3500B Engines for Caterpillar Built Power Modules with the ADEM 3 Electronic Control Module Caterpillar

Event Codes

Usage:

Engine Monitoring

The Electronic Control Module (ECM) monitors the operating parameters of the engine. The ECM will generate an event code if a specific engine parameter exceeds an acceptable range that is defined by the engine monitoring system. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".

Cross-Reference Information for Event Codes

Event codes are generated when abnormal operating conditions exist. Table 1 is a list of the event codes for the engine. The event codes are cross-referenced with the appropriate procedure that can be used to troubleshoot the code.

Parts of the Event Code

Event Code - The "E" identifies the code as an event code. The "XXX(X)" represents a numeric identifier for the event code. The fourth "(X)" assigns one of three levels to the active event code according to the severity of the abnormal system condition. This is followed by a description of the code. Refer to the following example:

E360(1) Low Oil Pressure
E360(2) Low Oil Pressure
E360(3) Low Oil Pressure

The definition for the levels of severity for an event are defined below:

Table 2
Indicators (1), (2), and (3)
Warning Category Indicator	Severity
(1)	"Least Severe"
(2)	"Moderate Severity"
(3)	"Most Severe"

Active Event Codes

An active event code represents a problem with engine operation. Correct the problem as soon as possible.

Active event codes are listed in ascending numerical order. The code with the lowest number is listed first.

Illustration 1 is an example of the operating range of a sensor.

Show/hide table




Illustration 1	g01365757
Example of the typical operating range of a sensor (1) This area represents the normal operating range of the engine parameter. (2) In these areas, the engine is operating in an unsafe operating range of the monitored parameter. An event code will be generated for the monitored parameter. The sensor circuit does not have an electronic problem. (3) In these areas, the signal from the sensor is outside of the operating range of the sensor. The sensor circuit has an electronic problem. A diagnostic code will be generated for the sensor circuit. Refer to Troubleshooting, "Diagnostic Trouble Codes" for additional information on diagnostic codes.

Logged Event Codes

When the Electronic Control Module (ECM) generates an event code, the ECM may log the event code in permanent memory. The ECM has an internal diagnostic clock. The ECM will record the following information when an event code is generated:

The hour of the first occurrence of the code
The hour of the last occurrence of the code
The number of occurrences of the code

Logged events are listed in chronological order. The most recent event code is listed first.

This information can be helpful for troubleshooting intermittent problems. Logged codes can also be used to review the performance of the engine.

Clearing Event Codes

A code is cleared from memory when one of the following conditions occur:

The code does not recur for 100 hours.
A new code is logged and there are already ten codes in memory. In this case, the oldest code is cleared.
The service technician manually clears the code.

Always clear logged event codes after investigating and correcting the problem which generated the code.

Troubleshooting

For basic troubleshooting of the engine, perform the following steps in order to diagnose a malfunction:

Obtain the following information about the complaint:
- The event and the time of the event
- Determine the conditions for the event. The conditions will include the engine rpm and the load.
- Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
- Determine whether any additional events occurred.
Verify that the complaint is not due to normal engine operation. Verify that the complaint is not due to error of the operator.
Narrow the probable cause. Consider the operator information, the conditions of operation, and the history of the engine.
Perform a visual inspection. Inspect the following items:
- Fuel supply
- Oil level
- Oil supply
- Wiring
- Connectors

Be sure to check the connectors. This is very important for problems that are intermittent. Refer to Troubleshooting, "Electrical Connectors - Inspect".

If these steps do not resolve the problem, refer to Table 1 for the procedure to troubleshoot the event code.

Parameter Settings of the Engine Monitoring System

The default settings for the parameters are programmed at the factory. If the delay time or the trip point are programmable, the minimum and maximum ranges will be listed in Table 3.

The parameter settings for the engine monitoring system can also be viewed on Caterpillar Electronic Technician (ET). In order to view the parameters of the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".

⁽¹⁾	The ECM will derate the engine in 3 percent increments for every 305 m (1000 ft) increase in elevation up to a maximum derate of 35 percent.
⁽²⁾	The ECM limits the fuel if the engine is operated above the default altitude of 762 m (2500 ft). The ECM will derate the engine in 3 percent increments for every 305 m (1000 ft) increase in elevation up to a maximum derate of 35 percent.
⁽³⁾	If the trip point for the derate is exceeded the derate will reduce power linearly from 0 % to a maximum of 25 % over a period of 480 seconds.
⁽⁴⁾	If the trip point is exceeded, engine power will be derated 2% for each 15 second time period. The maximum derate is 20%.
⁽⁵⁾	Refer to the Performance and Ratings manual.
⁽⁶⁾	Derates power 2% per kPa to a maximum derate of 25%. This derate will not reset, if the value falls below the value of the trip point.
⁽⁷⁾	The engine must be operated at an average load that is greater than 20 % for ten minutes. When the average load is greater than 20% and the coolant temperature is below 80 °C (176 °) for 5 seconds, a warning will occur. To deactivate the warning, the 10 minute average load must drop below 20% or the coolant temperature must be greater than 85 °C (185 °F).
⁽⁸⁾	Refer to the oil pressure map in Illustration 2 for engines that are rated up to 1300 rpm. Refer to the oil pressure map in Illustration 3 for engines that are rated at 1301 rpm and above.
