caution | When replacing the ECU, always check that the communication circuit is normal. |
note | If the fuse No.10 (10 A) is blown, there may be a short to ground between the fuse and KOS&OSS-ECU power supply. However, because the fuse No.10 is branched off, determine the root cause while referring to the Electrical Wiring Manual. |
