15. Remove the blown No. 6 ECU (ECM/PCM) (15 A)

fuse in the under-dash fuse/relay box.

16. Remove the glove box (see page 20-67).

17. Remove PGM-FI main relay 1 (FI MAIN) (A).

18. Check for continuity between body ground and the

PGM-FI main relay 1 (FI MAIN) 4P connector
terminals No. 2 and No. 4 individually.

Repair short in the wire between the No. 6

ECU (ECM/PCM) (15 A) fuse and PGM-FI main
relay 1 (FI MAIN). Also replace the No. 6 ECU (ECM/
PCM) (15 A) fuse.

Go to step 19.

19. Disconnect each of the components or connectors

below, one at a time, and check for continuity
between PGM-FI main relay 1 (FI MAIN) 4P
connector terminal No. 1 and body ground.

• PGM-FI main relay 2 (FUEL PUMP)
• ECM/PCM connector A (31P)
• Each injector 2P connector
• Idle air control (IAC) valve 3P connector
• Camsahft position (CMP) sensor B 3P connector
• Crankshaft position (CKP) sensor 3P connector
• Immobilizer control unit

Go to step 20.

Replace the component that made the short

to body ground go away when disconnected. If the
item is the ECM/PCM, update the ECM/PCM if it
does not have the latest software, or substitute a
known-good ECM/PCM (see page 11-6), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-284).
Also replace the No. 6 ECU (ECM/PCM) (15 A)
fuse.

20. Disconnect the connectors of these components:

• PGM-FI main relay 2 (FUEL PUMP)
• ECM/PCM connector A (31P)
• Injectors
• Idle air control (IAC) valve
• Camshaft position (CMP) sensor B
• Crankshaft position (CKP) sensor
• Immobilizer control unit

21. Check for continuity between PGM-FI main relay 1

(FI MAIN) 4P connector terminal No. 1 and body
ground.

Repair short in the wire between PGM-FI

main relay 1 (FI MAIN) and each item. Also replace
the No. 6 ECU (ECM/PCM) (15 A) fuse.

Replace PGM-FI main relay 1 (FI MAIN). Also

replace the No. 6 ECU (ECM/PCM) (15 A) fuse.

22. Inspect the No. 17 FUEL PUMP (15 A) fuse in the

under-dash fuse/relay box.

Go to step 34.

Go to step 23.

23. Remove the blown No. 17 FUEL PUMP (15 A) fuse

in the under-dash fuse/relay box.

24. Disconnect ECM/PCM connector E (31P).

25. Check for continuity between ECM/PCM connector

terminal E9 and body ground.

Go to step 26.

Replace the No. 17 FUEL PUMP (15 A) fuse,

and update the ECM/PCM if it does not have the
latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).

26. Remove PGM-FI main relay 2 (FUEL PUMP) (A).

27. Check for continuity between ECM/PCM connector

terminal E9 and body ground.

Repair short in the wire between the No. 17

FUEL PUMP (15 A) fuse and the ECM/PCM (E9), or
the No. 17 FUEL PUMP (15 A) fuse and PGM-FI
main relay 2 (FUEL PUMP) or the No.17 fuel pump
fuse (15 A) and the SRS unit. Also replace the
No. 17 FUEL PUMP (15 A) fuse.

Go to step 28.

28. Remove the rear seat cushion (see page 20-85).

29. Remove the access panel from the floor.

30. Disconnect the fuel pump 5P connector.

31. Check for continuity between fuel pump 5P

connector terminal No. 5 and body ground.

Repair short in the wire between the fuel

pump and PGM-FI main relay 2 (FUEL PUMP). Also
replace the No. 17 FUEL PUMP (15 A) fuse.

Go to step 32.

32. Reinstall PGM-FI main relay 2 (FUEL PUMP) (A).
