System Description
INFOID:0000000005146617
The headlamp aiming system (manual) controls the headlamp light axis height according to input from the
headlamp aiming switch. The variable internal resistance of the headlamp aiming switch controls the signal
ground of the headlamp aiming motors located on the front combination lamp LH and RH.

INFOID:0000000005369879
System Description
INFOID:0000000005369880
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The combina-
tion switch (lighting and turn signal switch) signal to the BCM is monitored with the BCM combination switch
reading function. When the fog lamps are turned ON with the combination switch (lighting and turn signal
switch), the BCM sends a front fog lamp request signal via CAN communication lines to the IPDM E/R. The
IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.

FRONT FOG LAMP OPERATION
When the combination switch (lighting and turn signal switch) is in front fog lamp ON position and also in 1ST
or 2ND position or AUTO position (headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP1, 2
ON or the AUTO LIGHT ON. The BCM sends a front fog lamp request ON signal via the CAN communication
lines to the IPDM E/R. The IPDM E/R then turns ON the front fog lamp relay sending power to the front fog
lamps.

System Description

TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal switch) is in LH or RH position with the ignition switch in
ON position, the BCM detects the TURN RH or TURN LH ON request. The BCM outputs the flasher signal to
the respective turn signal lamp. The BCM also sends a turn indicator signal ON request via the CAN commu-
nication lines to the combination meter. The combination meter then activates the appropriate turn signal indi-
cator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazard indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combination meter then activates the hazard indicator and audible
buzzer.
REMOTE KEYLESS ENTRY OPERATION
The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard
lamps.
