Test QA. Tests QA: Unable to Activate Self-Test/Network Communication Error

For additional information on retrieving MIL and non-MIL DTCs refer to Diagnostic Methods Continuous Memory Self-Test. Scan Tool Testing and Procedures

Complete the PCM Quick Test to access any DTCs. Note any key on engine off (KOEO) key on engine running (KOER) (if engine runs) and Continuous Memory (MIL and non-MIL) DTCs.
