System Schematic For Battery Voltages On EUI And PEEC EnginesThe 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, " G3500C Engines" or Troubleshooting, " G3408C and G3412C Engines". The GSC+ treats a CID 168 FMI 4 as an alarm diagnostic code. The threshold for a CID 168 FMI 04 for battery voltage is less than 18 DCV for 24 volt system. The threshold for a CID 168 FMI 4 for battery voltage is less than 18 DCV for a 32 volt system.

POSSIBLE CAUSES FOR CID 168 DIAGNOSTIC CODES    
The Location that the Diagnostic Code is Displayed On     Diagnostic Code     Battery Voltage Thresholds
(24 Volt System)     Battery Voltage Thresholds
(32 Volt System)    
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 greater). The other possible diagnostic code cause is that the battery voltage goes 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. Test Step 1. CHECK THE SYSTEM'S VOLTAGE.
Turn the ECS to the STOP.
Measure the voltage across the battery terminals.Expected Result:For a 24 volt system, the voltage should be between 24.8 DCV and 29.5 DCV. For a 32 volt system, the voltage should be between 33.1 DCV and 39.3 DCV.Results:
OK - For a 24 volt system, the voltage is 24.8 DCV to 29.5 DCV. For a 32 volt system, the voltage is 33.1 DCV to 39.3 DCV. Proceed to 2.
NOT OK - For 24 volt systems, the voltage is not between 24.8 DCV to 29.5 DCV. For a 32 volt system, the voltage is not between 33.1 DCV to 39.3 DCV. The problem is in the charging system.Repair: Proceed to Testing and Adjusting, "Charging System - Test". Stop.Test Step 2. COMPARE THE VOLTAGE BETWEEN DC CONNECTOR TERMINALS AND THE BATTERY VOLTAGE.
Turn the ECS to the STOP position.
Measure the battery voltage across the battery terminals. Take note of the battery voltage.
Measure the voltage between terminal 1 on the DC connector and terminal 11. Repeat the measurement between terminal 1 and terminal 12. Repeat the measurement between terminal 2 and terminal 11. Repeat the measurement between terminal 2 and terminal 12. Take note of the voltages.
Compare the voltage measured at the battery with the voltage measured between the DC connector terminals.Expected Result:The voltage measured at the battery and the voltage measured between the DC connector terminals.Results:
OK - The voltage measured at the battery and the voltage measured between the DC connector terminals are within 2.0 DCV of each other. Proceed to Test Step 3.
NOT OK - The voltage measured at the battery and the voltage measured between the DC connector terminals are NOT within 2.0 DCV of each other. The wiring harness is not correct.Repair: Repair the wiring harness or replace the wiring harness. Proceed to Test Step 10.Test Step 3. COMPARE THE VOLTAGE BETWEEN THE DC CONNECTOR TERMINALS AND THE ECS.
Turn the ECS to the STOP position.
Measure the voltage between terminal 1 on the DC connector and terminal 11. Repeat the measurement between terminal 1 and terminal 12. Repeat the measurement between terminal 2 and terminal 11. Repeat the measurement between terminal 2 and terminal 12. Take note of the voltages.
Measure the voltage at terminal 6 on the ECS. Take note of the voltage.
Compare the voltage that was measured at the DC connector terminals with the voltage that was measured at the ECS.Expected Result:The voltage that was measured at the DC connector terminals and the voltage that was measured at the ECS are within 2.0 DCV of each other.Results:
OK - The voltage that was measured at V and the voltage that was measured at the ECS are within 2.0 DCV of each other. Proceed to Test Step 4.
NOT OK - The voltage that was measured at the DC connector terminals and the voltage that was measured at the ECS are NOT within 2.0 DCV of each other. The wiring harness is not correct. Repair: Repair the wiring harness or replace the wiring harness. Proceed to Test Step 10.Test Step 4. CHECK THE CONTINUITY OF THE ECS (TERMINAL 7).
There is a jumper wire on the ECS that attaches terminal 6 to terminal 9. Remove this wire.
Place the ECS in the "OFF/RESET" position.
With an ohmmeter, measure the resistance between ECS terminal 6 and ECS terminal 7. Continue to measure the resistance between ECS terminal 6 and ECS terminal 7 while the ECS is rotated to
