CODE No. C2333 SAS malfunction
 
 
cautionBefore replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
OPERATION
The BSW-ECU (master) communicates with the steering wheel sensor via the gateway-ECU and the CAN bus lines.
 
 
CHECK CONDITION
Ignition switch is in the "ON" position.
 
 
DIAGNOSTIC FUNCTION AND JUDGEMENT CRITERIA
When the BSW-ECU (master) receives any of the signals below via CAN bus lines, the ECU sets diagnosis code No.C2333.
  • Implausible signal from the steering wheel sensor
  • Signal indicating internal error from the steering wheel sensor
  • Invalid steering wheel angle signal for at least 1.5 seconds from the steering wheel sensor
 
 
PROBABLE CAUSES
  • Improperly installed column switch assembly (integrated with steering wheel sensor)
  • Malfunction of the steering wheel sensor (incorporated in column switch assembly)
  • Malfunction of the CAN bus line
  • Malfunction of BSW-ECU (master)
 
 
DIAGNOSIS PROCEDURE
STEP 1. Steering wheel sensor installation check
Check that the steering wheel sensor is installed correctly.
Is the check result normal?
Go to Step 2.
Reinstall the column switch assembly (integrated with steering wheel sensor) (Refer to Column Switch Assembly Removal and Installation ).
 
STEP 2. M.U.T.-IIISE data list
Check the following data list (Refer to Data List Reference Table ).
  • Vehicle stopped (the steering wheel is in the neutral position)
 
Item No.Item nameNormal condition
7Steering wheel angle-5 to 5 deg
  • Vehicle is running.
 
Item No.Item nameNormal condition
7Steering wheel angleNearly the same as the steering wheel operation angle (-720 to 720 deg)
OK: Normal condition is displayed.
Is the check result normal?
Go to Step 3.
Replace the column switch assembly (integrated with steering wheel sensor) (Refer to Column Switch Assembly Removal and Installation ).
 
STEP 3. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the BSW-ECU (master).
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if the diagnosis code is set.
Is the diagnosis code set?
Replace the column switch assembly (integrated with steering wheel sensor) (Refer to Column Switch Assembly Removal and Installation ). Then go to Step 4.
Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 4. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the BSW-ECU (master).
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if the diagnosis code is set.
Is the check result normal?
This diagnosis is complete.
Replace the BSW-ECU (master).
