Code :

Code: E1 00
Description: IMC communication trouble. An abnormality occurs in communication between the CPU and the IMC.
Causes: IMC – CPU signal line abnormality IMC Memory defect/data abnormality
Remedy: Replace the MCU PWB with new one.

Code: E1 13
Description: An abnormality occurs in the IMC flash ROM.
Causes: IMC abnormality
Remedy: Replace the MCU PWB with a new one. If downloading of the program is abnormally terminated, it may cause an error. Download the program again to avoid this.

Code: E1 16
Description: IMC DIMM memory read/write check error. An installation error occurs in the IMC memory module. An error occurs during access to the IMC memory.
Causes: Improper installation of the IMC memory module. IMC memory module abnormality IMC memory contact abnormality IMC abnormality.
Remedy: Check installation of the memory module. Replace the memory module. Replace the MCU PWB with a new one.

Code: E1 81
Description: A parity error occurs in communication between the CPU and the IMC.
Causes: IMC memory defect/data abnormality
Remedy: Check the memory of the IMC. Replace the MCU PWB with new one.

Code: E1 82
Description: IMC communication interface error (Overrun). An overrun error occurs in communication between the CPU and the IMC.
Causes: IMC memory defect/data abnormality.
Remedy: Check the memory of the IMC. Replace the MCU PWB with new one.

Code: E1 84
Description: IMC communication interface error (Framing). A framing error occurs in communication between the CPU and the IMC.
Causes: IMC memory defect/data abnormality.
Remedy: Check the memory of the IMC.

Code: E7 02
Description: LSU trouble. The BD signal from the LSU cannot be detected in a certain cycle. (Always OFF or always ON)
Causes: LSU connector or LSU harness defect or disconnection Polygon motor rotation abnormality Laser beams are not generated. MCU PWB abnormality.
Remedy: Check connection of the LSU connector. Execute TC 61-03 to check the LSU operations. Check that the polygon motor rotates normally. Check that the laser emitting diode generates laser beams. Replace the LSU unit. Replace the MCU PWB.
