Production Mode



Production mode
If the MOST control module is set to Production mode on, it is in low-current mode. This status is indicated by the message 'PROTECTED' on the display. The control module cannot function. If production mode is coded out, the control module is operational again following a restart (vehicle must be locked and secured).

The following options can be coded:
- Production mode off.
- Production mode on.
