HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU in the
IPDM E/R controls the headlamp low relay coil, which when energized, directs power


to 15A fuse [No. 76, located in IPDM E/R]


through IPDM E/R terminal 20


to headlamp RH terminal 3, and


to 15A fuse [No. 86, located in IPDM E/R]


through IPDM E/R terminal 30


to headlamp LH terminal 3.
Ground is supplied


to headlamp RH terminal 4


through grounds E17 and E43


to headlamp LH terminal 4


through grounds E17 and E43.
With power and ground supplied, low beam headlamps illuminate

Use a multimeter to test
