2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal 1 and 2.
Standard resistance: 21 - 27 W
If the resistance value is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals.
Check that the operation noise can be heard from the so-
lenoid.
If the solenoid does not operate, replace the solenoid.
3. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that continuity exists between each terminal.

6. INSPECT FUEL SENDER GAUGE VOLTAGE
(a) Apply voltage (4.5 V - 5.0 V) between terminals 2 and 3.
(b) Measure voltage between terminals 1 and 2 for each float
position.
Float position mm (in.)Voltage (V)
F: Approx. 85.3 (3.36)Approx. 4.60 ± 0.1
1/2: Approx. 1.7 (0.67)Approx. 2.45 ± 0.1
E: Approx. 91.9 (3.62)Approx. 0.30 ± 0.1

INSPECTION
CAUTION:
Replace the seat belt assembly (outer belt, inner belt, bolts,
nuts or sill-bar) if it has been used in a severe impact. The
entire assembly should be replaced even if damage is not
obvious.
1. Except manual type:
RUNNING TEST (IN SAFE AREA)
(a) Fasten the front seat belts.
(b) Drive the car at 10 mph (16 km/h) and slam on the brakes.
Check that the belt locks and cannot be extended at this
time.
HINT:
Conduct this test in a safe area. If the belt does not lock, remove
the belt mechanism assembly and conduct the following static
check. Also, whenever installing a new belt assembly.
2. Driver 's seat belt (ELR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
HINT:
Before removing the pretensioner connector, be sure to read
the precautionary notice in the RS section.
(c) Tilt the retractor slowly.
(d) Make sure that the belt can be pulled out at a tilt of 15 de-
grees or less, and cannot be pulled out over 45 degrees
of tilt.
If a problem is found, replace the assembly.
3. Except driver's seat belt (ELR/ALR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
HINT:
Before removing the pretensioner connector, be sure to read
the precautionary notice in the RS section.
(c) Pull out the whole belt and measure the length of the
whole belt.
Then retract the belt slightly and pull it out again
(d) Make sure that the belt cannot be extended further.
If a problem is found, replace the assembly.
