1. Write "-" marks in the field for installation check if the vehicle to be inspected does not have relevant module.
2. Write "-" marks in all blank fields on the same row that the "-" mark has filled in.
Bus off detection/data not received
NOTE: It becomes impossible for CAN diagnostic module to read DTC, if there is a current malfunction of open harness (data not received). If this occurs, perform the "Check using the check sheet of communication for initializing" < Ref. to CHECK USING THE CHECK SHEET OF COMMUNICATION FOR INITIALIZING , COMMUNICATION FOR INITIALIZING IMPOSSIBLE, Subaru Select Monitor. >, and use this sheet to confirm that the corresponding part becomes the past malfunction.
1. Mark "X" in the field corresponding to the DTCs that has been detected by each module in the check sheet.
2. Identify and repair the faulty part by referring to the example of DTC data not received. < Ref. to EXAMPLE OF DTC DATA NOT RECEIVED , LIST, List of Diagnostic Trouble Code (DTC). >
Data abnormal detection
NOTE: If any "BUS OFF" or "NO-RECEIVE DATA" condition is detected, perform the diagnosis for these problems first.
1. If several modules detect the DTC for the same module, replace the detected module.
2. If one module detects the DTC, replace the module of the detected side.
3. If it does not return to the normal operation, re-install the module which has been replaced, and replace the module of the detected side.
4. If it does not return to the normal operation, replace both modules.
