System Description

INFOID:0000000001523226

Control of the headlamp system operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 2nd position, the BCM (body control module) receives input
requesting the headlamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distri-
bution module engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM
E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to
the respective headlamps, which then illuminate.

When the lighting switch is in 2nd position, the BCM receives input requesting the headlamps to illuminate.
This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of the IPDM E/R
controls the headlamp low relay coil which supplies power to the low beam headlamps.

HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION

With the lighting switch in the 2nd position and placed in HIGH position, the BCM receives input requesting the
headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of the
combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R con-
trols the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) via the CAN communication lines and turns
the high beam indicator lamp ON.
