High Beam/Flash-to-Pass Operation

With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives input signal 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 signal is communicated to the IPDM E/R and the combination meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay coil, which when energized, directs power

• through 10A fuse (No. 34, located in IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 6, and
• through 10A fuse (No. 35, located in IPDM E/R)
• through IPDM E/R terminal 55
• to front combination lamp LH terminal 6.

Ground is supplied

• to front combination lamp RH terminal 5
• through grounds E9, E15 (all models) and E24 (with MR20DE),
• to front combination lamp LH terminal 5 via
• daytime light relay 1 terminals 3 and 4
• through grounds E9, E15 (all models) and E24 (with MR20DE).

With power and ground supplied, the high beam headlamps illuminate.

The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
