10) After completion of fitting, make sure that the
selector lever operates smoothly all across the
operating range.
11) Connect the harnesses and check the follow-
ing items.
(1) The engine starts operating when selector
lever is in position ªPº, but not in other positions.
(2) The back-up light is lit when the selector
lever is in position ªRº, but not in other positions.
12) Check selector lever operation.
WARNING:
Stop the engine while checking operation of
selector lever.
(1) Check that selector lever does not move
from ªNº to ªRº without pushing the button.
(2) Check that selector lever does not move
from ªRº to ªPº without pushing the button.
(3) Check that selector lever does not move
from ªPº to ªRº without pushing the button.
(4) Check that selector lever does not move
from ª3º to ª2º without pushing the button.

13) Check shift-lock system.
(1) Ensure ignition switch rotates from ªACCº to
ªLOCKº when the selector lever is set at ªPº.

4) Within 0.5 seconds after the ABS warning light
goes out, depress the brake pedal and hold it
immediately after ignition switch is turned to ON.
CAUTION:
Do not depress the clutch pedal.
NOTE:
IWhen the ignition switch is set to on, the brake
pedal must not be depressed.
IEngine must not operate.
5) After completion of ABS sequence control, turn
ignition switch OFF.
2. OPERATIONAL GUIDELINES OF THE
ABS SEQUENCE CONTROL WITH
SELECT MONITOR
NOTE:
IIn the event of any trouble, the sequence con-
trol may not be operative. In such a case, activate
the sequence control, referring to ªOPERATIONAL
GUIDELINES OF THE ABS SEQUENCE CON-
TROL WITH DIAGNOSIS CONNECTORº. 4-4 [W15D1].>
IWhen the diagnosis terminal is connected to the
diagnosis connector, the sequence control will not
operate.
1) Connect select monitor to data link connector
beside driver's seat instrument panel lower cover.
2) Turn ignition switch ON.
3) Turn select monitor switch ON.
4) Put select monitor to {ABS/TCS} mode.
5) When {Function check sequence} is selected,
`ABS sequence control' will start.
6) The message `Press Brake Pedal Firmly' is dis-
played as follows:
(1) When using the brake tester, depress brake
pedal with braking force of 981 N (100 kg, 221
lb).
(2) When using the pressure gauge, depress
brake pedal so as to make the pressure gauge
indicate 3,432 kPa (35 kg/cm
2, 498 psi).
CAUTION:
Do not depress the clutch pedal.
7) When the message ªPress YESº is displayed,
press YES key.
8) Operation points will be displayed on select
monitor.
3. CONDITIONS FOR COMPLETION OF
ABS SEQUENCE CONTROL
When the following conditions develop, the ABS
sequence control stops and ABS operation is
returned to the normal control mode.
1) When the speed of at least one wheel reaches
10 km/h (6 MPH).
2) When terminal No. 3 or No. 6 are separated
from diagnosis terminals. (When select monitor is
not used.)
3) When the brake pedal is released during
sequence control and the braking lamp switch is
set to off.
4) When brake pedal is depressed after ignition
key is turned to ON, and before ABS warning light
goes out. (When select monitor is not used.)
5) When brake pedal is not depressed after igni-
tion key is turned to ON, and within 0.5 seconds
after ABS warning light goes out. (When select
monitor is not used.)
6) After completion of the sequence control.
7) When malfunction is detected. (When select
monitor is used.)
