ELECTRICAL SYSTEM

System Description/RHD Models
The cornering lamp operation is controlled by the lighting switch which is built into the combination switch
and cornering lamp relay unit.
Power is supplied at all times
+to lighting switch terminal
V11
+through 10A fuse [No.15, located in the fuse block (J/B)].
Lighting operation by lighting switch
When lighting switch is in 1ST (or 2ND) position, power is supplied
+to cornering lamp relay unit terminal
V3
+through lighting switch terminalV12.
With the ignition switch in the ON or START position, power is supplied to cornering lamp relay unit termi-
nal
V2
+through 7.5A fuse [No.11, located in the fuse block (J/B)].
RH turn
When the turn signal lever is moved to the RH position, ground is supplied
+to cornering lamp relay unit terminal
V6
+through turn signal lamp switch terminalsV2andV1
+through body groundsE25andE40.
Power is supplied
+from terminal
V5of the cornering lamp relay unit
+to front combination lamp RH terminal
V3.
Ground is supplied to terminal
V4of front combination lamp RH through body groundsE25andE40.
The RH cornering lamp illuminates until the turn signal lever returns to NEUTRAL position.
LH turn
When the turn signal lever is moved to the LH position, ground is supplied
+to cornering lamp relay unit terminal
V8
+through turn signal lamp switch terminalsV3andV1
+through body groundsE25andE40.
Power is supplied
+from terminal
V10of the cornering lamp relay unit
+to front combination lamp LH terminal
V3.
Ground is supplied to terminal
V4of front combination lamp LH through body groundsE25andE40.
The LH cornering lamp illuminates until the turn signal lever returns to NEUTRAL position.
