Fuel pump relay circuit
Fuel pump relay coil power Inspection
1.

Measure the voltage between "Coil power supply" terminal of "FUEL PUMP RELAY" on the "FAM" and chassis ground at IG key "ON" after removing "FUEL PUMP RELAY".

■ Specification : B+

2.

Is measured voltage within specification?

▶ Go to "Fuel pump relay control circuit inspection" procedure as below.

▶ Repair open/poor connection between "Coil power supply" terminal of "FUEL PUMP RELAY" on the "FAM" and the "MAIM RELAY_swtch" terminal.

Fuel pump relay control circuit inspection
3.

Connect probe of the LED volt circuit tester to "Coil control" terminal of "FUEL PUMP RELAY" on the "FAM".

4.

Perform "Fuel pump relay actuation test" by using GDS.

5.

Monitor LED tester lamp state.

■ Specification : LED tester lamp is "ON" when Fuel pump relay is operated by actuation test.

6.

Is the LED volt circuit tester lit (When fuel pump relay is operated by actuation test) ?

▶ The fuel pump relay circuit is OK.

▶ Repair open/poor connection between "Coil control" terminal of "FUEL PUMP RELAY" on the "FAM" and "Fuel Pump Relay Control" terminal of the "ECM" harness connector.
