Lifetime Totals Stored In The ECM
The ECM maintains engine total data for the following parameters. Engine Hours is engine running hours (it does not include time when the ECM is powered ON without the engine running). Distance data requires a vehicle speed sensor connected to the ECM (the same sensor used for ECM vehicle speed). PTO Hours and PTO Fuel are logged when engine rpm is set using the Cruise Control switches and the engine is operating under some load, or when the Dedicated PTO On/Off Switch is ON and vehicle speed is within range of the Idle/PTO Vehicle Speed Limit Parameter. Idle Hours and Idle Fuel can include time when the engine speed is set using the Cruise switches and the vehicle speed is within range of the Idle/PTO Vehicle Speed Limit Parameter, but the engine is not operating under load.Maintenance Indicator Data
The ECM records the Lifetime Data Totals when a maintenance reset occurs for three levels of maintenance - PM1, PM2, and Coolant Flush/Fill. The previous maintenance point is used by the ECM to calculate when the next maintenance is due.The Maintenance Indicator feature is programmable to hours or distance. The PM1 maintenance is programmable to OFF, Automatic-Distance, Automatic-Hours, Manual-Distance, or Manual-Hours.If PM1 is programmed to Automatic (Distance or Hours), the ECM calculates the next maintenance due by considering the vehicle operation history from the previous maintenance interval. If the vehicle has a history of poor fuel economy, the maintenance indicator will occur sooner than a vehicle with better fuel economy.The ECM also uses the Engine Oil Capacity, with a larger capacity providing a longer maintenance interval. Engine Oil Capacity is programmed in quarts. If the PM1 Maintenance Indicator is programmed to Manual, the owner can program in their own specific maintenance mileage or time interval. PM2 and Coolant Flush/Fill intervals are determined by the factory.CAT ID
The Caterpillar Driver Information Display (CAT ID) is available to provide operating information to the driver about the engine such as engine rpm, coolant temperature, boost pressure, etc, as well as engine diagnostic codes with the PID-FMI and a brief text description.CAT ID will also allow changing/resetting of certain operating parameters if the ECM is programmed to access these parameters as well as PM1 Reset and Theft Deterrent.The Theft Deterrent feature allows the driver to input a four character password to shut the engine down and/or prevent the engine from restarting until the four character password is successfully entered. For CAT ID to function properly an AUG96 or later Personality Module is required in the ECM. The CAT ID must also have the EEPROM chip capable of supporting communication with 3100 HEUI engines, software version 1.3 or later. The version number is displayed initially on powerup of CAT ID.Programmable Parameters
Certain parameters that affect 3100 HEUI Diesel Truck Engine operation may be changed with electronic service tools. The parameters are stored in the ECM, and are protected from unauthorized changes by passwords. These parameters are either "System Configuration Parameters" or "Customer
