12. Check for continuity between ELD 3P connector

terminal No. 2 and body ground.

Go to step 13.

Repair open in the wire between the ELD and

G301.

13. Reconnect the ELD 3P connector and ECM/PCM

connector E (31P).

14. Start the engine, and let it idle.

15. While measuring voltage between ECM/PCM

connector terminals A24 and E15, turn the
headlights on (high).

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).

Replace the ELD.

12. Check for continuity between ELD 3P connector

terminal No. 2 and body ground.

Go to step 13.

Repair open in the wire between the ELD and

G301, then go to step 14.

13. Replace the under-hood fuse/relay box.

14. Reconnect all connectors.

15. Turn the ignition switch ON (II).

16. Reset the ECM/PCM with the HDS.

17. Do the ECM/PCM idle learn procedure (see page

11-349).

18. Check for Temporary DTCs or DTCs with the HDS.

Go to step 19.

Troubleshooting is complete.

19. Update the ECM/PCM if it does not have the latest

software, or substitute a known-good ECM/PCM
(see page 11-6).

20. Check for Temporary DTCs or DTCs with the HDS.

If DTC P1298 is indicated, check for poor

connections or loose terminals at the ELD and the
ECM/PCM, then go to step 1. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).
