1. CHECK USING THE DTC CHECK SHEET
DTC check sheet
(A) | Installation check | VDC: VDC CM | STA: Steering angle sensor |
(B) | Bus off detection | KPS: Keyless access CM | TCM: Transmission CM |
(C) | Data no-receive detection | AHL: Auto headlight beam leveler CM | EYE: Stereo camera |
(D) | Data abnormal detection | BIU: Body integrated unit | A/B: Airbag CM |
MFD: High grade MFD | EPS: Power steering CM | ||
A/C: A/C control panel | ECM: Engine CM | ||
MET: Combination meter | RDR: Radar sensor | ||
DCM: Data communication module |
1. Module installation check
(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.
2. 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” Subaru Select Monitor > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">
, 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. List of Diagnostic Trouble Code (DTC) > LIST">
3. 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.
2. EXAMPLE OF DTC DATA NOT RECEIVED
When 
(remote engine start CM vicinity) is open
NOTE:
No DTC remains, and the remote engine starter does not function.
When 
(steering angle sensor vicinity) is open
When 
(power steering CM vicinity) is open
NOTE:
Power steering CM may display U1120 (Auto Start Stop COMMUNICATION LOST).
