42 -BODY > 42B-KEYLESS OPERATION SYSTEM (KOS) > TROUBLESHOOTING > DIAGNOSIS CODE PROCEDURES > B1163 Coding data mismatch
Code No. B1163 Coding data mismatch
 
 
caution
  • When diagnosis code No.B1163 is set, be sure to diagnose the CAN bus line.
  • When replacing the ECU, always check that the communication circuit is normal.
 
 
DIAGNOSTIC FUNCTION
When the coding data registered in KOS&OSS-ECU is different from the coding data transmitted on the CAN bus, KOS&OSS-ECU sets diagnosis code No.B1163. At the same time, KOS&OSS-ECU displays the power supply system error warning to the combination meter, and flashes the indicator of engine switch in amber.
 
 
JUDGEMENT CRITERIA
Judgement Criterion
  • A coding data is received which is different from the current coding status.
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus line
  • ETACS-ECU malfunction
  • ETACS-ECU has been interchanged between two vehicles
  • Malfunction of KOS&OSS-ECU
 
 
DIAGNOSIS PROCEDURE
1. M.U.T.-IIISE CAN bus diagnosis
2. ETACS-ECU diagnosis code check
3. ETACS-ECU coding data check
4. KOS&OSS-ECU diagnosis code recheck
