Exterior Lighting Module: Description and Operation

Light Module (LM)

The Light Module (LM) controls and monitors all of the exterior lights as well as controlling the LWR headlight aiming function. It is also the dimmer master for instrument and panel lighting and includes emergency functions in case of malfunction.

The Light Module is connected to the K-CAN-S for communication with the Rain Light Sensor (RLS) and the rest of the vehicle including diagnosis.

The LM has one 76 pin connector (X12). The case is ventilated to dissipate heat from the final stage semi-conductors.




The light module is located below the drivers side of the instrument panel, to the left of the steering column and behind the sheet metal support for the dashboard.

To remove the module it is not necessary to remove the drivers side knee airbag.
