REGULATOR GP-VOLTAGE 1348277 - Caterpillar

Tampering with the electronic system installation or the OEM wiring installation can be dangerous and could result in personal injury or death and/or engine damage.
Electrical Shock Hazard. The electronic unit injectors use DC voltage. The ECM sends this voltage to the electronic unit injectors. Do not come in contact with the harness connector for the electronic unit injectors while the engine is operating. Failure to follow this instruction could result in personal injury or death.
This engine has a comprehensive, programmable Engine Monitoring System. The Electronic Control Module (ECM) has the ability to monitor the engine operating conditions. If any of the engine parameters extend outside an allowable range, the ECM will initiate an immediate action.The following actions are available for engine monitoring control:
Warning
Derate
ShutdownThe following monitored engine operating conditions have the ability to limit engine speed and/or the engine power:
Engine Coolant Temperature
Engine Oil Pressure
Engine Speed
Intake Manifold Air Temperature
High exhaust Temperature
High Fuel Rail Temperature
Low Coolant LevelThe Engine Monitoring package can vary for different engine models and different engine applications. However, the monitoring system and the engine monitoring control will be similar for all engines.Note: Many of the engine control systems and display modules that are available for Caterpillar Engines will work in unison with the Engine Monitoring System. Together, the two controls will provide the engine monitoring function for the specific engine application. Refer to the Troubleshooting for more information on the Engine Monitoring System.
