REGISTRATION WHEN REPLACING OSS-ECU AND ELECTRIC STEERING LOCK


caution
  • When KOS-ECU is replaced, all the registrations that need to be performed at KOS-ECU replacement must be completed before the registration of OSS-ECU and electric steering lock.
  • Be sure to check that the diagnosis code No.B1157 OSS EEPROM error and No.B1155 ESL EEPROM error are not set. If the diagnosis code No.B1157 "OSS EEPROM error" and No.B1155 "ESL EEPROM error" are set, the chassis number cannot be stored in memory even when it is written. Therefore, when these diagnosis codes are set, be sure to carry out the troubleshooting first to repair the trouble, and then write the chassis number to OSS-ECU or electric steering lock.

CHASSIS NUMBER REGISTRATION PROCEDURE


note Regardless of which of OSS-ECU or electric steering lock is replaced, the registration can be performed by executing the same menu selection. (Even when both OSS-ECU and electric steering lock were replaced as a set, they can be registered by performing the registration process only once.)

note The engine switch operation is necessary because the M.U.T.-III sets the forced power supply output to IG-ON by internal processing after the chassis number writing is executed.
