  1. Turn the ignition switch to ON (II).
  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 to LOCK (0).
  4. Disconnect the ELD 3P connector.
  5. Turn the ignition switch to ON (II).
  6. Measure the 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 ALTERNATOR (10 A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the No. 3 ALTERNATOR (10 A) fuse and the ELD, then go to step 13 .
  7. Turn the ignition switch to LOCK (0).
  8. Jump the SCS line with the HDS.
  9. Disconnect ECM/PCM connector A (44P).
  10. Check for continuity between ELD 3P connector terminal No. 3 and ECM/PCM connector terminal A23. Is there continuity? YES -Go to step 11. NO -Repair open in the wire between the ECM/PCM (A23) and the ELD, then go to step 13 .
  11. Check for continuity between ELD 3P connector terminal No. 2 and body ground. Is there continuity? YES -Go to step 12. NO -Repair open in the wire between the ELD and G301 (see «ENGINE COMPARTMENT WIRE HARNESS (LEFT BRANCH) (EXCEPT SI MODEL)»(ref-355127-S33756786102010012000000) ), then go to step 13 .
  12. Replace the ELD (see «ELD REPLACEMENT»(ref-355126-S05481440182010012000000) ).
  13. Reconnect all connectors.
  14. Turn the ignition switch to ON (II).
  15. Reset the ECM/PCM with the HDS.
  16. Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-255517-S24591238122007060300000) ).
  17. Check for Pending or Confirmed DTCs with the HDS. Is DTC P1298 indicated? YES -Go to step 18. NO -Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the «INDICATED DTC'S TROUBLESHOOTING»(ref-355126-S38482784232010012000000) .
  18. Update the ECM/PCM if it does not have the latest software (see «ECM/PCM UPDATE»(ref-355126-S21746322412010012000000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ).
  19. Check for Pending or Confirmed 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-379879-S00676494072010121600000) ), 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-355126-S35548339322010012000000) ). If any other Pending or Confirmed DTCs are indicated, go to the «INDICATED DTC'S TROUBLESHOOTING»(ref-355126-S38482784232010012000000) .
