PARKING, LICENCE PLATE AND TAIL LAMPS OPERATION

When the combination switch (lighting and turn signal switch) is in 1ST position, BCM detects the LIGHTING
SWITCH 1ST POSITION ON. The BCM sends a parking light ON request via the CAN communication lines to
the IPDM E/R. The IPDM E/R then activates the tail lamp relay which sends power to the parking and instru-
ment illumination circuits. 

EXTERIOR LAMP BATTERY SAVER CONTROL

With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes unless the combination switch (lighting
and turn signal switch) position is changed. If the combination switch (lighting and turn signal switch) position
is changed, then the headlamps are turned off. 
This setting can be changed by CONSULT-III. Refer to 

BCS-22, "BATTERY SAVER : CONSULT-III Function

(BCM - BATTERY SAVER)"

System Description

INFOID:0000000005561508

TRAILER TAIL LAMP OPERATION

The trailer tail lamps are controlled by the trailer tow relay 1 located in the IPDM E/R. With the combination
switch (lighting and turn signal switch) in the 1st position, the BCM detects the LIGHTING SWITCH 1ST POSI-
TION ON. The BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The
IPDM E/R then activates the tail lamp relay which activates the trailer tow relay 1 and sends power to the
trailer connector.

TRAILER TURN SIGNAL LAMP OPERATION

The trailer turn signal lamps are controlled by the BCM. When the combination switch (lighting and turn signal
switch) is in the LH or RH position with the ignition switch ON, the combination switch (lighting and turn signal
switch) sends a signal to the BCM. The BCM detects the TURN RH or TURN LH ON request. The BCM sends
a control signal to the respective trailer turn relay which sends power to the trailer connector.

TRAILER HAZARD LAMP OPERATION

The trailer hazard lamps are controlled by the BCM. When the hazard switch is pressed, the BCM detects the
the hazard ON request. The BCM then sends a control signal to both trailer turn relays which sends power to
the trailer connector.

TRAILER BRAKE LAMP OPERATION

The trailer brake lamps are controlled by the BCM. When the brake pedal is depressed, the combination meter
receives a stop lamp switch signal from the stop lamp switch. The combination meter then sends the brake
signal to the BCM via the CAN communication lines. The BCM then sends a control signal to both trailer turn
relays which sends power to the trailer connector.
