HEADLAMP SYSTEM : System Description
LOW BEAM OPERATION
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 across
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 f
eature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM
E/R across 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) through the CAN communication lines and
turns the high beam indicator lamp ON.
