Removal and InstallationINFOID:0000000003793258
CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
 Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
 Be careful not to cut your hand on the heat insulator edge.

EXHAUST SYSTEM
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 When installing each mounting rubber, use silicon oil to avoid twisting.
 Temporarily tighten mounting nuts and bolts. Check each part for unusual interference, and then
tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear
and right/left directions.
InspectionINFOID:0000000003793263
INSPECTION AFTER INSTALLATION
 Check clearance between tail tube and rear bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

J P L I A 111 8 Z Z
Part Description
BCM Detects each switch condition by the combination switch reading function.
 Judges that the headlamp is turned ON according to the vehicle condition.
- Requests the headlamp relay (HI/LO) ON to IPDM E/R (with CAN communication).
- Requests the high beam indicator lamp ON to the combination meter (with CAN
communication).
IPDM E/RControls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch
(Lighting & turn signal switch)Refer to BCS-8, "
System Diagram".
Combination meter
(High beam indicator lamp)Turns the high beam indicator lamp ON according to the request from BCM (with CAN
communication).

AUTO LIGHT SYSTEM
 Turns the exterior lamp OFF with the ignition switch ACC or the light switch OFF.
*: The preset time is 45 seconds. The timer operating time can be set by CONSULT-III. Refer to EXL-28,
"HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)".
NOTE:
When any position other than the light switch AUTO is set, the auto light system function switches to the exte-
rior lamp battery saver function.
