1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -

4) Operating Process By Power Supply
(1) Rear wiper relay
(2) Rear fog lamp relay
The rear wiper motor relay is turned on when the rear wiper switch is turned on with the ignition key ON.
This relay is turned off when the rear wiper switch is turned off.
The power is supplied to the ICM no. B6 connector through the SB4 and no. 39.
The power for the rear fog lamp relay is supplied through the memory fuse in the engine compartment
CE box and fuse no. 52 in the interior IP box. This relay is controlled (ON/OFF) by the relay operation
signal which is connected to the no. A11 of the BCM.
The rear fog lamp is turned on when the rear fog lamp switch is turned on with the headlamp turned
on (i.e. IGN2 switch ON).
Turning on the rear fog lamp switch again when the relay is activated turns off the fog lamp.
The rear fog lamps do not come ON when the IGN2 switch is turned to OFF position or the light
switch is OFF.
The rear fog lamp should not automatically come on again if it has been turned off by any methods
other than the rear fog lamp switch. 1.

(7) Shift lock relay
The shift lock relay is used in the models with A/T and receives power through the SB2 and fuse no. 31
in the interior fuse box with the IGN1 turned ON. If the operating conditions are met (stop lamp switch
ON), the battery power is supplied to the ICM terminal no. C1. If the gear mode conditions are met, the
relay is operated by the signals from the terminal no. 10 of the gear selector lever.
(8) Power outlet relay
The power for the power outlet relay is supplied to the ICM terminal no. B10 through the battery SB1
and fuse no. 46 in the interior fuse box. The relay is earthed through the fuse no. 47 in the interior fuse
box and then ICM terminals no. B2 and no. B12 when the ignition key is turned to ACC.
