Error code data

Data Description Explanation

0 Operations normal

1 Back-up data check error The control data has been destroyed or written

wrongly

2 RAM read/write error Problem with the system RAM

3 System structure error The system structure has been changed

4 Internal communications error Abnormality in the internal communications

5 A/D converter error Problem with the A/D converter

6 Adjustment data error The adjustment data has been written wrongly

Presumed causes of occurrence:

a) When errors 1, 2 or 5 have occurred, a breakdown in the RAM, ROM or A/D converter should be

suspected.

b) Error 3 occurs when the module structure is different from the initial structure. An example would

be if a module is replaced by a different model of module. In this situation, replace with the same

model of module. Further, this error will also occur when module initialize has not been carried

out after changing the module structure.

c) Error 4 occurs in the situation where a module is removed while the power is still on, etc.

d) If errors 5 or 6 occur, there is a possibility that too much noise, surge or strong shock has been

applied to the control unit.
