69. Check for continuity between PGM-FI main relay 1
4P connector terminal No. 4 and ECM/PCM
connector terminal A6.
Test PGM-FI main relay 1 (see page 22-70). If
the relay is OK, update the ECM/PCM if it does not
have the latest software (see page 11-227), or
substitute a known-good ECM/PCM (see page 11-7),
then recheck. If the symptom/indication goes away
with a known-good ECM/PCM, replace the original
ECM/PCM (see page 11-228).
Repair open in the wire between the ECM/
PCM (A6) and PGM-FI main relay 1. 70. Turn the ignition switch to LOCK (0).
71. Remove PGM-FI main relay 1 (C) from the under-
hood fuse/relay box.
72. Measure the voltage between PGM-FI main relay 1 4P connector terminal No. 1 and body ground.
Go to step 73.
Replace the under-hood fuse/relay box
(see page 22-65).

18. Turn the ignition switch to LOCK (0).
19. Replace the throttle body; K20Z2 engine (see page
11-348), K20Z3 engine (see page 11-349).
20. Reconnect all connectors.
21. Turn the ignition switch to ON (II).
22. Reset the ECM/PCM with the HDS.
23. Do the ECM/PCM idle learn procedure (see page 11-310).
24. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the throttle body and the ECM/PCM,
then go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
25. Reconnect all connectors.
26. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
27. Check for Temporary DTCs or DTCs with the HDS.

terminals at the throttle body and the ECM/PCM. If
the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then recheck. If the
ECM/PCM was substituted, go to step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Do the ETCS TEST in the INSPECTION MENU with the HDS.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
