TSB's

Nissan MIL

This TSB applies to all Nissan vehicles equipped with a Key Slot for an Intelligent Key. DTC B2190 (NATS ANTENNA AMP) can be stored for the following reasons:

  1. Something other than an Intelligent Key is inserted into the Key Slot.
  2. An Intelligent Key issue.
  3. A wiring issue between the Key Slot and the BCM.
  4. A Key Slot issue.

If DTC B2190 is stored due to 1 or 2 above, it will not erase, or go to “PAST,” until a known good registered Intelligent Key is inserted into the Key Slot. For DTC diagnosis, first perform the service manual DTC Confirmation procedure.
