ECU MITSUBISHI LANCER EVOLUTION 2007 Service Repair Manual

WARNING REGARDING SERVICING OF SUPPLEMENTAL
RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLE
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component,
can lead to personal injury or death to service personnel (from inadvertent firing of the air
bag) or to the driver and passenger (from rendering the SRS inoperative).
(2) The SRS components should not be subjected to temperature of 93_C or more. So, remove
the SRS-ECU, driver’s and front passenger’s air bag modules and clock spring before drying
or baking the vehicle after painting.
(3) Service or maintenance of any SRS component or SRS-related component must be performed
only at an authorized MITSUBISHI dealer.
(4) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP
52B - Supplemental Restraint System (SRS), before beginning any service or maintenance
of any SRS component or any SRS-related component.
NOTE
Section titles with asterisks (*) in the table of contents in each group indicate operations requiring warnings.

BODY DIMENSIONS -Body Dimensions and Measurement MethodsB-2
BODY DIMENSIONS AND
MEASUREMENT METHODS
1. Type A (projected dimensions)
Indicates the dimension when a measurement location
is projected onto a plane.
The difference in height of the measurement points should
be taken into consideration when measuring.
2. Type B (actual-measurement dimensions)
Indicates the actual distance between the measurement
points.
Measure using a tracking gauge or a measuring tape,
etc.
NOTE
DMake the lengths of the tracking gauge probes the
same (A=A’).
DDo not bend or twist the measuring tape.
3. Insert the tracking gauge probes securely into the
measurement holes
4. When the standard dimensions in the illustration are
enclosed by, this indicates that the symmetrical left and
right positions have the same dimensions.
5. When using a notch for dimension measurement, set
the measuring point at the centre of the notch.
6. When measuring the suspension mounting arm, or link
mounting position, use the suspension mounting bolt,
etc..
7. The body centre points are shown for the purpose of
checking the position of the left and right symmetry
locations.Height
