Normal Operation
On vehicles equipped with remote keyless entry (RKE), when any door is opened, the vehicle security module sends an interior lamps ON signal to the
instrument cluster through UART based protocol (UBP) circuit 1906 (PK). When the instrument cluster receives the interior lamps ON request from
the vehicle security module, the instrument cluster will illuminate the puddle lamps by sending voltage to the puddle lamps through circuit 53
(BK/LB). Ground for the puddle lamps is provided through circuit 57 (BK).
