2. INHIBITOR SWITCH
The inhibitor switch allows the back-up lights to turn on
when the select lever is in the R range and the starter
motor to start when the lever is in the N or P range.
When driving condition or starter motor operation is
erroneous, first check the shift linkage for improper opera-
tion. If the shift linkage is functioning properly, check the
inhibitor switch.

(1) Disconnect cable end from select lever.
(2) Disconnect inhibitor switch side connector.
(3) Check continuity in inhibitor switch circuits with
select lever moved to each position.
CAUTION:
Also check that continuity in ignition circuit does not
exist when selector lever is in R, D, 3, 2 and 1 ranges.
NOTE:
If inhibitor switch is inoperative, check for poor contact of
connector on transmission side. (Plastic body type inhibi-
tor switch)

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 following items.
(1) The engine starts operating when selector lever is
in position“P”, but not in other positions.
(2) The back-up light is lit when the selector lever is in
position“R”, 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“N”
to“R”without pushing the button.
(2) Check that selector lever does not move from“R”
to“P”without pushing the button.
(3) Check that selector lever does not move from“P”
to“R”without pushing the button and the brake pedal
depressed. [With ignition key set at“ON”.]
(4) Check that selector lever does not move from“3”to
“2”without pushing the button.
13) Check shift-lock system.
(1) Ensure ignition switch rotates from“ACC”to
“LOCK”when the selector lever is set at“P”. Also check
that ignition key can be removed from the“LOCK”posi-
tion only.
(2) Ensure selector lever moves from“P”to any other
position when the brake pedal is depressed with igni-
tion key set at“ON”or“START”.

D: ASSEMBLY
1) Insert combination switch to upper column shaft, and
install lower column cover with tilt lever held in the lowered
position. Then route ignition key harness and combination
switch harness between column cover mounting bosses.
2) Fit upper column cover to lower column cover, and
tighten combination switch and column cover.
Tightening torque:
1.2±0.2 N⋅m (0.12±0.02 kg-m, 0.9±0.1 ft-lb)
CAUTION:
Don’t overtorque screw.
E: INSTALLATION
1) Insert end of steering shaft into toe board grommet.
2) Tighten steering shaft mounting bolts under instrument
panel.
Tightening torque:
25±5 N⋅m (2.5±0.5 kg-m, 18.1±3.6 ft-lb)
3) Connect ignition and combination switch connectors
under instrument panel.
4) Connect airbag system connector at harness spool.
NOTE:
Make sure to apply double lock.
5) Install universal joint.
(1) Align bolt hole on the long yoke side of universal
joint with the cutout at the serrated section of shaft end,
and insert universal joint.
(2) Align bolt hole on the short yoke side of universal
joint with the cutout at the serrated section of gearbox
assembly. Lower universal joint completely.
(3) Temporarily tighten bolt on the short yoke side.
Raise universal joint to make sure the bolt is properly
passing through the cutout at the serrated section.
(4) Tighten bolt on the long yoke side, then that on the
short yoke side.
Tightening torque:
24±3 N⋅m (2.4±0.3 kg-m, 17.4±2.2 ft-lb)
CAUTION:

Make sure that universal joint bolts is tightened
through notch in shaft serration.

Excessively large tightening torque of universal
joint bolts may lead to heavy steering wheel operation.
Standard clearance between gearbox to DOJ:
Over 15 mm (0.59 in)

unit solenoid valve is driven, the operation of the hydraulic
unit can be checked by means of the brake tester or pres-
sure gauge.
2) ABS sequence control can be started by diagnosis con-
nector or select monitor.
