Scan Tool DataS7RS0B1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as re ference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the neutral position and A/T gear to the “Park” position and pull the parking brake fully. Also, if nothing
or “no load” is indicated, turn O FF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.

causes as battery explosion, battery
acid, or electrical burns.
– Damage to electronic components of either vehicle.
• Remove rings, watches, and other jewelry. Wear approved eye protection.
• Be careful so that metal tools or jumper cables do not contact positive battery
terminal (or metal in contact with it) and
any other metal on vehicle, because a
short circuit could occur. • Never expose battery to open flame or
electric spark. Batteries generate gas
which is flammable and explosive.
• Do not allow battery fluid to contact eyes, skin, fabrics, or painted surface as fluid is
a corrosive acid. Flush any contacted area
with water immediately and thoroughly.
• Batteries should always be kept out of reach of children.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
