SOFTWARE GP- 3832681 - Caterpillar

The crank terminate relay is set and the engine has been running for at least 30 seconds. The differential between the temperature of the engine oil and the temperature of the engine coolant has exceeded the trip point. Also, the delay time has expired. There are no active codes for the sensors for the engine oil temperature and the engine coolant.System Response:The following event codes are logged according to the trip points for the temperature differential:
E337 (1) High Engine Oil to Engine Coolant Diff Temp (warning)
E337 (3) High Engine Oil to Engine Coolant Diff Temp (shutdown)If a warning is activated, the alarm output is activated.If a shutdown is activated, the shutdown output is activated.Possible Performance Effect:If a warning is generated, the engine operation is not immediately affected.The engine will be shut down if the trip point for the shutdown is exceeded.Troubleshooting:Test Step 1. Refer to Troubleshooting, "Jacket Water to Engine Oil Differential Temperature (Low)".Results:
OK - STOP
