• to rear combination lamp LH terminal 1
• through grounds B7 and B19.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power
• through BCM terminal 61
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 (all models) and D402 (with hatchback).
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.

Ground is supplied
• to BCM terminal 67 and
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61.
When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power
• through BCM terminal 60
• to front combination lamp LH terminal 4 and
• to rear combination lamp LH terminal 6,
• through BCM terminal 61
• to front turn signal lamp RH terminal 4 and
• to rear combination lamp RH terminal 6.
Ground is supplied
