Event Code List

Usage:

525C 525

Event Identifier Codes (EID) alert the operator that an abnormal machine operating condition such as a high system voltage or inappropriate parking brake engagement has occurred.

When the ECM activates an event code, the operator will be alerted by the Monitor. Some events will be logged by the ECM and can be viewed with the Monitor or the Caterpillar Electronic Technician (ET) service tool.

Event codes are activated in one of four warning levels according to the severity of the condition. The warning levels and the operator action that is required are shown in the following table.

WARNING OPERATION
Warning Category	Warning Indications ⁽¹⁾			Required Operator Action	Possible Result ⁽²⁾
Warning Category	Alert Indicator Flashes ⁽³⁾	Action Lamp Flashes	Action Alarm Sounds	Required Operator Action	Possible Result ⁽²⁾
1	X			No immediate action required. The system needs attention soon.	No harmful or damaging effects.
2	X	X		Change machine operation or perform maintenance to the system.	Severe damage to components.
2-S	X	X	X ⁽⁴⁾	Immediately change the machine operation.	Severe damage to machine components.
3	X	X	X ⁽⁵⁾	Immediately perform a safe engine shutdown.	Operator injury or severe damage to components.

⁽¹⁾	The warning indications which are active, are marked with an "X".
⁽²⁾	This is the possible result if no operator action is taken.
⁽³⁾	At a 10 Hz rate.
⁽⁴⁾	The alarm is on continuously.
⁽⁵⁾	Pulsating alarm.

When an EID is activated by the ECM, the following information should be recorded.

Obtain the following information from the operator:
- The event and the time of the event
- Determine the engine's operating conditions at the time of the event. Conditions such as engine rpm and load may be important.
- Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
Verify that the event is not due to normal machine operation. Verify that the event is not due to error of the operator.
Check all fluid levels and all oil levels.
Troubleshoot and repair any active diagnostic codes.

The following table lists the event codes that apply to the machine control system. The cause of the active EID is listed. Use the Cat ET service tool in order to determine the event codes that are active or logged.

Event Codes
EID	Warning Level	Description	Cause
0043	2	Low System Voltage Warning	The battery is not charging. Check for diagnostic codes relating to system voltage or alternator output. To troubleshoot, check associated diagnostic codes that may occur with this event code.
0050	2	High System Voltage Warning	The system voltage is higher than normal. Check for diagnostic codes relating to system voltage or alternator output.
0179	2	Alternator Not Charging	Check tension on drive belt of alternator. Check electrical connections of alternator circuit.
