warning lamp Ð Diagnosis mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is
detected in User mode.
1. Turn ignition switch ªONº.
2. After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion switch ªOFFº within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch ªONº.
SRS is now in Diagnosis mode.
6. ªAIR BAGº warning lamp operates in Diagnosis mode as fol-
lows:
NOTE:
If SRS does not enter Diagnosis mode even though malfunction
is detected in User mode, check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 7, page RS-53.
If the battery voltage is OK, replace the diagnosis sensor unit.

Checking Steering Wheel Play
1. With wheels in a straight-ahead position, check steering
wheel play.
Steering wheel play:
35 mm (1.38 in) or less
2. If it is not within specification, check steering gear assembly
when front suspension and axle, steering gear assembly and
steering column are mounted correctly.
Checking Neutral Position on Steering Wheel
Pre-checking
lMake sure that wheel alignment is correct.
Wheel alignment:
Refer to SDS in FA section
lVerify that the steering gear is centered before removing the
steering wheel.
Checking
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel
and reinstall it correctly.
3. If the neutral position is between two serrated teeth, loosen
tie-rod lock nut and move tie-rod in the opposite direction by
the same amount on both left and right sides to compensate
for error in the neutral position.
Front Wheel Turning Angle
1. Rotate steering wheel all the way right and left; measure
turning angle.
Turning angle of full turns:
Refer to SDS in FA section
2. If it is not within specification, check rack stroke.
Rack stroke ªSº:
Refer to SDS (ST-23)
Checking Gear Housing Movement
1. Check the movement of steering gear housing during station-
ary steering on a dry paved surface.
lApply a force of 49 N (5 kg, 11 lb) to steering wheel to check
the gear housing movement.
Turn off ignition key while checking.
Movement of gear housing:
 2 mm ( 0.08 in) or less
2. If movement exceeds the limit, replace mount insulator after
confirming correct installation of gear housing clamps.

CAUTION:
lThe rotation of the spiral cable (SRS ªAir bagº component
part) is limited. If the steering gear must be removed, set
the front wheels in the straight-ahead direction. Do not
rotate the steering column while the steering gear is
removed.
lRemove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
