0A-20 General Information Caution for The Maintenance of Electrical Parts Battery Cable Disconnecting the battery cables Check that no foreign material or water has entered the inside of the connectors. Remove any foreign material or water that has entered the connector using an air brush, etc. If the material cannot be removed, replace them. Check that no foreign material is stuck to the terminals, and there is no corrosion or deformation. Remove any foreign material by cleaning with an air brush, or clean rag, etc. If the material cannot be removed by cleaning, or there is corrosion or deformation, replace them.
Gently pull the wires to check that no terminals are missing from the connector and there is no breakage in the terminal area. If a terminal is missing, reinsert it until it locks into place. If you find a disconnection, replace them. Insert the male connector into the same female connector, and check that there is no abnormality in the terminal contact pressure. If you find an abnormality, replace them. For waterproof connectors, check that there is no damage or foreign material stuck to the seal parts (wire seal of wiring, O-ring or waterproofing seal of connector, etc.) or seal area of the connector housing. Remove any foreign material by cleaning with an air brush, or clean rag, etc.
If the material cannot be removed by cleaning, or there is damage, replace them. 1. Turn all the switches "OFF". 2. Disconnect the battery ground cable (1). 3. Disconnect the battery plus cable (3). 4. Disconnect the battery cable (2). CAUTION: Make sure to disconnect the battery ground cable first. Disconnecting the plus cable first may cause a short circuit. 3 1 2 MFW70ASH000401 Connecting the battery cables CAUTION: Do not perform polishing that would remove the plating of the terminals, nor wash the inside of the connector. If there is dirt that requires washing, replace them.
Be careful when attaching the seal areas of waterproof connectors, as some have specific positions and directions they must be attached. Also do not attach them in a twisted state. Connect the battery cables in the reverse order of the disconnection procedure. CAUTION: Clean the area surrounding the battery terminal, and apply a thin layer of grease to the terminal to prevent corrosion. Connector Handling Requirements Regarding vehicle washing Visual inspection Even for electric parts that are installed outside the cab and are waterproofed, try to avoid exposing them directly to high pressure water when washing the vehicle (cover them with plastic sheets, etc.) as much as possible.
With the male and female connectors connected Gently pull the connector and check whether the connector becomes disconnected or partially disconnected, and that the lock is properly set. If a problem is found, reconnect the connectors. Check that there is no damage to the connector housing. If a problem is found, perform replacement. With the male and female connectors disconnected
