caution | When replacing the ECU, always check that the communication circuit is normal. |
caution | To prevent damage to scan tool (M.U.T.-IIISE), always turn the power supply mode of the electric motor switch to the OFF before connecting or disconnecting scan tool (M.U.T.-IIISE). |

note | Because the conformity cannot be determined even when the digital tester is used to measure the voltage of SW2 line between the OSS-ECU connector and electric motor switch connector, be sure to use the oscilloscope. (Outputs the sawtooth waveform of 0 to 5 V with intervals of 10 ms.) |
