Component Inspection

Check IMS
1. Connect scantool to Data Link Connector (DLC).
2. Ignition "ON" & engine "OFF"
3. Substitute with a known-good IMS and Check if the DTC is erased.
4. Is the DTC erased?
  YES
  
  Substitute with a known-good IMS and check for proper operation.
  
  If the problem is corrected, replace IMS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  
  NO
  
  Go to " 2Check power seat slide motor" procedure.
