3. Check contamination, damage or stuck on ISCA.
4. Check the operating sound when key turns "OFF" to "ON".
5. Is ISCA O.K?
  YES
  - Go to 2 "ISCA check" procedure.

Is the measured resistance within specifications?
YES
- Substitute with a known - good ECM/PCM and check for proper operation.
- If the problem is corrected, replace ECM/PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by ECM/PCM.
Before or after testing ECM/PCM on the vehicle, use this function to reuse the ECM/PCM

NO
- Substitute with a known - good ISCA and check for proper operation.
- If the problem is corrected, replace ISCA and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
