Low Fuel Indicator Light

1. Disconnect the fuel gauge unit wire connector.

2. Turn the key switch on. Check that the bulb lights.
If operation is not correct, remove and check the bulb or circuit.
or If check whether low fuel turns on fuel input (B-24) at the
time of open and key on.

∗ meter is check at low fuel

Check level sensor operation

1. Remove the fuel gauge unit.

2. Apply battery voltage between terminal (B) and (C) through

a 1.12 watt bulb. Check that the bulb lights.

Note:
It will take a short time for the bulb light.
3. Submerge the sensor in fuel. Check that the bulb goes out.
If operation is not correct, replace the fuel tank unit.

BRAKE SYSTEM WARNING LIGHT

The brake system warning light comes on while the parking
brake is set and the engine run position.

RTW48AMH000101

Note:
The parking brake indicator light circuit is designed to
prevent driving of the vehicle with the parking brake on.
It does not indicate the condition of the parking brake
system.

The parking brake switch is in parallel with the brake fluid
switch.

The brake system warning light also comes on when reservoir
brake fluid level falls below the specified limit with the parking
brake released and the engine run position.
