Cause

Due to variability in tolerance stack up, in some cases the NIU (or TCU) latch might not properly engage the activation switch, which prevents the NIU (or TCU) from powering on.

Solution

Reseating the NIU (or TCU), while taking care to properly engage the latch, should resolve the situation and power on the NIU (or TCU) as intended.
In some cases, a replacement module is required, as the activation switch may have gotten damaged or the latch is too loose to ensure a proper connection.
