caution | Before replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal. |
note | Because the conformity cannot be determined even when the digital tester is used to measure the voltage of PDSW line between the selector lever assembly connector and KOS&OSS-ECU connector, be sure to use the oscilloscope (Outputs the sawtooth waveform of 0 to 5 volts with intervals of 10 ms.). |
