42 -BODY > 42B-KEYLESS OPERATION SYSTEM (KOS) > TROUBLESHOOTING > DIAGNOSIS CODE PROCEDURES > B1147 ESL LIN communication fail
Code No. B1147 LIN communication stop control
 
 
cautionWhen replacing the ECU, always check that the communication circuit is normal.
 
 
DIAGNOSTIC FUNCTION
When an error has occurred to the termination processing of LIN communication with the electric steering lock and the processing cannot be terminated normally, KOS&OSS-ECU sets diagnosis code No.B1147.
 
 
JUDGEMENT CRITERIA
Check Conditions
  • At electric steering lock certification
Judgement Criterion
  • LIN communication with the electric steering lock cannot be terminated normally.
 
 
PROBABLE CAUSES
  • LIN bus line malfunction (open circuit, short to earth, or short to power supply in LIN line)
  • Damaged wiring harness or connector (open circuit or short to earth in PCO line, or open circuit in PWR line)
  • Electric steering lock malfunction
  • Malfunction of KOS&OSS-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check of open circuit in PWR line between electric steering lock connector and relay box (fuse) connector.
Is the check result normal?
Go to Step 2.
Repair the connector(s) or wiring harness.
 
STEP 2. Check of short to earth or open circuit in PCO line between electric steering lock connector and KOS&OSS-ECU connector.
noteBecause the conformity cannot be determined even when the digital tester is used to measure the voltage of PCO line between the electric steering lock connector and KOS&OSS-ECU connector, be sure to use the analogue tester (With the keyless operation key placed outside of the vehicle, if the tester needle swings to the battery voltage when the engine switch is operated, it is judged normal).
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Check of short to earth, short to power supply or open circuit in LIN line between electric steering lock connector and KOS&OSS-ECU connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. After performing the locking and unlocking operations of the electric steering lock, recheck the diagnosis code.
Is the diagnosis code set?
Replace the electric steering lock and register the chassis number (Refer to GROUP 00 - Precautions before Service - How to Perform Chassis Number (Chassis No.) Writing ). Then go to Step 5.
Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 5. Check whether the diagnosis code is set again.
Is the diagnosis code set?
Replace the KOS&OSS-ECU and register the ID codes (Refer to ).
The diagnosis is complete.
