Note The temperature is an ambient temperature of the battery that has been exposed to for the preceding few hours.

BA-ITERY CHARGING

MYEICL

Caution When batteries are being charged, an explosive gas forms beneath the cover of each cell. Do not smoke near batteries on charge or which have recently been charged. Do not break live circuits at the terminals of the batteries on charge. A spark will occur where the live circuit is broken. Keep all open flames away from the battery.Battery electrolyte temperature may temporarily be allowed to rise to 55OC (131 OF). Increase of electrolyte temperature above 55OC (131 F) is harmful to the battery, causing deformation of battery cell, decrease in life of battery, etc.

When the dot appears or when maximum charge shown below is reached, charging should be stopped. NOTE When the charging is performed at 5 amps, charging is virtually loo:! three hours after the indicators indication changes from white to blue. Use fast charging only in an emergency. If the indicator does not turn to blue even after the battery is charged, the battery should be replaced; do not overcharge.

(1) Disconnect the connector of the fuel gauge unit; the F side is indicated when terminal 3 (FWD) or 2 (AWD) is then grounded. l Check the fuel gauge. 2. The engine coolant temperature gauge doesnt function, or shows the incorrect indication. (1) The H side is indicated when the connector of the engine coolant temperature gauge unit is disconnected and then grounded. l Check the engine coolant temperature gauge unit. 3. Systems dependent upon control according to the vehicle speed do not function correctly. l Check the reed switch (located within the speedometer). 4. The meter illumination light does not illuminate. (1) The tail lights illuminate. l Check the rheostat.

When the ignition key is at the ON position, the fuel gauge is activated. When there is much fuel, the units resistance is small and the current flowing in the circuit is great, so the gauges indicator indicates in the F area. When there is little fuel, the units resistance is high and the current flowing in the circuit is small, so the gauges indicator indicates in the E area. When the ignition key is at the ON position, the engine coolant temperature gauge is activated. When the engine coolant temperature is high, the units resistance is low and there is a great flow of current in the circuit, so the gauges indicator indicates in the H area. When the engine coolant temperature is low, the units resistance is high and there is a small flow of current in the circuit, so the gauges indicator indicates in the C area.

METERS AND GAUGES - Meters and GaugesOperation Seat belt warning This warning light warns the driver and front passenger to fasten their seat belts. If one or more seat belts are not fastened, the automatic seat belt control unit detects that fact and causes the warning light to be illuminated or flash. How long the light is illuminated or how many times it flashes depends on whether only one, or both of the belts remain unfastened. The seat belt warning light will flash for about six seconds when the ignition key is turned to the ON position. If at this time the drivers seat belt is not buckled, the alarm buzzer will sound four times in synchronism with the flashing of the warning light. Brake warning

(1) Connect the scan tool to the data link connector (located at the right side of the junction block). (2) With the ignition switch at the ACC position, set the scan tool to the special test setting. (3) Check whether the buzzer of the scan tool sounds one time when each of the switches noted below is operated. Input signals are being input to the electronic control unit if the buzzer sounds, so the operation of that switch can be considered satisfactory; if the buzzer does not sound, check that switch or the wiring for an abnormal condition.l l

Take out the plug, and check for a worn edge on the element spot connection, and for shreds of tobacco or other material on the element. Using an ohmmeter, check the continuity of the element.

CAUTIONS FOR USE OF THE CIGARETTE LIGHTER SOCKET AS AUXILIARY POWER SOURCE 1. When using a plug-in tYpe of accessory, do not use anything with a load of more than 120W. 2. It is recommended that only the lighter be inserted in the receptacle. Use of plug-in type accesories may damage the receptacle and result in poor retention of the lighter. NOTE The specified load should be strictly observed, because overloaded cord burns the ignition switch and harness.

Troubleshooting/Service Adjustment Procedures

OPERATION l When the defogger switch is turned ON with the ignition switch in ON position, the defogger relay is energized causing defogger to operate. l At the same time, the defogger indicator light lights up indicating that the defogger is in operation. l The defogger timer keeps the defogger relay remaining energized for 10 minutes after the defoaaer switch has been turned ON. If the defo;ger switch is pushed a second time during this lo-min. period, timer is cancelled and the defogger is turned off.

TROUBLESHOOTING

HINTS

1. Defogger is inoperative. 1) Indicator does not come on, either. l Check multi-purpose fuse No.@. l Check defogger relay. 2) Indicator comes on. l Check defogger. 2. Defogger timer is inoperative. l Check defogger timer. NOTE For information concerning the defogger relay a n d defoqqer timer, refer to P.54-163 a n d 54-164. -,
