Engine

D160/D161/D170 models do not support "uploading/downloading" functions, that are usually used in order to save the data stored in the BICU NVRAM out to external media for back-up before memory clearing. So if you need to make a back-up of the data, do the following steps.

1. Print out all SMCs.
2. Prepare a new NV-RAM
3. Remove the original NV-RAM and install the new NV-RAM that you just prepared.
4. Turn on the machine. All engine SP data will be overwritten to the default values from the new NVRAM (this does exactly the same as executing the engine memory clear in SP mode)
5. Refer the SMC list you printed in step 1 and input all data manually.
6. Now you have two NV-RAMs with the same settings. Keep one of these as a backup.

Before you change the NVRAM for uploading, do SP5-990-001 (SMC Print). You will need this engine data to restore the values after replacing the NV-RAM.

After replacing the NVRAM, specify the serial number and destination code of the machine.
Note:
• Installing a new NV-RAM initializes the engine information in the NVRAM.

Controller

There is no removable NV-RAM on the CTL board. When the controller board is replaced, it is necessary to re-enter the information manually.
