( 1 ) For the VIMS ECM, the MID is 049. This table pertains only to faults with a MID of 049.

Note: Table 1 refers to the diagnostic codes for the VIMS ECM only. The diagnostic codes

for the VIMS ECM are shown on the display area of the Vital Information ManagementSystem (VIMS). The module identifier (MID) tells the service person the ECM that is

sending the diagnostic code. The MID for the VIMS ECM is 049. The information in table

1 only refers to diagnostic codes with a MID of 049. The MID of other electronic controlmodules or components on a particular machine are listed on the electrical system

schematic. Troubleshooting information for the diagnostic codes with a MID that is not 049

can be found in the service manual for that system.

ReferenceFor more information on the Vital Information Management System (VIMS),

refer to the Service Manual module Troubleshooting, "Using Vital InformationManagement System to Determine Diagnostic Codes".

Module Identifier (MID)

Diagnostics from other electronic control modules are shown on the monitoring system.

Other electronic control modules transfer this diagnostic information on the Cat Data Link

to the monitoring system.


18/28

The module identifier (MID) identifies the electronic control module that detected the fault.

Each electronic control module on the machine has a unique MID. Use the following chart

in order to match the MID for each diagnostic code to a specific electronic control module.

The chart for the Module Identifier (MID) is located on the Electrical System Schematic foryour machine. See the chart if the MID is not shown on the display of your machine. After

the operator determines the electronic control module that has detected the failure, see theservice manual module for that particular ECM for more troubleshooting information. Theservice manual for each ECM is part of the machine's Service Manual.

If the MID is for the VIMS ECM, use this service manual module. The MID for the VIMSECM is 049. If the MID is different use the appropriate module.

Detailed FMI Explanation

FMI 00 "Data Valid But Above Normal Operating Range"- Every electronic control

system sets a high limit for the expected operating range of the signal. The high limit

includes over range signals. This could be a high temperature. A sensor that is stilloperating but sending a signal above the expected limit will cause a FMI 00 to be stored.

Some of the possible causes of a FMI 00 are listed below.

The signal is above normal. The signal is shorted to the +battery circuit. The sensor needs to be calibrated.

This is an example of a sensor that needs calibration. A PWM signal that is at a duty cycleof 80 percent is a valid signal. If the PWM signal has a duty cycle of 81 percent the sensor

is still working, but the sensor signal is above the expected signal limits.

FMI 01 "Data Valid But Below Normal Operating Range"- Every electronic control

system sets a low limit for the expected operating range of the signal. The limit includes

signals that are under the lower limit. The low signal could be the oil pressure signal. The

sensor is still working but sending a signal below the expected limit will cause a FMI 01 tobe stored.


The signal is below the normal range. The timing is retarded.


21/28

This is an example of a PWM sensor. This sensor is not expected to generate a PWM signal

below a duty cycle of 5 percent with zero air pressure. If the sensor generates a signal with

a duty cycle of 4 percent when the engine is shutdown. The sensor is still working but

sending a signal below the expected limit will cause a FMI 01 to be stored.

FMI 02 "Data Erratic, Intermittent or Incorrect"- The signal from a component ispresent. The control that reads the diagnostic information can not read the signal properly.

The signal appears to be gone, unstable or invalid. The data can be correct or incorrect

intermittently. Also, this condition relates to communication between controls. This is an

example of communication between controls. When the monitoring system is looking forthe engine speed from the engine ECM over the Cat Data Link.

There is a failed connection. The signal is intermittent or erratic. The software has been changed. The signal is noisy. The signal is out of range.

FMI 03 "Voltage Above Normal or Shorted High"- The component or system voltageis higher than the limit. FMI 03 most often relates to a signal circuit.

Some of the components that could cause a FMI 03 are listed below.

The sensor or the switch has failed. The harness is damaged. The electronic control module has failed.


A sensor that has failed and the voltage output is high. Any wiring harness that has a sensor signal wire shorted to a high voltage. A high

voltage is any voltage that is greater than the sensor supply voltage.

A wiring harness that has an open circuit in the sensor signal wire will cause thecontrol to pull up. When this occurs the input circuit is pulled up to the supply

voltage.

A control that has failed will also cause a FMI 03. This is very unlikely.FMI 04 The Voltage is Below Normal or the Voltage is Shorted Low- The component

or system voltage is lower than the limit. FMI 04 most often relates to a signal circuit.

Some of the components that could cause a FMI 04 are listed below.

The sensor or the switch has failed. The harness is damaged. The electronic control has failed.


22/28


A sensor that has failed and the voltage output is low. Any wiring harness that has a sensor signal wire shorted to ground. A failed ECM will also cause a FMI 04. This is very unlikely.

FMI 05 Current Below Normal or Open Circuit- The current through the component or

the system is lower than the limit. FMI 05 is most often related to a driver circuit.


There is an open circuit or a poor harness connection. There is an open relay. There is a switch in the open position.

FMI 06 Current Above Normal or Grounded Circuit- The current through the

component or the system is higher than the limit. FMI 06 is most often related to a drivercircuit. This fault is very similar to FMI 04.


There is a short to ground in the harness connection. There is a shorted relay. A failed control will also cause a FMI "06". This is very unlikely.

FMI 07 Mechanical System Not Responding Properly- The control detects a signal thatis sent to a mechanical system and the response is not correct.


The component responds improperly. The component is stuck in a position. The component has failed. The engine is shut down. The machine is being used improperly.

FMI 08 Abnormal Frequency, Pulse Width or Period- This occurs when the signal isnot in the expected range. FMI 08 can also relate to a faulty sensor.


The harness connections are intermittent or poor. The engine misfired. The signal is noisy due to nearby interference. There are loose mechanical devices.


23/28

FMI 09 Abnormal Update- This relates to communications on the data link. FMI 09

occurs when a control is not able to get information from another control.


The control module is not communicating on the data link correctly.

The rate of data transmission is abnormal. The data link has failed. There is a mismatch of software.

FMI 10 Abnormal Rate of Change- This relates to a signal that changes too fast. The rate

of change is outside of the expected limit.

FMI 11 "Failure Mode Not Identifiable"- The control identifies more than one FMI as

being responsible for a single failure.


There is a mechanical failure. There is damage to multiple circuits.

FMI 12 Bad Device or Component- The electronic control sends a signal and the

electronic control expects a response. The control receives no response or the response isincorrect.


There is a failure of the electronic control.

There is a failure on the data link. There are one or more controls with mismatched software.

FMI 13 Out of Calibration- The electrical signal is not within limits for a specificmechanical condition.


Calibration is required. The data is out of range.

FMI 14, 15, and 20- These codes are not active.

FMI 16 Parameter Not Available- The control does not support the requested parameter.

FMI 17 Module Not Responding- The control does not respond to the request for data.

FMI 18 Sensor Supply Failure- The sensor power supply in the control has failed.


24/28

FMI 19 Condition Not Met- The conditions that are defined by the software were not

met.1 1 0

The ECM will assign a warning level to an active event code. Event codes are one of threelevels. The level is according to the severity of the abnormal condition. Each warning level

requires a specific response from the operator. The warning levels and the required operator

response are listed below.

25/28

Warning Level 1

Warning level 1 alerts the operator that a machine system requires attention. The operator

should check the involved system condition or the operator should perform maintenance onthe involved system at the earliest possible time.

Warning Level 2

Warning level 2 requires changing the operation of the machine or performing a

maintenance procedure. Failure to correct a problem that has caused this warning may

result in damage to the components that are involved in the system.

Warning Level 2S

Warning level 2S requires an immediate change in machine operation in order to avoid

possible damage to the system.

Warning Level 3

Warning level 3 requires an immediate safe shutdown of the machine in order to avoid

damage to the machine or injury to personnel around the machine. The problem that causedthe event must be corrected before machine operation can resume.

Indications and System Response

Caterpillar Electronic Technician (Cat ET) Service Tool

When an abnormal operating condition occurs, the status screen on the Cat ET indicates

that there is an active event.

Event codes are displayed on Cat ET in the following format:

EXXXX Description of the code

The "E" means that the code is an event code. The "XXXX" is a numeric identifier. The

numeric identifier is followed by a description of the code.

Active event codes are listed in ascending numerical order. The code with the lowestnumber is listed first. The active event code is removed from the list when the condition is

no longer present.

Logged Event Codes

Some event codes are logged in the ECM memory. Some event codes are active only. The

logged event codes are listed in chronological order. The most recent code is listed first.


26/28

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

The service technician manually clears the code. The code does not reoccur for 1000 hours. A new code is logged and there are already ten logged codes in memory. In this case, the

oldest logged code is cleared.

Note: Always clear logged event codes after investigating and correcting the problem

which generated the code.

List of Event Codes

The following table lists event codes and the recommended responses. Use the Cat ET

service tool in order to determine the event codes that are active or logged.

Synchronized clock

notification ofmanual synch

required

In a PL321 system using sync-clock and Product Link is not

the master ECM, the Product Link module will automatically

sync to the master ECM hours if the difference is not greater

than 50 hours. If the difference is greater than 50 hours, a

diagnostic will be generated in Cat ET that indicates that a

manual sync is required. In that instance, sync the hours. In

Cat ET, use "Service/Synchronize Service Meter Hours".

Inclusion Geo-

Fencing boundary

violated

Inclusive Geo-Fence sets up a "virtual fence" around a work

site. Once Inclusive Geo-Fence is activated, a report is

generated if the machine leaves the work site area. No repair

or service is required.

21322

Exclusion Geo-

Fencing boundary

violated

Exclusive Geo-Fence sets up a "virtual fence" around areas

that the machine is not allowed to enter. A report is

generated if a machine enters a restricted area. No repair or

service is required.

Time-Fencing

boundary violated

Time Based Fence allows the owner of a machine to choose

the time that a machine can be operated. A report is

generated if the machine is operated outside of the time that

is set for machine operation. No repair or service is required.

Switched Sensor

#1 trip condition is

activated

The Product Link PL300 has four additional inputs that can be

configured in order to monitor switches on the machine.

These inputs can be configured by using Caterpillar Electronic

Technician (Cat ET service tool). Troubleshoot input as setup

by the dealer.
