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.

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 TROUBLESHOOTING GUIDE
Symptom: Blower motor does not operate.
Normal operation of blower motor
Blower motor speed is controlled by the blower switch and a resistor assembly in the blower unit.
When the blower switch is in the OFF position, the motor ground circuit is open and the blower motor does
not operate. When the switch is in the first (Low) position, current flow from the blower motor is restricted
by the three resistors in the resistor assembly, and the blower motor turns at low speed.
Changing the blower switch to the second (Mid), third (High), or fourth (Super-high) positions causes the
circuit resistance to decrease, and the blower motor speed to become correspondingly faster.
