1. INSPECT FOG LIGHT SWITCH CONTINUITY
Switch positionTester connectionSpecified condition
OFF-No continuity
ON10 - 11Continuity
If continuity is not as specified, replace the switch.
2. INSPECT ENGINE ROOM R/B RELAY CIRCUIT(See
Pase BE-15)
HINT:
The foglight relay is built in engine room junction block. Also the
relay is constructed with a relay block that is in the junction block
as a unit. To disconnect the wire harness connecting with relay
block is impossible. If the relay has a malfunction, replace it with
junction block assembly wire harness together.

ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). and check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage:
12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
