Service Information
General Safety
● Connect the same color wires together. Connect couplers carrying the same color and the same number of
pins together.
● All couplers are equipped with tabs which can be locked. Remove these locks prior to disassembling; and
insert these tabs all the way until locked when assembling.
● Carry out continuity test on circuits or parts to diagnose electric systems. The continuity test on normal
parts can be carried out without removing the parts from the vehicle. Simply disconnect the wires and
connect a continuity tester or an ohmmeter to the coupler terminals or connectors.
● The continuity test is conducted to check if electric power is connected between 2 terminals. If there is coil
resistance within circuits, or to check the large resistance resulting form the connector corrosion, an
ohmmeter is required to check the circuit resistance value.
