9.1 Powertrain Control Module (PCM)

9.1.1 Reset Keep Alive Memory (KAM)

This procedure will reset the Learned Values stored in the Powertrain Control Module (PCM) such as idle and fuel.

9.1.2 Reset the Diesel Particulate Filter (DPF) Learned Values

This procedure must be carried out if a new diesel particulate filter is installed

The powertrain control module will continually learn the characteristics of certain components over time. There may be differences in the characteristics from the old and new components which will result in differences in the learned values. If a new component is installed the difference in learned values may result in poor driveability or set a diagnostic trouble code. This service function will reset the learned values of the old component. The learning process of the new component may occur immediately or over a number of drive cycles.

9.1.3 Reset the Water in Fuel ( WIF ) Warning Indicator

Execute this procedure only if water is detected in the fuel. After performing this procedure the WIF warning indicator is extinguished.

9.1.4 Reset the Knock Sensor Learned Values

Execute this procedure only if a full set of replacement injectors has been fitted.
The engine must not be running.

9.1.5 Reset the Fuel Metering Valve Learned Values

Execute this procedure if High Pressure Fuel Pump has been renewed.
The engine must not be running.

9.1.6 Reset the Intake Air Throttle Valve Learned Values

Execute this procedure if Intake Air Throttle Valve has been installed.

9.1.7 Reset the Exhaust Gas Recirculation ( EGR ) Valve Learned Values

Execute this service function if a new exhaust gas recirculation valve has been Installed.

9.1.8 Reset the Differential Pressure Sensor Learned Values

This procedure will return the learned values back to the nominal settings.

9.1.9 Reset the High Pressure Fuel System Learned Values

This service function must be performed if any new components associated with the high pressure fuel pressure system have been installed.

The powertrain control module will continually learn the characteristics of certain components over time. There may be differences in the characteristics from the old and new components which will result in differences in the learned values. If a new component is installed the difference in learned values may result in poor driveability or set a diagnostic trouble code. This service function will reset the learned values of the old component. The learning process of the new component may occur immediately or over a number of drive cycles.

9.1.10 Fuel Injector Correction Factors

Execute this procedure if a Fuel Injector has been replaced.

9.1.11 Relearn Vehicle Data

Execute this procedure to force a previously configured PCM to relearn new configuration data from BCM.

9.1.12 Reset the Mass Air Flow ( MAF ) Sensor Learned Values

Execute this service function if a new mass air flow sensor has been installed.

9.1.13 Reset the Fuel Pressure Relief Valve Open Count Learned Value

This procedure clears the counters that store the total number of times the fuel rail pressure relief valve has opened.

9.1.14 Reset the Fuel Pressure Relief Valve Open Duration Learned Value

This procedure clears the counters that store the total time the fuel rail pressure relief valve has opened.

9.1.15 Speed Limiter

This procedure sets maximum vehicle speed.
