Low Fuel Indicator
- When ignition is turned on, ISO fuel pump indicator should come on if fuel level is less than 1/4 tank. Otherwise indicator should remain off. If indicator light comes on with more than 1/4 tank of fuel, turn ignition off.
- Disconnect fuel sending unit connection at tank. Install a 56-ohm resistor between harness connector Yellow/White wire terminal and ground. Turn ignition to RUN position and wait 2 minutes. Fuel gauge should read about 1/4 tank. Check indicator light.
- If indicator light is off, replace anti-slosh module mounted to rear of instrument cluster. If light is on, turn ignition off. Replace 56-ohm resistor with a 33-ohm resistor. Turn ignition to RUN position and wait 2 minutes. Fuel gauge should read about 1/8-1/4 tank. Check indicator light.
- If indicator light is off, replace anti-slosh module mounted to rear of instrument cluster. If indicator is on and fuel gauge reads approximately 1/8-1/4 tank, fuel gauge and anti-slosh module are okay. Check fuel tank sending unit for intermittent fault.
- If indicator is on and fuel gauge indicates more than 1/4 tank, check operation of fuel gauge. See FUEL GAUGE INOPERATIVE under GAUGES .
NOTE:
Magnetic-type gauges DO NOT
require an Instrument Voltage Regulator (IVR). There is no adjustment, calibration or maintenance required for these gauges. If gauge replacement is required, replace complete gauge unit.
