Information:
Conditions Which Generate This Code:This diagnostic code is associated with an electrical system voltage that is below normal. The FMI 04 means that the engine electronic control module (ECM) has determined that the electrical system voltage is below normal.
Illustration 1 g00689475
Simplified System Schematic For Battery VoltageThe EMCP II+ monitors the battery voltage in order to protect the EMCP II+ from a battery problem or from a charging problem. The battery voltage is received from the engine electronic control module (ECM) by the CAT data link. If you receive a CID 168 E diagnostic code, refer to Troubleshooting, RENR2227, "3406E and 3456 Generator Set Engines". The GSC+ treats a CID 168 FMI 04 as an alarm diagnostic code. The threshold for a CID 168 FMI 04 for battery voltage is less than 18 DCV for a 24 volt system. The threshold for a CID 168 FMI 04 for battery voltage is less than 18 DCV for a 32 volt system.

POSSIBLE CAUSES FOR THE CID 168 DIAGNOSTIC CODES    
Location of the Display for the Diagnostic Code     Diagnostic Code     Battery Voltage (Threshold)
24 Volt (System Voltage)     Battery Voltage (Threshold)
32 Volt (System Voltage)    
Engine ECM     CID 168 E 00     The engine is running and the battery voltage is greater than 32 DCV more than two seconds.        
Engine ECM     CID 168 E 01     The engine is not running and the battery voltage is less than 9 DCV for more than two seconds.        
Engine ECM     CID 168 E 02     The engine is not running. The battery voltage is less than 9 DCV for a period of .07 seconds. The battery voltage then returns to 9 DCV or the battery voltage rises above 9 DCV.
A second cause for this diagnostic is possible. The battery voltage will drop below 9 DCV three times in seven seconds.        
GSC+     CID 168 FMI 03         Regardless of engine status, the battery voltage is greater than the P007 limit.    
GSC+     CID 168 FMI 04         Regardless of the engine status, the battery voltage is less than 18 DCV.    The setpoint for the system voltage (P007) specifies the battery voltage.24 - 24 Volt System32 - 32 Volt SystemNote: The GSC+ does not receive battery power when the ECS is in the OFF/RESET position. When contact 6 is connected to one of the contacts (8, 9, 10), the GSC+ receives battery power when the ECS is in the OFF/RESET position. Before beginning this procedure, ensure that the following steps have been performed:
VERIFY THE DIAGNOSTIC CODE.
Make sure that the CID 168 FMI 04 is shown on the display.
Enter service mode.
Turn the ECS to the STOP position.
Program setpoint P023 to 0.
Turn the ECS to the OFF/RESET position. Note: When Program Setpoint P023 is set to 0, the GSC+ is programmed for an MUI engine. The engine's electronic control module (ECM) is eliminated as a possibility of the
