caution
  • When the diagnosis code No.B1159, B1160, B1164, or B1165 is set, be sure to diagnose the CAN bus line.
  • Before replacing ECU, ensure that the communication circuit is normal.

DIAGNOSTIC FUNCTION



  • OSS-ECU sets the diagnosis code No.B1159 when the chassis number is not written to OSS-ECU, and the diagnosis code No.B1160 when the key code is not written.
    note When OSS-ECU is new, the diagnosis codes No.B1159 and No.B1160 are set simultaneously.
  • OSS-ECU sets the diagnosis code No.B1164 when the chassis number is not written to the electric steering lock, and the diagnosis code No.B1165 when the key code is not written.
    note When the electric steering lock is new, the diagnosis codes No.B1164 and No.B1165 are set simultaneously.
