J : Check Secondary Fuel Pump Driver Input Circuits For Short to High/Low (S/C Only): P1339

J1 : CHECK SECONDARY FUEL PUMP DRIVER INPUT CIRCUIT FOR SHORT TO BATTERY
1. Disconnect the PCM electrical connector, PI001.
2. Measure the voltage between PI001, pin 011 (Y) and GROUND.

Is the voltage greater than 1 volt?

Yes

REPAIR the short circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
Goto J2

J2 : CHECK SECONDARY FUEL PUMP DRIVER INPUT CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between PI001, pin 011 (Y) and GROUND.

Is the resistance less than 10,000 ohms?

Yes

REPAIR the short circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
Goto J3

J3 : CHECK SECONDARY FUEL PUMP DRIVER INPUT CIRCUIT FOR CONTINUITY
1. Disconnect the secondary fuel pump module electrical connector, CA283.
2. Measure the resistance between CA283, pin 007 (Y) and PI001, pin 011 (Y).

Is the resistance greater than 5 ohms?

Yes

REPAIR the circuit between CA283, pin 007 (Y) and PI001, pin 011 (Y). For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
INSTALL a new secondary fuel pump module. If the DTC is repeated, INSTALL a new PCM.
