HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and notes
given in section BR of the repair manual for the relevant model year when handling brake system parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC sys-
tem.
2. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance and
vibration resistance of the vehicle. After installing components in the sections listed in the table below,
perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of the
body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions giv-
en in the repair manual for the relevant model during alignment and section DI of this manual.
Component to be aligned
Front Wheels
Rear Wheels
3. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during han-
dling.
D Before repairing the body panels, remove their components or apply protective covers over the compo-
nents.
D Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool tip
or blade to prevent damaging the components and the body paint.
D Before removing components from the outer surface of the body, attach protective tape to the body to
ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.
D Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.
4. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.
D Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.
D Do not expose the ECUs to ambient temperatures above 80_C (176_F).
NOTICE: If it is possible the ambient temperature may reach 80_C (176_F) or more, remove the
ECUs from the vehicle before starting work.
D Be careful not to drop the ECUs and not to apply physical shocks to them.
