Electronic Engine Controls - INGENIUM I6 3.0L Petrol (G2300004): 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 a Jaguar Land Rover (JLR) approved diagnostic equipment.

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.

The JLR approved diagnostic equipment can also read the following:

• 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.

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