BATTERY CHECK

Scheme 250

Scheme 251

1. Ensure that the battery electrolyte level A within the range B shown in the figure. Add if the level is lower than the specified range.
2. Use a hydrometer and temperature gauge to check the specific gravity of the electrolyte. Standard value: 1.220 - 1.290 [at 20°C (68°F)] The specific gravity of electrolyte depends on its temperature. Use the formula below to determine the proper value. Conversion on centigrade D 20 =(t - 20) x 0.0007 + Dt Conversion on Fahrenheit D 20 =(t - 68) x 0.0007 + Dt D 20 : Specific gravity as if electrolyte temperature is 20°C (68°F) D t : Measured specific gravity t : Measured temperature

BATTERY CHARGING

Battery electrolyte temperature may temporarily be allowed to rise to 55°C (131°F). Increase of electrolyte temperature above 55°C (131°F) is harmful to the battery, causing deformation of battery cell, decrease in life of battery, etc.

CHARGE RATE

Recommended rate and time for fully discharged condition (flat discharged) is shown below. When the specific gravity of electrolyte keeps 1.22 - 1.29 for more than one hour, charging should be stopped.

IGNITION KEY REMINDER TONE ALARM

The ignition key reminder tone alarm will sound under the following condition, and warn the driver to remove the ignition key.

1. The driver's door is opened when the ignition switch is at "LOCK" (OFF) or "ACC" position without removing the ignition key. However, the light reminder tone alarm will take precedence over this function.

DOOR LOCK PREVENTION FUNCTION

If the key is left in the ignition switch while the driver's door opened or the assistant door opened, all doors are automatically unlocked to prevent locking the ignition key in the vehicle after the door is locked.

IGNITION SWITCH CONTINUITY CHECK

Disconnect ignition switch connector C-308 without removing the ignition switch and steering lock cylinder. Then check the continuity.

ENCRYPTED CODE REGISTRATION CRITERIA TABLE

The ignition key contains a transponder (small transmitter), which retains an unique encrypted code. When replacing the parts of the immobilizer system, always register the encrypted code or VIN, or both of them according to the list below. The ETACS-ECU can retain a maximum of eight different encrypted codes. This means that a maximum of eight ignition keys can be registered.

ENCRYPTED CODE REGISTRATION CRITERIA CHART

Note. The engine does not start until the matching has been completed.

TERMINAL NO. AND INSPECTION CONDITION

ENCRYPTED CODE REGISTRATION PROCEDURE

If the ignition key is replaced or additional keys are requested, the encrypted codes of all ignition keys must be registered. (A maximum of eight ignition keys can be registered.)

Note. The encrypted codes can be registered using the ignition key and barcode No.

Scheme 256

PRECAUTIONS DURING SERVICE

If all functions do not work, check the diagnostic trouble code, and repair the system. Then, repeat the operation.

If a wrong password is entered consecutively five times by scan tool (MUT-III sub assembly), the immobilizer-ECU judges that the system is operated incorrectly. Then, the engine immobilization mode is set, and the ECU stops the engine and all special functions is stopped. In addition, when the ignition switch is held at the ON position for approximately 20 minutes with engine immobilization mode, "incorrect operation, engine immobilization mode" is cancelled.

ENCRYPTED CODE REGISTRATION USING IGNITION KEY < REGISTRATION USING IGNITION KEY ONLY >

When the ignition key is lost or additional keys are requested, the ignition key must be used to register encrypted codes.

Scheme 257

1. Turn the ignition switch to the "ON" position using the registered ignition key and keep it there for 5 seconds.
2. Turn the ignition switch to the "LOCK" (OFF) position, and remove the registered ignition key.
3. Within 30 seconds after the ignition key is removed, insert the other registered ignition key that has already been registered and turn the ignition switch to the "ON" position.
4. The immobilizer indicator light starts flashing in approximately 10 seconds after the ignition switch is turned to the "ON" position.
5. When the immobilizer indicator light starts flashing, turn the ignition switch to the "LOCK" (OFF) position and remove the ignition key. NOTE: When an error occurs while the immobilizer indicator light is flashing, the immobilizer indicator light extinguishes.
6. Within 30 seconds after the immobilizer indicator light flashes in Step 5 , insert the ignition key to be added and turn the ignition switch to the "ON" position.
7. When registering another ignition key, repeat the procedure from the beginning. NOTE: < When the additional ignition key cannot be registered > When the immobilizer indicator is not illuminated during registration When the immobilizer indicator light does not change in 3 seconds after carrying out Step 6 < When the additional registration of the ignition key terminates automatically > When 30 seconds have passed before inserting the ignition key in Step 3 after the ignition key is removed in Step 2 . When 30 seconds have passed after the immobilizer indicator light flashed

ENCRYPTED CODE REGISTRATION USING BARCODE NO.

When the ignition key that starts the engine is replaced due to the replacement of the ignition key set, the ignition key cylinder, etc., the barcode No. must be used to register encrypted codes.

LUMINOUS INTENSITY MEASUREMENT

1. Set the headlights to high-beam
2. Using a photometer, and following its manufacturer's instruction manual, measure the headlight center intensity and check to be sure that the limit value is satisfied. Limit: 40,000 cd or more {When a screen is set 18.3m (60 feet) ahead of the vehicle}

Note. When measuring the intensity, maintain an engine speed of 2,000 r/min, with the battery fully charged.

There may be special local regulations pertaining to headlight intensity. Be sure to make any adjustments necessary to satisfy such regulations.

If an illuminometer is used to make the measurements, convert its values to photometer values by using the following formula.

I =E x r 2 Where

1. I = intensity (cd)
2. E = illumination (lux)
3. r = distance (m) from headlights to illuminometer

Scheme 279

1. Disconnect the headlight connector.
2. Remove the headlight bulb by turning it counterclockwise as shown in illustration. CAUTION: Do not touch the surface of the bulb with hands or dirty gloves as the bulb may fail after a short time. If the surface does become dirty, clean it with alcohol or thinner, and let it dry thoroughly before installing.
3. Install the headlight bulb to the headlight by pushing it in and twisting it clockwise.

Scheme 280

1. Disconnect the front side-marker, front turn-signal light and parking light connector.
2. Remove the socket with the bulb by turning it counterclockwise as shown in illustration. CAUTION: Do not touch the surface of the bulb with hands or dirty gloves as the bulb may fail after a short time. If the surface does become dirty, clean it with alcohol or thinner, and let it dry thoroughly before installing.
3. Pull out the bulb from the socket, and then replace the bulb.
4. Install the socket to the headlight by pushing it in and twisting it clockwise.
