Kode Pin ECM 9 Elctronic Control Module ) Hilux TGN 26

lksotomotif.com - ECM ( elekctronic control module ) adalah komponen yang mengontrol penuh sistem kinerja pada mesin secara elektronik. Gampangnya ECM adalah otak utama yang mengendalikan mesin sesuai dengan kondisi yang sedang terjadi. ECM berfungsi sangat penting pada setiap kendaraan. Tidak terkecuali pada Hilux berkode TGN 26 yang meluputi mesin berkode awal TR  yaitu 2TR-FE dengan kubikasi mesin 2.7L VVT-i bensin dengan penggerak 4WD.

Kerusakan ECM dapat menyebabkan kinerja mesin menjadi tidak maksimal atau bahkan mati. Kerusakan ECM harus segera ditangani dengan benar. Kerusakan komponen elektronik didalamnya akan diketahui jika sebelumnya dilakukan pemeriksaan dengan panduan yang benar.

Artikel ini menyediakan cara pemeriksaan ECM Toyota Hilux yang memudahkan mekanik untuk memeriksa secara umum sebelum memvonis ECM rusak.
