Hi, all.
Recently, another owner contacted me with EPS failure code #22.
His EPS controller was the old version of parts no. 39980-SL0-023 which was equipped with standard spec relays that would fail after lots of EPS usage by overcooking the relays.
Honda modified the relay spec from 39980-SL0-305 onwards and it replaced one of the two relays to the high current capacity spec to overcome the common failure mode of error code #22.
As it was possible to get hold of the high current capacity relays from US this time, it was agreed to drill the extra holes to the existing board.
The standard spec on the left and the high current capacity one on the right. As you can see, the switched terminals have 3 pins compared to just one on the standard spec.
Although Honda replaced just one of the relay with the new spec, it was decided to replace both of them to the high current capacity ones for this owner. This means that I had to drill extra 8 holes on the existing board.
After the preparation, new holes were drilled. Quite delicate touch was required....
After creating the new holes, the coating was removed to enable the soldering joints around the 3 pins terminals. As new holes won't be a through hole joint, it is important to create strong connection each other.
Installed the new relays and quick test was carried out to confirm no short circuit after the modifications.
The owner installed the modified EPS controller and happy with the result.
Hope he will enjoy the EPS.
Regards,
Kaz
