Electronic Engine Controls - INGENIUM I4 2.0L Diesel (G2006313): Operation: Diagnostics

The Powertrain Control Module (PCM) stores each fault as a Diagnostic Trouble Code (DTC). The DTC and associated environmental and freeze frame data can be read using the approved diagnostic equipment. The approved diagnostic equipment can also read:

• Real time data from each sensor
• The adaption values currently being employed
• The current fueling settings
• The current ignition settings
• The current idle speed settings.

The freeze frame data can vary depending on the fault. Core freeze frame data for every DTC includes:

• Power mode
• Time
• Distance
• Startup battery voltage.

Specific sets of data are linked to each DTC. The selected data set will give the most useful supporting data to diagnose the fault.
