It has been found in the field that the soldered section of the FASTON terminal on the 
Fusing Interface PWB was cracked, causing a malfunction (H4, etc.). It has also been found 
that in certain circumstances ignition may occur. This is to inform you of the 
countermeasures taken to solve this problem. 
To prevent this problem from occurring, 
replace the Fusing Interface PWB immediately.
AR-250/280/285/286/287/335/336/337/405/407/505/507 
 
The soldered section is cracked due to stress produced when the tab terminal is 
connected/disconnected. As a result, imperfect contact occurs at the section due to thermal 
stress produced during operation, causing a malfunction. 
 
To reinforce the PWB, the material of the Interface harness PWB is changed to a glass fiber 
filled double-sided PWB, and soldering is performed on the front and rear sides by making a 
through hole.
