Corrective Action
Engine
Shutdown
E 01
P1 Pressure Sensor abnormal.
Check harness connector at pressure sensor P1.
E 02
P2 Pressure Sensor abnormal.
Check harness connector at pressure sensor P2.
E 03
P3 Pressure Sensor abnormal.
Check harness connector at pressure sensor P3.
E 04
Discharge Air Temp. Sensor abnormal.
Check harness connector at discharge air temp sensor.
E 05
Fuel Level Sender abnormal.
Replace fuel sender.
E 06
Controller circuit board signal error "1".
Check harness connectors between circuit board (CU-40)
and display board (CM-40).
E 07
Controller circuit board signal error "2".
Check the harness connectors between circuit board
(CU-40) and display board (CM-40).
E 10
Engine Low Speed
Adjust using load.
E 11
Battery Charging abnormal.
Check fan belt. Adjust using load. Inspect charge relay
circuit for charging generator.
E 12
Emergency Stop device "1" signal input.
(Option)
L.oil.P
Engine Low oil pressure
Replenish engine oil.
H.co.t
High Engine Coolant Temperature.
Check coolant system for leaks and radiator for coolant
level.
E 14
Low Fuel Level. (Empty)
Refill fuel.
E 15
Engine controller processing time out error
Check DTC codes. Restart the engine.
E 16
Emergency Stop device "2" signal input.
(Option)
E 18
Engine CAN signal error.
Check the CAN wires between circuit board (CU-40) and
ECM.
E 20
High Discharge Air Temperature.
Check and clean oil cooler. Replenish compressor oil.
E 22
Discharge Air pressure abnormally high
Check and repair proportional solenoid valve.
E 23
Proportional Sol. V abnormally low current
Inspect the harness between proportional solenoid valve,
circuit board (CU-40), and ECM.
E 24
Proportional Sol. V over current.
E 97
Memory error.
Turn main switch OFF and ON again. If error code
remains, replace circuit board (CU-40).
E 99
Controller microprocessor WDT error.
Turn main switch OFF and ON again. If error code
remains, replace circuit board (CU-40).
(No engine
behavior
change)
A 10
Engine Air Filter clogging.
Check and clean air cleaner element.
A 21
Compressor Oil Filter clogging.
Replace compressor oil filter.
EMERGENCY STOP AND DIGITAL CONTROLLER DISPLAY
The engine will not start if an error is detected before starting. If an error is detected during operation, the engine will
be shutdown and the digital controller will display the error code and the error code LED will light. Error codes that are
displayed with an "E" are emergency shutdown codes. Error codes that are displayed with an "A" are alarm codes. Reference
Table 14 (next page) for engine sensor error DTC codes. Reference Table 13 below for a brief explanation of the engine
and air compressor error codes.
