FUNCTION CHECK





FREEZE FRAME DATA

NOTE:
^ Data stored at the time of trouble occurrence is shown on display.
^ Each time a trouble occurs, the latest information is stored in the freeze frame data in memory.
^ If a freeze frame data is not properly stored in memory (due to a drop in VDCCM power supply, etc.), a DTC suffixed with a question mark "?" appears on the Subaru Select Monitor display. This shows it may be an unreliable reading.








PARAMETER SELECTION

CAUTION:
^ Subaru Select Monitor is required for parameter selection.
^ This function can be used for the replacement VDCCM&H/U and VDCCM.

NOTE:
^ When a VDCCM is replaced with a replacement use this function to select and register parameters to the VDCCM.
^ For confirmation of applied models, refer to the "Model number plate" attached to the vehicles.
^ If a wrong applied model is written, it can be rewritten.
^ When no data is registered, ABS/EBD/VDC warning light illuminates and the DTC "Parameter selection error" is detected.
