Daytime light relay circuit
Description
The bcm sends a daytime light request to the ipdm e/r via the can
communication lines. The power flows
through fuse 29 located in fuse block j/b to the daytime light relay coil. When
the ipdm e/r operates the daytime
light relay, power is sent to the daytime lamps.
