FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power
• through IPDM E/R terminal 36
• to front fog lamp RH terminal 1,
• through IPDM E/R terminal 37
• to front fog lamp LH terminal 1.
Ground is supplied
• to front fog lamp RH and LH terminals 2
• through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
CAN Communication System Description
INFOID:0000000001328329
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
