3. CONDITIONS FOR COMPLETION OF TCS
SEQUENCE CONTROL
When the following conditions develop, the TCS sequence
control stops and ABS and TCS warning lights come on
while the ABS and TCS function will then stop. The brake
system functions as a conventional brake system.
1) When the speed of at least one wheel reaches 10 km/h
(6 MPH).
2) When terminal No. 4 is separated from ground. (When
select monitor is not used.)
3) When the brake pedal is depressed during sequence
control and the braking lamp switch is set to ON.
4) When TCS OFF switch is released. (When select moni-
tor is not used.)
5) After completion of the TCS sequence control.
6) When output signal to break TCS control is emitted from
ECM.
7) When malfunction is detected.
NOTE:
When malfunction has been detected and the TCS
sequence control operation has stopped, the trouble codes
are stored in memory.

4. CONDITIONS FOR TCS SEQUENCE CONTROL
B4M0642A
NOTE:
When select monitor is used, control operation starts at
point A. It is not required to operate TCS OFF switch for
starting control operation. The patterns from IGN key ON
to point A show operation is started by diagnosis connec-
tor.

A: REMOVAL
1) Disconnect ground cable from battery.
2) Remove air intake duct from engine compartment to
facilitate removal of ABSCM&H/U.
3) Use an air-gun to get rid of water around the
ABSCM&H/U.
CAUTION:
The contact will be insufficient if the terminal gets wet.
B4M1224A
4) Pull on the lock of the ABSCM&H/U connector to
remove it.
5) Disconnect connector from ABSCM&H/U.
CAUTION:
Be careful not to let water or other foreign matter con-
tact the ABSCM&H/U terminal.
6) Unlock cable clip.
7) Disconnect brake pipes from ABSCM&H/U.
CAUTION:
Wrap brake pipes with vinyl bag to avoid spilling brake
fluid on vehicle body.
B4M1222
8) Remove ABSCM&H/U from engine compartment.
CAUTION:
ABSCM&H/U cannot be disassembled. Do not
attempt to loosen bolts and nuts.
Do not drop or bump ABSCM&H/U.
Do not turn the ABSCM&H/U upside down or place
it on its side.
Be careful to prevent foreign particles from getting
into ABSCM&H/U.
Apply a coat of rust-preventive wax (Nippeco LT or
GB) to bracket attaching bolt after tightening.
Do not pull harness disconnecting harness connec-
tor.

OPERATION
1. CHECKING THE HYDRAULIC UNIT ABS
OPERATION BY PRESSURE GAUGE
1) Lift-up vehicle and remove wheels.
2) Disconnect the air bleeder screws from the FL and FR
caliper bodies.
B4M0633A
3) Connect two pressure gauges to the FL and FR caliper
bodies.
CAUTION:
Pressure gauges used exclusively for brake fluid
must be used.
Do not employ pressure gauge previously used for
transmission since the piston seal is expanded which
may lead to malfunction of the brake.
NOTE:
Wrap sealing tape around the pressure gauge.
