DLC Circuit Troubleshooting

  1. Check for continuity between ECM/PCM connector terminal C36 and body ground.
Is there continuity?
YES -
Go to Step 49 .
NO -
Replace the No. 9 FUEL PUMP (20 A) fuse, and update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM. ■
