If the Hazard Switch (X220) is depressed, a pulsing voltage is applied to the Hazard Indicator which is permanently grounded by ground E200.

When the fuel gauge sender’s resistance falls below approximately 25 Ohms (6 liters/1.5 US gallons), the Low Fuel Warning Indicator will illuminate to warn the driver.
Main Beam Indicator
With the Headlamps turned on the Main Lighting Switch (X145), battery voltage is applied to the Main Beam Indicator which is also permanently grounded by ground E200.
Catalyst Warning Indicator (Japan Vehicles Only)
In case of a catalyst overheat, the catalyst thermocouples send a signal to the Catalyst Warning ECU’s which then provide battery voltage to the Catalyst Warning Relay (K172). The relay is energized and provides ground to the Catalyst Warning Indicator. The Catalyst Warning Indicator is also grounded by a 3 second timer as a bulb check.
