12. Inspect the No. 20 IG1 (40A) fuse in the under-hood fuse/relay box.

Is the fuse OK?

YES | - Repair open in the wire between the No. 20 IG1 (40A) fuse and the gauge assembly. If the wires are OK, test the ignition switch (see page 22-83).
NO | - Repair short in the wire between No. 20 IG1 (40A) fuse and the under-dash fuse/relay box. Also replace the No. 20 IG1 (40A) fuse.

13. Try to start the engine.

Does the engine start?

YES | - Go to step 14.
NO | - Go to step 17.

14. Turn the ignition switch OFF.
15. Connect ECM/PCM connector terminal E31 and body ground with a jumper wire.

16. Turn the ignition switch ON (II).

Is the MIL on?

YES | - Substitute a known-good ECM/PCM and recheck (see page 11-6). If symptom/indication goes away, replace the original ECM/PCM.
NO | - Check for an open in the wire between the ECM/PCM (E31) and the gauge assembly. Also check for a blown MIL bulb. If the wires and the bulb are OK, replace the gauge assembly.

17. Turn the ignition switch OFF.

18. Inspect the No. 6 ECU (ECM/PCM) (15A) fuse in the under-hood fuse/relay box.

Is the fuse OK?

YES | - Go to step 25.
NO | - Go to step 19.

19. Remove the blown No. 6 ECU (ECM/PCM) (15A) fuse in the under-dash fuse/relay box.
20. Remove the PGM-FI main relay 1 (A).
