Troubleshooting
ECM/PCM CONNECTOR A (49P)
Terminal side of female terminals
Is there battery voltage? YES
-Go to step 6.
NO
-Repair an open in the wire between the under-hood fuse/relay box and the ECM/PCM. If the wire is OK, replace the under-hood fuse/relay box (see page 22-75).
6. Turn the ignition switch to LOCK (0).
7. Connect ECM/PCM connector A (49P) terminals No. 5 and No. 6 to body ground with a jumper wire.
