GRILL AS 4152793 - Caterpillar

(1) The active warning indications are marked with an X. (2) The possible result, if the operator takes no action. (3) The alarm is on continuously. (4) The alarm is on intermittently. Caterpillar Electronic Technician (Cat® ET)
When an abnormal operating condition occurs, the status screen on Cat® ET will indicate that there is an active event.Event codes are displayed on Cat® ET in the following format:EXXXX Description of the codeThe "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 lowest number 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.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.Troubleshooting
Perform the following steps to troubleshoot an event:
Obtain the following information from the operator:
The event and the time of the event
Determine the operating conditions of the engine 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.
Some of the events below can become active during normal system 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. ECM Event Code List
The following table lists the event codes that apply to the control system. The recommended response is listed. Use Cat® ET to determine if the event codes that are active or logged.
Table 2
Event Codes for the Implement ECM (MID 82)
Code (Level) Description Recommended Response/Possible Cause
E349 (1) Lift Linkage Movement Detected w/ no Command Given Activates when ECM detects a signal from the Tilt Linkage Position Sensor indicating tilt mechanism movement with no command from the operator tilt control.
Deactivates when ECM receives lift command signal (from lift lever / joystick sensor) and Lift Linkage Position Sensor indicates lift arm movement in the correct direction.
If the event is repeatedly activated, check the actuator linkage for the tilt position sensor. Ensure that the actuator linkage is tight and in good condition. Verify that there is no damage to the actuator or to the position sensor.
Check hydraulic system for seal leakage or problems with the main valve or the pilot valve. Run the "Lift Linkage Sensor Calibration" in Cat® ET.
