TRANSMISSION AR 4897275 - Caterpillar

Warning Levels
The ECM will assign one of three warnings levels to an active event code according to the severity of the abnormal system condition. Each warning level requires a specific response from the operator. The warning levels and required operator response are listed below.Level 1
An active warning level 1 event alerts the operator that a machine system could require attention. Level 1 events are logged, not displayed. If a Level 1 event is repeatedly activated, investigate the possible cause of the problem at the first opportunity. Check the involved system condition or perform maintenance on the involved system.Level 2
An active warning level 2 event can require a change in the operation of the machine to correct a problem. A warning level 2 event can indicate the need for a maintenance procedure. A level 2 warning that remains active or is repeatedly activated should be investigated at the earliest opportunity. Failure to correct the problem may result in the problem becoming more severe or possible damage to machine system components.Level 3
An active warning level 3 event requires an "Immediate Safe Engine Shutdown" by the operator to avoid possible damage to a machine system. Generally, a warning level 3 event will cause the ECM to disable operation of the involved system. The cause of the active event must be reset or resolved before the system can resume normal operation.Portions of this material are reprinted with permission from SAE J1939DA_201607© 2016 SAE International.

Event Codes for Transmission / Chassis ECU (MID 27)
Code (Level) Description Possible Cause or Recommended Response
E30 (2) High Transmission Oil Temperature Active: Transmission will latch to NEUTRAL if the torque converter outlet temperature is greater than 130° C (266° F) for 15 seconds
Inactive: When the torque converter outlet temperature drops below 100° C (212° F)
Note: The high temperature response mode is an optional feature that will put the transmission in a safe mode in a transmission overheating event. This feature is disabled by default and enabled through a programmable parameter in Cat ET
E155 (2) High Torque Converter Oil Temperature Active: Torque converter oil temperature is greater
