  1. Turn the ignition switch ON (II).
  2. Check the ELD in the DATA LIST with the HDS. Is 72 A or more 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.

  7. Turn the ignition switch OFF.
  8. Jump the SCS line with the HDS.
  9. Disconnect ECM/PCM connector E (31P).
  10. Check for continuity between ECM/PCM connector terminal E15 and body ground. Is there continuity? YES - Repair short in the wire between the ECM/PCM (E15) and the ELD, then go to step 13 . NO - Go to step 20 .
  11. Turn the ignition switch OFF.

  22. Start the engine.
  23. Turn on the headlights.
  24. Check for Temporary DTCs or DTCs with the HDS. Is DTC P1297 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 go to step 22 . 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) ).
