CAN Communication Line Inspection

CAN Communication Line Inspection 1
1. IG key "OFF".
2. Connect all of control module connector
3. Measure resistance between DLC connector terminal No. 3 and No. 11
  Specification: About 60 Ω

4. Is the measured resistance within specification?
  YES
  - Go to open in harness as follow
  NO
  - If the measured resistance out of range in specification, replace the unit and go to "VERIFICATION OF VEHICLE REPAIR " procedure
  - If the measured resistance below 10Ω, check open to line between CAN High and CAN Low and go to "VERIFICATION OF VEHICLE REPAIR " procedure
  - If the measured resistance infinity (Ω), check short to line between CAN High and CAN Low and go to "VERIFICATION OF VEHICLE REPAIR " procedure
CAN Communication Line Inspection 2
1. IG key "OFF".
2. Disconnect all of control module connector
3. Measure resistance between ECM connector and cluster terminal
  Specification: About 120 Ω
