Reverse Lamp Control

The RFA module controls the reverse lamps whenever the vehicle transaxle is in reverse with the ignition ON. The RFA module monitors the output from the Powertrain Control Module (PCM) that contains the state of the transaxle. When reverse is detected, the RFA module activates the PERMLIGHT output and activates the reverse lamps.
