FORCED POWER SUPPLY OUTPUT PROCEDURE

Required Special Tools:

- MB991958: Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: V.C.I.
- MB991827: M.U.T.-III USB Cable
- MB991910: M.U.T.-III Main Harness A





CAUTION:
To prevent damage to scan tool (MB991958), always turn the power supply mode of the engine switch to the OFF position before connecting or disconnecting scan tool (MB991958).

With OSS, the power supply cannot be turned ON until the certification communication with KOS and electrical steering lock is complete. However, using the scan tool MB991958, the power can be forced ON even when the certification communication with KOS and electrical steering lock is not completed. (However, locking/unlocking of the electrical steering lock is not performed.) Through this process, the error in certification with KOS or electrical steering lock can be distinguished from the malfunction in power supply. In addition, the process allows the CAN bus diagnosis as well as the reading of diagnosis code, belonging to systems other than OSS, to be performed.
