Prior to performing diagnostic work on the front heated seats as described in the diagnostic manual Body and Accessories, the test cable connector lock tab (arrow, Figure 1) must be modified.

In order to clear the divider in the seat heater control module (N25/5), carefully cut a notch 8 mm long x 2 mm wide in the locking tab of the test cable connector as shown (enlarged, Figure 1).
