Inspection
Brake system warning lamp
1. Disconnect the connector from the brake fluid level sensor.
2. Connect a jumper wire between “G/Y” and “6” terminal
(body ground).
3. Start the engine and check that the BRAKE warning lamp
illuminates.
Caution
l Be sure that the parking brake is fully released be-
fore checking.
4. If there is no illumination, check the fuse, bulb, and wiring
harness.
Brake fluid level sensor
Connect an ohmmeter to each terminal of the brake fluid lev-
el sensor connector.
Check for continuity when the float is moved up and down.
The sensor is good if there is continuity when the float is be-
low the “MIN” mark, and if there is no continuity when the
float is above the “MAX” mark. If the sensor does not pass
this test, replace it.
Fuel-level warning lamp
1. Disconnect the connector from the fuel tank unit.
2. Connect the connector terminal “W/R” to the body ground.
3. Start the engine and check that the FUEL warning lamp il-
luminates.
4. If there is no illumination, check the fuse, warning lamp, and
wiring harness.
Alternator warning lamp
1. Start the engine, connect the connector terminal “W/B” to
a body ground.
2. Check that the alternator warning lamp illuminates.
3. If there is no illumination, check the warning lamps, wiring
harness and alternator. Replace or repair as necessary.
Engine oil pressure warning lamp
1. Disconnect the connector from the oil pressure switch.
2. Start the engine and connect the connector terminal “Y/R”
to a body ground.
3. Check that the “OIL” warning lamp illuminates. If it does
not, replace the sender switch or repair the wiring harness
if bulb is not burnt out.

I WARNING SYSTEM
Washer fluid warning lamp
1. Disconnect the connector from the washer fluid level sensor.
2. Start the engine and with a jumper wire to connect the con-
nector terminal “a” (LGIW) to a body ground.
3. Check that the washer fluid warning lamp illuminates.
If it does not and the bulb is not burnt out, replace the fluid
level sensor or repair the wiring harness.

Seat belt warning lamp
1, Remove the CPU.
2. Connect the connector J terminal (joint box side) to a body
ground.
3. Turn ignition switch to ON and confirm that BELT warning
lamp illuminates for about 6 seconds.
4. If there is no illumination, check the fuse, warning readout
and wiring harness.
Check bulb, CPU and wiring harness and switch, repair or
replace as necessary.
Malfunction indicator lamp
1, Connect the “Y/B” wire to a body ground.
2. Start the engine and check that the warning lamp illuminates.
3. If there is no illumination, check the meter fuse, bulb, and
wiring harness between the instrument cluster and the EGI
control unit.

U AIR CONDITIONER
DRY AND WET THERMOMETER

Performance test
After finishing repairs, conduct a performance test of the air
conditioning system as follows.
1. Connect the manifold gauge set. (Refer to page U-32.)
2. Start the engine and keep the engine speed at
1,500 rpm.
3. Operate the air conditioner at maximum cooling.
4. Open all windows and doors.
5. Place a dry-bulb thermometer in the center ventilator outlet.
6. Place a dry and wet thermometer close to the blower inlet.
7. Wait until the air conditioner outlet temperature stabilizes.
Stabilized condition
Blower inlet temperature: 25-35*C (77-95*F)
High-pressure side:
1,177-1,619 kPa (12.0-16.6 kg/cm’, 171-235 psi)
Note
l If the high-pressure side becomes too high, pour
cool water on the condenser. If It is too low, cover
the front of the condenser.
8. After the air conditioner stabilizes, read the dry and wet ther-
mometer at the air inlet.
9. Calculate the relative humidity from the chart below by com-
paring the wet- and dry-bulb readings.

On-vehicle Inspection
Thermoswitch
1. Remove the glove box.
2. Run the engine at idle.
3. Turn OFF the A/C switch and set the blower switch to the
highest position to operate the blower fan for a few minutes.
4. After a few minutes, turn OFF the blower switch and stop
the engine.
5. Disconnect the thermoswitch connector and check for con-
tinuity between terminals of the switch.

a-b Yes
6. If not as specified, replace the thermoswitch.
Note
l The thermoswitch contacts will be open if the
evaporator temperature is below 0.4 f 0.7OC (32.7
z!z 1.3OF).
Inspection
Thermoswitch
1. Immerse the sensing bulb in a container of ice water.
2. Check continuity between terminals of the switch as
specified.

3. If not as specified, replace the thermoswitch
Evaporator
1. Check the evaporator fins for blockage. If the fins are
clogged, clean them with compressed air.
Caution
l Never use water to clean the evaporator.
2. Check the fittings for cracks and other damage.
Replace the evaporator if necessary.
