Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Courtesy Lamp Relay

Range: ON/OFF
The courtesy lamp relay output refers to the commanded state of the courtesy lamp relay coil. ON displays when the BCM commands the courtesy lamp relay coil to turn ON. This allows the relay to power up the courtesy lamps, and causes the courtesy lamps to turn ON. OFF displays when the BCM does not command the courtesy lamp relay coil to turn ON. This causes the courtesy lamps to be kept OFF.
