Diesel particulate filters (DPF) require routine cleaning to remove ash that builds up over time. Most vehicles using a DPF system will have an on-board filter service monitor to indicate the filter condition and guide your filter cleaning schedule.
In ancient times the islands formed an independent kingdom. Chinese and Japanese sovereignty were successively forced on the archipelago from the 14th to the 19th century, and in 1879 the Ryukyus became an integral part of Japan. After the defeat of Japan (1945) in World War II, the United States took control of the islands.
Also, in Chinaâs view, Japan obtained control over the islands as a result of a treaty that ended the First Sino-Japanese War in 1895. Japan took control of the islands, via the treaty, when it forced China, which lost the war, to cede Taiwan to Japanâand in Chinaâs view, the islands are part of Taiwan. When Taiwan was returned to China after World War II, the islands should have gone back with it.
