CAN Register and Communication Line Inspection

CAN Register and Communication Line Inspection 1
1. Ignition OFF.
2. Connect all module connectors in proper locations.
3. Measure resistance between terminal 3 and 11 of diagnostic connector.
  Specification: About 60
4. Is the measured resistance within specification?
  YES
  
  Check Each Module connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
