  1. Start the engine, and let it idle.
  2. Check the ELD in the DATA LIST with the HDS. Is 0.2 A or less indicated? YES - Go to step 3 . NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ELD and the ECM/PCM.
  3. Turn the ignition switch OFF.
  4. Disconnect the ELD 3P connector.
  5. Turn the ignition switch ON (II).
  6. Measure voltage between ELD 3P connector terminal No. 1 and body ground. Is there battery voltage? YES - Go to step 7 . NO - Check the No. 3 IG METER (10 A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the No. 3 IG METER (10 A) fuse and the ELD, then go to step 14 .
  7. Turn the ignition switch OFF.
  8. Connect ELD 3P connector terminal No. 3 to body ground with a jumper wire.
  9. Jump the SCS line with the HDS.
  10. Disconnect ECM/PCM connector E (31P).
  11. Check for continuity between ECM/PCM connector terminal E15 and body ground. Is there continuity? YES - Go to step 12 . NO - Repair open in the wire between the ECM/PCM (E15) and the ELD, then go to step 14 .
  12. Check for continuity between ELD 3P connector terminal No. 2 and body ground. Is there continuity? YES - Go to step 13 . NO - Repair open in the wire between the ELD and G301, then go to step 14 .
  13. Replace the ELD (see «ELD REPLACEMENT»(ref-291411-S07722878022008072800000) ).
  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 «ECM/PCM IDLE LEARN PROCEDURE»(ref-291413-S23447131872008072800000) ).
  18. Check for Temporary DTCs or DTCs with the HDS. Is DTC P1298 indicated? YES - Go to step 19 . NO - Troubleshooting is complete.
  19. Update the ECM/PCM if it does not have the latest software (see «UPDATING THE ECM/PCM»(ref-291410-S41633658632008072800000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-291410-S09944723422008072800000) ).
  20. Check for Temporary DTCs or DTCs with the HDS. Is DTC P1298 indicated? YES - Check for poor connections or loose terminals at the ELD and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-291410-S09944723422008072800000) ), then recheck. If the ECM/PCM was substituted, go to step 1 . NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see «ECM/PCM REPLACEMENT»(ref-291411-S17209936142008072800000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
