Powertrain Control Module Adaptions

WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) has the ability to adapt the input values it uses to control certain outputs. This capability maintains engine refinement and provides the engine emissions remain within the legislated limits.

If the PCM is replaced, the new PCM will relearn the adaptions as the vehicle is driven. Some components require a reset of adaptions when replaced and this can be achieved using a Jaguar Land Rover approved diagnostic equipment.

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 approved diagnostic equipment. It can be also read real time data from each sensor, the adaption values currently being employed and the current fueling, ignition and 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 and 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.
