caution
  • If DTC No. B2206 is set, always diagnose the CAN bus line.
  • Before replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal.
 
 
DTC SET CONDITION
If the chassis number which is stored in the ETACS-ECU does not correspond to that which is stored in the engine control module (ECM), DTC No.B2206 will be set.
 
 
JUDGMENT CRITERIA
If the chassis number which is stored in the ETACS-ECU does not correspond to that which is stored in the ECM, the ETACS-ECU will determine that the system is defective.
 
 
TROUBLESHOOTING HINTS
  • Chassis number not written
  • The ETACS-ECU may be defective
  • The ECM may be defective
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), diagnose the CAN bus line.
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn off the power supply mode of the electric motor switch before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect the Scan Tool (M.U.T.-IIISE) ."
(2) Press the electric motor switch to turn on the power supply mode.
(3) Diagnose the CAN bus line.
(4) Press the electric motor switch to turn off the power supply mode.
Is the CAN bus line found to be normal?
Go to Step 2.
Repair the CAN bus line (Refer to GROUP 54C - Diagnosis ).
 
STEP 2. Check the chassis numbers which have been stored in the ECM.
Check whether the chassis numbers which have been stored in the ECM correspond to the actual chassis number written on the vehicle document.
Is the check result normal?
Go to Step 3.
Troubleshoot the engine. (Refer to GROUP 13A - DTC Chart )
 
STEP 3. Recheck for DTC.
Check again if the DTC is set in the ETACS-ECU.
(1) Erase the DTC.
(2) Press the electric motor switch to turn the power supply mode from "OFF" to "ON."
(3) Check if DTC is set.
Is the DTC set?
Replace with the coded ETACS-ECU.
The diagnosis is complete.
