LH Turn

When the turn signal switch (combination switch) is moved to the LH position, the BCM (body control module) receives left turn signal by combination switch reading function (Refer to COMBINATION SWITCH READING FUNCTION ).

• Through BCM (body control module) terminal 22
• To front turn signal lamp LH (part of the front combination lamp LH) terminal 2 (with xenon headlamp)
• To front turn signal lamp LH (part of the front combination lamp LH) terminal 1 (with halogen headlamp)
• To rear turn signal lamp LH (part of the rear combination lamp LH) terminal 2.

Ground is supplied to the front turn signal lamp LH (part of the front combination lamp LH) terminal 1 through grounds E17, E43 and F152 (with xenon headlamp).

Ground is supplied to the front turn signal lamp LH (part of the front combination lamp LH) terminal 4 through grounds E17, E43 and F152 (with halogen headlamp).

Ground is supplied to the rear turn signal lamp LH (part of the rear combination lamp LH) terminal 4 through grounds T14, B6, B5 and D105.

The BCM also supplies ground to unified meter and A/C amp terminals 1and 11 across the CAN communication lines. This input signal is processed by the unified meter control unit in the combination meter through the unified meter and A/C amp, which in turn supplies ground to the left turn signal indicator lamp.

With power and ground supplied, the BCM controls the flashing of the LH turn signal lamps.
