Forced Power Supply Output Procedure: Notes
Required Special Tools:
- MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
- MB992745: V.C.I.-Lite main harness A (for vehicles with CAN communication)
- MB992747: V.C.I.-Lite USB cable short
- MB992748: V.C.I.-Lite USB cable long
- MB991958: Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: Vehicles Communication Interface (V.C.I.)
- MB991827: M.U.T.-III USB Cable
- MB991910: M.U.T.-III Main Harness A (Vehicles with CAN communication system)
CAUTION:
To prevent damage to scan tool (M.U.T-III), always turn the power supply mode of the engine switch to the "OFF" position before connecting or disconnecting scan tool (M.U.T-III).
With OSS, the power supply cannot be turned "ON" until the certification communication with KOS is complete. However, using the scan tool, the power can be forced "ON" even when the certification communication with KOS is not completed. Through this process, the error in certification with KOS can be distinguished from the malfunction in power supply. In addition, the process allows the CAN bus diagnosis as well as the reading of diagnostic trouble code, belonging to systems other than OSS, to be performed.
