Light Check Module III (LCM III) (E38, E39, E53 from 9/98): Notes

The light check module LCM was redesigned as of 9/98 production. It is identified as the LCM III.

The module itself has been redesigned with new semi-conductor final stages that produce less heat in operation. This has allowed for the elimination of the protruding heat sink found on the previous LCM.

The total scope of function and features has been expanded to improve the comfort and safety for the driver and passengers of the vehicle. Feature and functional changes to the LCM III include:

• Replacement lighting for the parking lights.
• Limiting of output voltage to the lamps.
• Follow Me Home (delayed exit) lighting.
