WARNING!
Handling of Rear End Door Balancer
(Damper)
• Handle balancer carefully. Do not scar or scratch exposed surface of its piston rod,
and never allow any paint or oil to stick to
its surface.
• Do not turn piston rod with balancer fully extended.
• Do not disassemble balancer (1) because its cylinder is filled with gas.
Discarding of Rear End Door Balancer
(Damper)
• The gas itself in balancer is harmless but it may issue out of the hole together with
chips generated by th e drill (2). Therefore,
be sure to wear goggle when drilling.
• Using a 2 to 3 mm (0.08 to 0.12 in.) drill (2),
make a hole to remove gas inside as
shown before discarding.

Installation

Immobilizer Indicator Lamp Remains ON after Engine StartsS7RS0BA304007
Wiring Diagram
Refer to “Immobilizer Control S ystem Wiring Circuit Diagram”.
Circuit Description
When the ignition switch is turned ON, ECM read the code by the coil antenna from ignition key. Then if the code in
transponder in the key match with the one registered with ECM, transmits indication ON signal of immobilizer indicator
lamp to combination meter in order to turn immobilizer indicator lamp on. And then, combination meter turns
immobilizer indicator lamp on. When th e engine starts to run and no malfunction is detected in the system, ECM
transmits immobilizer indicator lamp indication O FF signal to combination meter in order to turn immobilizer indicator
lamp off. And then, comb ination meter turns immobilizer indicator lamp off, but if a malfunction was or is detected,
immobilizer indicator lamp is flashes ON and OF F, when ignition switch turn to ON position.
