System Operation Description:The following diagnostic code indicates a problem with the power supply to the Engine Control Module (ECM):
168-2 ECM Battery Power IntermittentThis code indicates that the battery circuit to the ECM has an intermittent low battery condition. The engine may experience intermittent engine shutdown or complete engine shutdown while the conditions that cause this diagnostic code are present.
244-2 Event Recorder Data LostThe unswitched battery connection has been disconnected from the ECM. This diagnostic code can be caused when the ECM personality module is changed, or when a new ECM is initially installed. The following background information is related to this procedure:The ECM receives electrical power (battery voltage) through the wiring that is supplied by the vehicle manufacturer. The ECM input at connector P1-6 (keyswitched battery connection) receives battery voltage from the keyswitch when the keyswitch is in the ON position or in the START position. When the ECM detects battery voltage at this input, the ECM will power up. When battery voltage is removed from this input, the ECM will power down.The cause of an intermittent power supply to the ECM can occur on either the positive side (unswitched battery) or the negative side (negative battery). Both sides are routed from the ECM to the battery. Route the unswitched battery connection through a dedicated protection circuit.Some vehicles may be equipped with an engine protection shutdown system or with an idle timer shutdown system that interrupts electrical power to the ECM in order to shut down the engine. Also, some vehicles may be equipped with an engine protection shutdown system or an idle timer shutdown system that interrupts electrical power to the keyswitch. The engine protection shutdown system can be an aftermarket device and the idle timer shutdown system can be external to the ECM. Some of these systems will not supply power to the ECM until one of the following conditions is met:
Engine cranking
Acceptable engine oil pressure
Activation of an override switchThese devices may be the cause of intermittent power to the ECM.Usually, battery power to the data link connector is available and the battery power to the cab data link connector is independent of the keyswitch. Therefore, you will be able to power up the Caterpillar Electronic Technician (ET), but you may not be able to communicate with the engine ECM. The engine ECM requires the keyswitch to be in the ON position in order to maintain communications. The ECM may power down a short time after connecting to Cat ET if the keyswitch is in the OFF position. This is normal.For intermittent problems such as intermittent shutdowns that could be caused by vehicle wiring, temporarily bypassing the vehicle wiring may be an effective means of determining the root cause. If the symptoms disappear with the bypass wiring, the vehicle wiring is the cause of the problem. A means of bypassing vehicle wiring is explained in this test procedure. This is especially important for vehicles that do not provide dedicated circuits for the unswitched battery and for
