Information:
System Operation Description:Use this test if there are intermittent engine shutdowns or if a difficulty in starting is not accompanied by loss of electrical accessories. Engine shutdowns that are accompanied by a loss of other electrical accessories indicate a problem in the keyswitch. This does not indicate a problem in the wiring at the engine's Electronic Control Module (ECM). Verify that there are no problems with the starting system or the charging system before you use this test.Use this procedure to troubleshoot the electrical system if a problem is suspected with the power to the engine ECM or if any one of the diagnostic codes in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
Code and Description Conditions which Generate this Code System Response
168-0 Electrical System Voltage high - most severe (3) The battery supply voltage is greater than 32 VDC, for a 24 volt system, for 0.5 seconds.
The battery supply voltage is greater than 16 VDC, for a 12 volt system, for 0.5 seconds.
The engine's ECM has been powered for three seconds.
The engine is not being cranked. The code is logged.
168-1 Electrical System Voltage low - most severe (3) The battery supply voltage is less than 18 VDC, for a 24 volt system, for 0.5 seconds.
The battery supply voltage is less than 9 VDC, for a 12 volt system, for 0.5 seconds.
The engine's ECM has been powered for three seconds.
The engine is not being cranked.
168-2 Electrical System Voltage erratic, intermittent, or incorrect The engine is running. The battery voltage falls below 6 VDC and the voltage returns above 9 VDC for three voltage readings in the last seven seconds. Unswitched battery voltage is supplied to the ECM at P1-48, P1-52, and P1-53. The negative battery is supplied to the ECM at P1-61, P1-63, and P1-65. The ECM receives the input from the keyswitch at P1-70 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 ECM continuously receives battery voltage through the circuit breaker for the engine ECM.The engine ECM requires the keyswitch to be in the ON position in order to maintain communications with Caterpillar Electronic Technician (ET).

Schematic for the electrical power supply circuit
The connection of any electrical equipment and the disconnection of any electrical equipment may cause an explosion hazard which may result in injury or death. Do not connect any electrical equipment or disconnect any electrical equipment in an explosive atmosphere.
Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove electrical power from the engine ECM.
