SIL Troubleshooting
  1. Check for continuity between ECM connector terminal A48 and body ground.
Is there continuity?
YES -
Repair short in the wire between the ECM (A48) and the clutch switch (SIL).■
NO -
Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM. ■
