existing TCS Service Manual, Section 2:5, but
instead a supplement intended to be used in con-
junction with the Service Manual.

?;
To
assist in fault
diagnosis when working on the TRACTION CONTROL
SYSTEM fitted to Saab cars.
Goal -"FIX IT RIGHT FIRST TIME".
You are expected to have a reasonable understanding of how the Traction
Control System works. If you do not, please refer to Service Manual for
an explanation of system operation .
You should take the necessary precautions in your work at all times to
avoid accidents and injury, particularly observing important HEALTH and
SAFETY regulations.
The TIM should be well looked after and regularly updated. Take it with
you when you go to the TRAINING SCHOOL.

2 TCS Information Manual (TIM)
General rules for fault diagnosis
Many components that our tests show to be in per-
fect condition are still being replaced.
To avoid the replacement of components in perfect
condition, the following steps should always be
taken.
• If diagnostic trouble codes are obtained, check
the operation of the relevant components or sys-
tem using a Scan Tool as described in Service
Manual 2:5 and/or in this manual. All importers
have been supplied with this Manual. It contains
selected information explaining how to diagnose
faults and rectify them.
• Check the wiring and connectors for continuity,
poor contact, damaged connecting pins, etc. Use
"KONTAKT 61 part No. 45-30 04 520, which is
an aerosol contact cleaner lubricant with good
long-term reliability specially developed for elec-
trical connectors and switches.
• When changing several components at the same
time, make sure that the components really are
defective before fitting replacements.

Testing procedures 7
READ THE DTCs
Carry out fault diagnosis on all systems from
both the green and black data link connectors
and make a note of all the diagnostic trouble
codes.
CLEAR THE DTCs
Clear the trouble codes in all systems but do not
recalibrate any systems at this time.
Power Off test
It has been found that DTCs.
can be generated in
other systems on .
·
models during the ETS
system Power-Off test (performed each time the
ignition is switched off) while the scan tool is still
connected. On all models it is therefore advisable
to terminate scan tool communication before
switching OFF the ignition.
ENTERCOMMANDCODES
Enter command codes according to the DTCs
obtained as described above. Refer to "Com-
mand Codes" on page 18.
