7. If the 2FH and 2HP wires have good 

continuity, check for battery voltage on the 
2A-03 wire at the Fuel Heater Relay. If battery 
voltage is not present, check the continuity of 
2A-03 wire between the Fuel Heater Relay 
and the 2A (J25) screw terminal on the base 
controller. Also check to make sure the 2A-03 
wire connection at the 2A (J25) screw 
terminal is clean and tight.

8. If battery voltage is present on the 2A-03 wire 

at the Fuel Heater Relay, check for battery 
voltage on the 8FH-02 wire at the Fuel Heater 
Relay. If battery voltage is not present, check 
the continuity of 8FH-02 and 8FH-01 wires 
between the Fuel Heater Relay and pin 7 in 
the J16 connector on the base controller. Also 
check to make sure the wire connections are 
clean and tight.

9. If battery voltage is present on the 8FH-02 

wire at the Fuel Heater Relay, check for a 
defective Fuel Heater Relay.
