ON-VEHICLE SERVICE
POWER STEERING37-16
WARNING
•If the vehicle continues to be driven after
the collision absorbing mechanism has
operated, the steering column shaft may
be damaged while it is in use.
•If there is a slack in the one-way capsule,
do not attempt to repair it but replace the
steering column shaft assembly.
Inspection Procedure
1. Remove the lower and upper column covers.
CAUTION
Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock
position.
3. Loosen the two steering column mounting bolts
(upper) by two turns.4. Hold the one-way capsules as shown, and then
try to lock them. If there is a slack in either of the
capsules, replace the steering column shaft
assembly.
NOTE: When installing a new steering column
shaft assembly, place the tilt lever in the lock
position, if it is not in place.
CAUTION
•Be careful that nothing is pinched between
the one-way capsules and the body.
•Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
5. If no problem is found during the inspection,
tighten the steering column mounting bolts to the
specified torque.
Tightening torque: 12 ± 2 N⋅m

ASSEMBLY REMOVAL
CAUTION
The tilt lever should be held in the lock position
until the steering column shaft is installed to the
vehicle. If the steering column is removed with
the tilt lever released, or the tilt lever is released
after the steering column shaft was removed from the vehicle, the steering column can not be
reinstalled correctly. If the steering column is
installed incorrectly, the collision energy
absorbing mechanism may be damaged.
1. Ensure that the tilt lever is in the lock position, and
remove the steering column mounting bolts.

CHASSIS ELECTRICAL54A-38
TECHNICAL DESCRIPTION (COMMENT)
The engine-ECU and its associated components, the
combination meter assembly, the wiring harness, or
the connector(s) may be defective.
TROUBLESHOOTING HINTS
•Malfunction of the vehicle speed sensor
•Malfunction of the engine-ECU
•Malfunction of the combination meter assembly
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III actuator test
(1) Connect the MUT-II/III to the diagnosis connector.(2) Use the MUT-II/III to enter simulated vehicle
speed.
Q: Does the speedometer show that simulated vehicle
speed?
YES :
Go to Step 6.
NO : Go to Step 2.
STEP 2. Check the output shaft speed sensor.
(MUT-II/III diagnosis code)
(1) Connect MUT-II/III to the diagnosis connector.
(2) Turn the ignition switch to the "ON" position.

3 − 10 kiloohms resistor as shown in the
illustration.
2. Turn the shaft of the vehicle speed sensor and
check that there is voltage between terminals 2 −
3. (1 turn = 4 pulses)
3. If within the standard value, the vehicle speed
sensor is OK.
If not within the standard value, replace the
vehicle speed sensor.
